Cybersecurity in 2023: Technologies and Trends Shaping the Current State of Security

Cybersecurity is an ever-evolving field, with cyber criminals adapting their skills and targets according to the maturity in security defenses being put in place by large organizations or the lax shown by some others in this space. Small and medium businesses are not spared as well. As technology advances, so do cyber criminals’ attack vectors and their means of exploiting the vulnerabilities.

It is beyond doubt that cybersecurity is critical for protecting personal and sensitive business and client data held by these organizations or their contracted third-party vendors. No network is safe from intrusions, and data breaches and the aftermath of cybercrime can cost these organizations dearly. As PurpleSec notes, the annual cost of cybersecurity has increased by 22.7% since 2021, with the average cost of a data breach to small businesses alone ranging from $120,000 to $1.24 million (PurpleSec, 2023).

Organizations must rely on cyber security professionals to maintain the right level of defenses to protect the data they are liable for. These professionals must stay current with the latest cybersecurity resources, threats, and insights to tackle the escalating crisis. Whether an organization is securing its critical infrastructure, network, applications, or Internet of Things (IoT) devices, staying aware of threat vector surfaces and the most recent cybersecurity trends can help them prepare for cyber attacks against their organization.

This blog discusses some of the top cybersecurity trends worth keeping in mind in 2023 and beyond.

Top 4 Cybersecurity Trends You Need to Know in 2023 

Despite the efforts to bring the focus of enterprises on the cyber security trends for more than a decade, cybersecurity attacks have proliferated, more so in recent years across multiple industries. Cybercriminals are furthering their malicious objectives with sophisticated techniques taking advantage of the rapid digital transformation that businesses are undergoing.

As Ivana Vojinovic from Data Prot notes, 70% of small businesses are unprepared for incoming threats, and 88% of seasoned unethical hackers can infiltrate organizations within 12 hours (2022). The total damages caused by cybercrimes in 2022 reached USD 6 trillion. Based on the statistics put together from various sources, Ivana cited that over 33 billion accounts are estimated to get breached by 2023 (Vojinovic, 2022). While there is no telling yet, if these predictions will be close to the actual numbers, it does provide the enterprises with a sense of urgency and a direction to improve their security posture.

Next, let’s look at some emerging trends and insights that will prevail in the cybersecurity space.

1. Hybrid Cloud and Multi-Cloud Security

Cloud security is a concern of great importance. Over the years, enterprises have been migrating their workloads to Cloud in the interest of optimizing their business costs. But in recent years, the trend has been to adopt a multi-cloud or hybrid cloud approach with the aim of maintaining critical workloads within the enterprise boundary while using service features from different cloud providers that best meet the business requirements. Some enterprises have also taken the approach of migrating off the Cloud due to cost, performance, and security considerations. Such architectural changes and migrations require that enterprises can hire the right talent and have skilled cybersecurity professionals engaged in putting the right security defenses and data protection mechanisms in place throughout.

From mobile banking apps to e-booking platforms, and online shopping stores, opportunities have grown for hackers to breach user accounts and steal personal information. IoT is an emerging technology being integrated with cloud applications, leaving data vulnerable. More patient records are being stored online in the Cloud, and unethical hackers are devising new social engineering tactics to target hospital patients, putting the healthcare sector at serious risk. Despite the ever-growing list of security and privacy compliance programs that are being mandated by consumer-regulated industries, misconfigurations, and human errors are major roadblocks to cloud security.

Phishing attacks continue to be highly prevalent, and the Cloud is being used to disseminate malware and other malicious programs for carrying out massive cyberattacks. As newer technologies are introduced, there will be a rapid proliferation of newer threats which means cyber criminals will have more opportunities for launching cyber-attacks and causing a greater number of security breaches with a higher impact on enterprise business and brand. Being aware of the latest cybersecurity trends and knowing what to expect for 2023 and beyond can help (Staff, 2023) enterprises to build their defenses better.

Cloud solutions also rely on supply chain managers to integrate their solutions with other cloud solutions or with business systems. This increases the risk of supply-chain attacks or value-chain attacks due to the broader attack surface that now becomes available to the attackers. Although some of the regulatory and other security compliance frameworks mandate regular supply chain vendor assessment, due diligence on the part of enterprises is critical to reducing risks associated with supply-chain attacks.

Enterprises will need to ramp up their security strategies to safeguard their cloud architecture through identity and access management, data awareness and protection, monitoring vulnerabilities, etc. Cyber risks are diversifying, and information technology (IT) security needs to revamp its outdated methods and techniques to stay abreast of cybersecurity threats. Enterprises are updating their security policies and addressing insecure application programming interface (API) concerns to tackle Cloud misconfigurations.

Improving architectural visibility, enabling Multi-factor Authentication (MFA) and artificial intelligence (AI) solutions, and adopting the policy of Zero Trust Access (ZTA) to networks are some ways enterprises are addressing Cloud vulnerabilities and security threats, among many other measures.

2. Advanced Persistent Threats (APTs)

Advanced Persistent Threats (APT) are carefully planned attacks that let intruders go undetected in networks, enabling them to steal sensitive information over prolonged periods. APTs can disrupt business operations and gain unauthorized access to systems without users’ knowledge. There is also a major gap in comprehending the APT nexus and mitigating these risks, which also negatively impacts the APT protection market.

Some APTs are full-blown in scale, and military-grade APTs are geared toward nations’ infrastructures and government institutions. In the analytical report on the ongoing cyber warfare being faced by Ukraine, “Web-based vulnerabilities and persistence methods” were identified as the top cybersecurity incidents in 2022 due to the persistent attacks from various APT groups aimed at “(causing) disruption to spying and data theft” (SSSCIP, 2023).

APTs can target various sources such as the web, email, software, physical computer systems, etc. Accounts can be compromised through various means via these threats, such as phishing and social engineering campaigns. The goals of APT attacks fall into four categories – cyber espionage, destruction of data, hacktivism, and crimes for financial gain. Operational Technology (OT) cybersecurity will be an emerging breeding ground for APTs as hackers attempt to take control of the Industrial Control Systems (ICS) installed with outdated and vulnerable software. There is a need for integrated security and technological development to boost the services for the advanced threat protection market, which is expected to grow at an unprecedented rate soon. For now, most enterprises can invest in Web Application Firewalls and API gateways to secure their web applications and manage business assets. They will be paired with modern API security solutions to identify misconfigurations and prevent API-related cyber-attacks. Frequent patching and hardening of the infrastructure, network, and software components will enable enterprises to reduce risk exposure to their critical systems.

3. Uncertainty of the Metaverse

As metaverse popularity grows, with market value expected to reach USD 237 Billion by 2027 (Research and Markets, 2023), user accounts in the metaverse will become lucrative targets for spoofing and data theft. In 2022, PwC survey highlighted that more than 66% of surveyed executives were engaged with the metaverse platforms (PwC, 2022). While there has been an initial interest from industries like finance, entertainment, retail, etc., enterprise strategies on augmented reality (AR) and virtual reality (VR) are currently taking a backseat in the speculations of a global recession. Current users of these AR headsets stand to lose as they may get reduced software support from the metaverse vendors who are bearing the impact of changing strategies.

Avatar hijacking will be a common threat scenario if the metaverse becomes a major hub for conducting financial transactions. Integration with various cutting-edge technologies such as Natural Language Processing (NLP), Artificial Intelligence, Edge Computing, and Blockchain ledgers will add to the security concerns. Generative AI has managed to gain interest from everyone around the world due to its capability to create human-like and realistic text, animation, and videos in minutes. Integration with metaverse will accelerate runtime content creation, but it will also make it challenging for anyone to identify if a conversation involves another human or an interactive machine. As technology keeps evolving, AI-generated avatars will be deemed more trustworthy than real faces, and users online will not be able to tell the difference between the two.

Brand phishing and malware attacks are expected to be among the top risks, next to biometric hacking, impersonation, and identity theft. Terrorist groups can leverage misinformation to spread their propaganda and launch wide-scale attacks by hijacking cutting-edge technologies like Augmented Reality (AR) and Virtual Reality (VR) environments. There are dangers associated with hijacking haptic sensors in virtual environments, and generative AI can lead to impersonation fraud. Edge computing, used for optimizing network latency and bandwidth, is a cause for security concerns such as DoS attacks, technical glitches, and challenges with content moderation.

Establishing coding standards and communication protocols to ensure the information being shared is authentic is a good way to avoid falling victim to deep fakes and impersonation threats in the metaverse. Machine Learning and AI can be leveraged to detect AI-based attacks as well and enable high-level security automation as well.

4. Post-Quantum Cryptography

Another interesting trend is the importance of adopting post-quantum cryptography (PQC) or quantum-safe cryptography, as some may term it. As the Quantum Computing vendors continue to make advances in their research and roll out large-scale Quantum Computers, the threat to our global information infrastructure becomes real.

The modern-day cryptographic algorithms that are widely used to protect our digital data and authenticate our identity are dependent on certain mathematical problems that are difficult to solve using classical computers in a reasonable time. This includes popular encryption and public key algorithms like RSA and Elliptic Curve. However, due to the fundamental differences in the way a Quantum Computer works, these mathematical problems that classical computers may take millions of years to solve can now be solved in a matter of hours or minutes, provided the Quantum Computer is sufficiently large. Although these large-scale quantum computers are not available today, the technology is advancing at a rapid pace. In 2022, IBM unveiled the 433-qubit Osprey processor, with a target of delivering a 1,121-qubit Condor processor in 2023 along with the Heron processor, which will become the steppingstone to solving the quantum computing scaling problem (IBM, 2023).

Thanks to efforts driven by government agencies like NIST and contributions from organizations (including IBM) and cryptographers to develop quantum-resistant public-key cryptographic algorithms, NIST is expected to publish the PQC standard by 2024. Considering that crypto migration would be a multi-year project with current cryptographic systems still in their multi-year lifespan before new PQC-enabled systems can be put in place, NIST states that “we must begin now to prepare our information security systems to be able to resist quantum computing” (NIST, 2022) to protect the integrity and privacy of the data. Some of the industries, like telecommunications, have already started engaging with experts to assess the impact on the telecom industry and the need for “PQC adoption to secure networks, devices, and systems” (GSMA, 2023).

How Can You Stay Ahead of the Emerging Cyberthreats

The risk appetite of every enterprise varies based on the nature of the business, market economy, company culture, competitors, etc. Irrespective, no risk analysis is complete without considering the cybersecurity risks. Cybersecurity aims to ensure data security and privacy and provides flexibility to enterprises for sharing and transmitting data online to make their business more profitable. By promoting a culture of cyber awareness and adopting the best practices for safeguarding personal and business information, enterprises can stay ahead of the curve and proactively protect themselves against emerging cyber threats.

Both the volume and the severity of cyberattacks have been increasing, and enterprises need to continue evaluating and enhancing security measures to mitigate any security risk that is detrimental to business. Enterprises must stay current with offensive and defensive security measures. They must engage their staff in regular cybersecurity training and keep them updated with emerging risks associated with adopting new platforms and next-gen technologies. Security professionals and leaders need to align their strategies and best practices incrementally with their business objectives to establish advanced threat protection and improve cyber resiliency. After all, cybersecurity preparedness cannot happen overnight.

What Is Spear Phishing?

In the digital age, phishing scams have become increasingly common, and as a result, many people have become aware of the dangers associated with clicking on links or downloading files from unknown sources. However, there is a more sophisticated and targeted form of phishing that is on the rise, and that is spear phishing. In this article, we will explore what spear phishing is, how it differs from other types of phishing, and how you can protect yourself from falling victim to these scams.

Introduction

Spear phishing is a form of cyber attack that targets specific individuals or organizations with the goal of stealing sensitive information such as login credentials, financial information, or intellectual property. Unlike regular phishing scams that send out mass emails in the hopes of catching a few unsuspecting victims, spear phishing attacks are highly targeted and personalized.

What Is Phishing?

Phishing is a type of cyber attack that involves sending out fraudulent emails, text messages, or social media messages in an attempt to trick the recipient into divulging sensitive information. The information that is typically targeted includes usernames and passwords, credit card numbers, and other personal or financial information that can be used for fraudulent purposes.

How Is Spear Phishing Different From Regular Phishing?

The main difference between spear phishing and regular phishing is the level of sophistication and personalization involved. Regular phishing attacks are usually mass-produced, generic emails that are sent out to a large number of recipients in the hopes of tricking a few people into clicking on a link or downloading a file.

In contrast, spear phishing emails are highly targeted and personalized. The attackers will often spend time researching their victims in order to craft an email that appears to be legitimate and convincing. These emails are designed to look like they are coming from a trusted source, such as a colleague, friend, or business partner.

How Do Spear Phishing Attacks Work?

Spear phishing attacks typically involve several stages. The first stage is reconnaissance, where the attackers research their targets in order to gather information that can be used to craft a convincing email. This may involve looking at social media profiles, company websites, or other publicly available information.

Once the attackers have gathered enough information, they will craft an email that appears to be from a trusted source. The email will typically include a message that is designed to elicit a response from the recipient, such as a request for login credentials or other sensitive information.

If the recipient falls for the scam and provides the requested information, the attackers can then use this information to gain access to the victim's accounts or steal sensitive data.

Who Are the Targets of Spear Phishing Attacks?

Spear phishing attacks can target anyone, but they are most commonly directed at individuals who have access to sensitive information or who are in positions of authority within an organization. This includes executives, managers, and other high-level employees.

Why Is Spear Phishing So Effective?

Spear phishing attacks are often successful because they are highly personalized and appear to be coming from a trusted source. The attackers will often use social engineering techniques to create a sense of urgency or importance in their email, which can make the recipient more likely to respond without thinking. Additionally, spear phishing emails are often crafted with a high level of attention to detail, which can make them difficult to distinguish from legitimate emails.

What Are the Consequences of Falling Victim to a Spear Phishing Attack?

The consequences of falling victim to a spear phishing attack can be severe. Depending on the type of information that is stolen, the attackers may be able to access the victim's financial accounts, steal intellectual property, or compromise sensitive company data. In some cases, the attackers may also use the stolen information to carry out further attacks, such as identity theft or ransomware attacks.

How Can You Protect Yourself from Spear Phishing Attacks?

There are several steps that you can take to protect yourself from spear phishing attacks:

Use Strong Passwords

Using strong, unique passwords for each of your online accounts can help prevent attackers from accessing your accounts even if they do manage to steal your login credentials.

Keep Your Software Up to Date

Keeping your software up to date can help prevent attackers from exploiting known vulnerabilities in your system.

Use Antivirus and Antimalware Software

Antivirus and antimalware software can help detect and remove malicious software that may be used in spear phishing attacks.

Be Suspicious of Unsolicited Emails

Be wary of unsolicited emails, especially if they are requesting sensitive information or seem too good to be true.

Don't Click on Links in Emails

Avoid clicking on links in emails, especially if they are from unknown senders or if they appear to be suspicious.

Verify Email Addresses and Domains

Verifying email addresses and domains is an important step in ensuring the security and authenticity of your online communications. By verifying an email address or domain, you can confirm that the sender is who they claim to be and that the message has not been tampered with.

To verify an email address, you can use a verification service or software that will check the email address against known databases of fraudulent or suspicious email addresses. Some email providers, such as Gmail and Outlook, also offer built-in tools for verifying email addresses. These tools typically involve sending a verification code to the email address in question and requiring the recipient to enter the code to confirm their identity.

To verify a domain, you can use a domain verification service or software that will check the domain against known databases of fraudulent or suspicious domains. Some web hosting providers, such as GoDaddy and Bluehost, also offer built-in tools for verifying domains. These tools typically involve adding a specific record to the domain's DNS settings to confirm ownership.

Verifying email addresses and domains is an important step in preventing email fraud and phishing scams. By taking the time to verify the authenticity of senders and domains, you can help to protect yourself and your organization from cyber threats.

Use Two-Factor Authentication

Two-factor authentication (2FA) is a security process that requires two different authentication methods to verify a user's identity. The first factor is typically a password or PIN, while the second factor can be a fingerprint scan, facial recognition, a security token, or a one-time code sent to the user's phone or email.

Using 2FA adds an extra layer of security to your accounts and helps to protect them from unauthorized access. Even if someone manages to obtain your password, they won't be able to log in without the second factor of authentication. It's important to enable 2FA on all of your accounts that offer it, especially those that contain sensitive information such as banking, email, and social media accounts.

To enable 2FA on your accounts, go to the security settings and follow the instructions to set up the second factor of authentication. Once you've set it up, you'll be prompted to provide the second factor each time you log in from a new device or location. It may take a few extra seconds to log in, but it's worth it to ensure that your accounts are secure.

Conclusion

Spear phishing attacks are a growing threat in the digital age, and it is important to be aware of the risks and take steps to protect yourself. By following the tips outlined in this article, you can help prevent yourself from falling victim to a spear phishing attack.

What is Spear Phishing and How Can You Prevent It

Spear phishing is one of the biggest cybersecurity threats that organizations must know. According to Symantec’s Internet Security Threat Report (ISRT), 65% of threat actors have used spear phishing emails to attack. Deloitte estimates that 91% of successful cyberattacks begin with a phishing email.

So, what is spear phishing, and how can you best protect yourself? This article discusses everything you need to know, including a few common examples and their types.

What Is Spear Phishing?

Spear phishing means using targeted emails to a specific person from an attacker attempting to impersonate a trusted third party. A spear phishing email aims to trick the recipient into taking an action that allows the sender to execute a cyberattack.

Users may be fooled into downloading malware or revealing their credentials, such as their username and password. This tactic lets the attacker enter the user’s network undetected and steal data or bring down the environment from within. Attackers may also seek information such as credit card numbers, Social Security numbers, and bank accounts that allows them to commit financial fraud.

Because it involves a targeted attack on a single individual or business, spear phishing requires malicious actors to conduct research and reconnaissance on their would-be victims. Hackers may use knowledge such as the targets’ personal and business connections, employers, residence, and even recent online purchases.

Phishing vs. Spear Phishing: What’s the Difference?

It can be easy to get confused about phishing vs. spear phishing. Both terms refer to email attacks that attempt to extract confidential or personal information by impersonating a trusted third party. In particular, spear phishing (a targeted spoof email to a specific recipient as the prelude to a cyberattack) is a subtype of a phishing attack.

The difference between phishing and spear phishing is that phishing is not necessarily aimed at a single target (i.e., an individual or organization). Importantly, many phishing emails do not fall under spear phishing.

For example, mass phishing campaigns attempt to cast their nets to reach as wide an audience as possible. These attacks often impersonate a large, trusted business — such as Amazon or a credit card company — that thousands or millions of people patronize.

On the other hand, spear phishing always has an intended victim in mind. By customizing their attacks to use knowledge of the target, threat actors hope to make spear phishing more sophisticated and effective than a general phishing campaign.

4 Types of Spear Phishing

Spear phishing is a subclass of phishing, but you should be aware of also varieties of spear phishing. Below are some common types of spear phishing:

◉ Whale phishing: Also called “whaling,” whale phishing aims at particularly wealthy or important individuals, such as business executives. Whaling is an effective spear phishing because these targets often have access to funds or IT resources that lower-level employees do not.

◉ Angler phishing: This type of spear phishing targets dissatisfied customers of a business on social media. The attackers pose as representatives of the company, asking customers to provide them with sensitive data to “investigate” their cases.

◉ Barrel phishing: Barrel phishing is a phishing attack that targets many individuals or organizations at once, using a standardized message or template. The name “barrel phishing” refers to the idea that a large number of victims are targeted at once, like fish in a barrel

◉ Clone phishing: An attempt to mimic the previous messages of a legitimate sender is known as clone phishing. However, the attackers replace the attachments or links in the previous email with malware or a spoofed website that steals users’ data.

Best Practices and Tips

The good news is that there are steps you can take to prevent spear phishing attacks. Follow the security tips and best practices below to defend yourself against spear phishing:

◉ Educate and train employees on recognizing phishing and spear phishing campaigns.

◉ Conduct phishing simulations to evaluate the effectiveness of training campaigns.

◉ Scan external links and email attachments for suspicious behavior.

◉ Install antivirus and antimalware software.

◉ Regularly update software and hardware to patch security vulnerabilities.

In particular, spear phishing attacks can be stopped or limited by practicing good cyber hygiene, making it more difficult for attackers to learn about their targets. For example, businesses should avoid publishing email and phone numbers for their employees on their website; visitors can use a contact form to reach out. This method makes it harder for malicious actors to impersonate employees by faking the address in an email header.

A Guide to Steganography: Meaning, Types, Tools, & Techniques

From invisible ink to highly complex algorithms, steganography is all around us. Steganography is a fascinating and often misunderstood technique of concealing information, and it has experienced a revival in the digital world. This article discusses everything you need to know about steganography and its applications in cybersecurity: the definition of steganography and various steganography types, tools, and techniques.

What Is Steganography, and How Does It Work?

Simply put, steganography is the practice of “hiding in plain sight.” Steganography encodes a secret message within another non-secret object in such a manner as to make the message imperceptible to those who aren’t aware of its presence. Of course, because of this secrecy, steganography generally requires the recipient to be aware that a message is forthcoming.

To understand the meaning of steganography, it’s important to know the origins of the technique. The practice of steganography dates back to ancient Greece, from which we also get the word itself: a combination of the Greek words “steganos” (covered or concealed) and “graphein” (writing).

For example, the Greek historian Herodotus wrote about how Spartan warriors used steganography to conceal military intelligence from the enemy. The Spartans would write messages on wood tablets and cover them with wax, hiding the information in case the messenger was intercepted. The recipient could then scrape off the wax and easily read the message.

The Difference Between Steganography, Cryptography, and Obfuscation

Steganography, cryptography, and obfuscation are three related terms; they all refer to practices that make data more difficult to understand. However, these words are not interchangeable — subtle yet crucial distinctions exist between them.

Below are the differences between steganography, cryptography, and obfuscation:

◉ Cryptography attempts to encode a message, making it difficult or impossible for anyone except the intended recipient to decrypt it. The encoding and decoding process is accomplished using cryptographic keys that translate back and forth between the true message and its encrypted version.

◉ Steganography attempts to hide a message within another object. Not only does steganography seek to make this information harder to understand, but it also seeks to conceal that a message is being sent in the first place.

◉ Obfuscation is any technique that prevents third parties from understanding a message. For example, a program’s source code may be obfuscated by removing the whitespace, making the message difficult for humans to read.

Note that steganography and cryptography are not mutually exclusive. For example, steganography could hide a message inside another file using encryption for extra security. The recipient could then extract the encrypted message and decrypt it using a given key.

Examples of Steganography

Steganography has been in use for centuries. Basic physical forms of steganography include invisible ink that can only be read by exposing it to heat and messages written under the postage stamps of an envelope.

However, clever practitioners of steganography have developed a range of more sophisticated techniques that work in various mediums. One example is a laser printer’s Machine Identification Code (MIC), a unique identifier encoded on any printed document using tiny yellow dots that are invisible to the naked eye. Secret messages can even use the letters of a crossword or the numbers of a sudoku puzzle.

More recently, digital stenography has emerged as a practice with both legitimate and criminal uses. The different algorithms in digital steganography include:

◉ Least significant bit (LSB): In the LSB algorithm, the least significant bit in each byte of a multimedia file (e.g., an image or audio) is modified to convey a hidden message.

◉ Multi-access edge computing can also help save on bandwidth costs and improve security by processing data locally instead of sending it over the network to central servers.

◉ Discrete Fourier transform (DFT): In the DFT algorithm, information is hidden inside a multimedia file using the mathematical technique of discrete Fourier transformation.

The good news for users of steganography is that they don’t have to code these algorithms from scratch. Instead, different programming languages come with pre-built steganography libraries and frameworks. For example, the Python Stegano module can hide messages within an image (PyPI), while the ImageSteganography library does the same for C++ programmers (GitHub, 2022).

In the next section, we’ll go over five of the most common types of digital stenography.

What Are the 5 Types of Steganography?

1. Text steganography

Text steganography conceals a secret message inside a piece of text. The simplest version of text steganography might use the first letter in each sentence to form the hidden message. Other text steganography techniques might include adding meaningful typos or encoding information through punctuation.

2. Image steganography

In image steganography, secret information is encoded within a digital image. This technique relies on the fact that small changes in image color or noise are very difficult to detect with the human eye. For example, one image can be concealed within another by using the least significant bits of each pixel in the image to represent the hidden image instead.

3. Video steganography

Video steganography is a more sophisticated version of image steganography that can encode entire videos. Because digital videos are represented as a sequence of consecutive images, each video frame can encode a separate image, hiding a coherent video in plain sight.

4. Audio steganography

Audio files, like images and videos, can be used to conceal information. One simple form of audio steganography is “backmasking,” in which secret messages are played backwards on a track (requiring the listener to play the entire track backwards). More sophisticated techniques might involve the least significant bits of each byte in the audio file, similar to image steganography.

5. Network steganography

Last but not least, network steganography is a clever digital steganography technique that hides information inside network traffic. For example, data can be concealed within the TCP/IP headers or payloads of network packets. The sender can even impart information based on the time between sending different packets.

Steganography Tools and Techniques

There are many different types of steganography — so how can you get started? Fortunately, there are a number of tools for using steganography online.

OpenStego is an open-source steganography tool that offers two main functionalities: data hiding and watermarking (i.e., hiding an invisible signature). As of this writing, OpenStego works only for image files (Vaidya, S).

Another free steganography tool (though not open-source) is OpenPuff. The OpenPuff software supports steganography in image, audio, and video files and can even split a message across multiple files (EmbeddedSW).

How Do Malicious Hackers Use Steganography?

As you might imagine, steganography can be used for both good and ill. For instance, dissidents living under oppressive regimes can use steganography to hide messages from the government, passing sensitive information within a seemingly innocuous medium.

However, digital steganography is also a tool for malicious hackers. An attacker can hide the source code for a malware application inside another supposedly harmless file (such as a text file or an image). A separate program can then extract and run the source code.

In June 2020, for example, security researchers at Malwarebytes discovered that malicious actors had hidden code for a web skimmer inside the EXIF metadata of an image file. When executed, this code silently captured the details of users as they entered their names, addresses, and payment card information on e-commerce websites (Segura, 2020).

Cybercriminals use various methods to gain unauthorized access to your devices and steal your personal information, financial data, and other sensitive information.

The consequences of a cyber attack can be severe and long-lasting. Identity theft can result in the loss of your credit score, financial loss, and damage to your reputation. Cyber attacks on businesses can result in data breaches, financial losses, and damage to brand reputation.

Common Cyber Threats

There are various types of cyber threats that you need to be aware of to protect yourself from cyber attacks. Some of the most common types of cyber threats include:

Malware

Malware is malicious software that is designed to damage or disrupt your computer system. Malware can include viruses, worms, and Trojan horses. Malware can infect your system through email attachments, software downloads, or malicious websites.

Phishing

Phishing is a type of cyber attack where cybercriminals try to trick you into revealing your personal information or login credentials. Phishing attacks can be in the form of emails, text messages, or phone calls.

Man-in-the-Middle Attacks

Man-in-the-Middle attacks are when cybercriminals intercept your communication and eavesdrop on your conversation. Cybercriminals can use this method to steal your personal information, login credentials, or financial data.

Ransomware

Ransomware is a type of malware that encrypts your files and demands payment to restore access to them. Ransomware can be delivered through email attachments or malicious websites.

Social Engineering

Social Engineering is a technique used by cybercriminals to manipulate people into revealing their personal information. Cybercriminals can use various tactics such as impersonation, deception, or intimidation to trick people into giving away their personal information.

How to Protect Yourself

There are various steps you can take to protect yourself from cyber attacks. Here are some effective ways to keep your digital life safe and secure:

Use Strong Passwords

Use strong and unique passwords for all your online accounts. Avoid using common passwords such as your name or birthdate. Use a mix of uppercase and lowercase letters, numbers, and special characters to create a strong password.

Keep Your Software Up-to-Date

Make sure to keep your operating system and software up-to-date with the latest security patches. Software updates often include security improvements and bug fixes that can help protect your system from cyber threats.

Use Antivirus Software

Antivirus software can help protect your computer from malware and other cyber threats. There are many free and paid antivirus software options available, so be sure to do your research and choose one that fits your needs.

Enable Two-Factor Authentication

Two-factor authentication adds an extra layer of security to your online accounts. It requires you to enter a code sent to your phone or email in addition to your password to log in. This makes it harder for cybercriminals to gain unauthorized access to your accounts.

Be Cautious of Suspicious Emails and Links

Be careful when opening emails or clicking on links from unknown sources. Cybercriminals often use phishing emails or links to trick you into revealing your personal information or login credentials. Always verify the authenticity of the sender and avoid clicking on suspicious links.

Use a Virtual Private Network (VPN)

A Virtual Private Network (VPN) encrypts your internet connection and protects your online activity from prying eyes. It can help you browse the internet securely and anonymously, especially when using public Wi-Fi networks.

Secure Your Home Network

Secure your home network by using a strong and unique password for your Wi-Fi network. Change the default password provided by your internet service provider (ISP). Also, consider using a firewall to prevent unauthorized access to your network.

Conclusion

Cybersecurity is crucial to protect your digital life from cyber threats. By taking the necessary steps to secure your devices and online accounts, you can avoid becoming a victim of identity theft, financial fraud, or data breaches. Always be vigilant and cautious when using the internet and follow the best practices of cybersecurity.

Five Security Vulnerabilities Ethical Hacking Can Uncover

While the term “ethical hacking” may sound like an oxymoron, ethical hackers are an incredibly valuable resource for organizations today. Whereas malicious hacking is harmful, ethical hacking is beneficial—when done right, it can protect a company’s digital assets and ensure the security of its network.

As a result, ethical hacking skills are in high demand today: A recent report projects that there will be 3.5 million cybersecurity job openings by 2025 (Cybersecurity Ventures, 2021), and ethical hackers in the United States make an average of $102,400 per year (Salary.com, 2021). If you’re looking to develop your ethical hacking skills and become a Certified Ethical Hacker (C|EH), now is the perfect time.

An ethical hacker’s job is to attempt to break into a company’s network, understand its security protections and precautions, and identify weaknesses (EC-Council, 2021c). After doing so, they present the company with a list of its security vulnerabilities as well as recommendations for improving security. Ethical hacking often goes hand in hand with other security measures, like penetration testing (EC-Council, 2021b).

In the course of their work, ethical hackers can find many types of network and security vulnerabilities. In this article, we’ll outline five major security vulnerabilities that ethical hacking can reveal.

1. Security Misconfigurations

Security misconfigurations happen when an organization improperly configures or fails to properly utilize all of a system’s security settings, enabling hackers to gain access to its network. A security misconfiguration is often a precursor to a powerful and aggressive attack on a network. Programs like the C|EH train ethical hackers to spot security misconfigurations and then provide recommendations for how a business can remedy them.

2. Injection Attacks

In an injection attack, a malicious actor injects a line of code into a program to gain remote access to an organization’s network (IBM, 2014). Injection attacks are often precursors to larger-scale cyberattacks on a database or website (IBM, 2014). However, appropriate security protocols can stop the malicious injection of code and, if enforced correctly, alert a network administrator. There are many types of injection attacks, with SQL injections among the most prevalent and damaging.

3. Vulnerable System Components 

One of the fundamental challenges in network security is ensuring that all aspects of a network’s systems are secure and up to date—a network is only as secure as its individual components. Using components with known vulnerabilities can create serious network security problems. Ethical hackers can identify these vulnerabilities and determine how to fix them. These fixes may include making improvements to existing security programs and providing recommendations for better security software.

4. Social Engineering

Malicious actors use social engineering tactics to break into an organization’s network by inducing individuals to provide information that enables the hacker to gain illicit access to the organization’s systems (National Institute of Standards and Technology, n.d.). Social engineering attacks may involve, for example, a malicious actor posing as a network administrator and sending out a phishing email to an organization’s members. If users are tricked into giving out their usernames and passwords, the attacker can gain unlawful access to the company’s network. 

Ensuring that employees are aware of social engineering and phishing techniques can lower the odds that such attacks will be successful (EC-Council, 2021a). A company is only as strong as its weakest link. Ethical hacking can help identify these weak links.

5. Authentication Vulnerabilities

Although every network has an authentication process, some networks have particular vulnerabilities that allow a skilled hacker to bypass these authentication measures and breach the network. A C|EH is trained to know what these vulnerabilities are, where to find them, and how to spot them.

Essential CISO Learnings

With cyberattacks on the rise, it’s no surprise that many enterprises are searching for a CISO to mitigate their security risk and bolster their defenses. Between 2021 and 2025, the percentage of Fortune 500 company board members with cybersecurity experience is predicted to rise from 17 percent to 35 percent (Lake, S. 2022). A chief information security officer (CISO) is a senior executive in an organization who is in charge of the organization’s information security. These individuals are hired by security-conscious businesses that want to protect their valuable information assets.

The CISO must leverage both non-technical and in-depth technical skills to protect the organization’s IT systems. Much goes into the CISO learning process, and effective CISOs must draw on their knowledge and experience to keep data and assets safe. This article will discuss everything you must know about the CISO position: roles, responsibilities, skillset, and the qualifications and certifications needed to be a CISO.

CISO Learning: Roles and Responsibilities

The roles and responsibilities of a CISO will vary significantly between organizations. For example, a large enterprise with countless legacy on-premises systems and massive amounts of confidential data will have very different security concerns from a tiny startup using software as a service (SaaS) and cloud computing.

However, several typical functions tend to emerge when comparing the CISO job across businesses. Below are the most common roles and responsibilities you should be aware of during the CISO learning process:

1. Developing and implementing an IT security program: CISOs must establish policies, procedures, and standards to improve the security of the organization’s IT systems, networks, resources, and data.

2. Ensuring regulatory compliance: CISOs must verify that the organization is compliant with the relevant laws, regulations, and industry standards, including any updates to these laws and regulations.

3. Protecting data and assets: CISOs must prevent malicious actors from gaining unauthorized access to sensitive data and IT assets, which would result in a cyberattack or data breach. To do so, CISOs implement security controls such as firewalls and data encryption to make it harder for attackers to steal information undetected.

4. Drafting incident response plans: After a security breach or other incident, the CISO is responsible for leading and coordinating the organization’s response, ensuring appropriate measures are taken to minimize and rebound from the event.

5. Managing IT security professionals: The CISO oversees other information security professionals in the organization. They set overarching goals and objectives for the IT security team and may be involved in hiring and training new team members.

6. Communicating with key stakeholders: The CISO acts as a spokesperson for information security concerns to senior leadership, such as other executives and the board of directors.

CISO Learning: The 5 Domains of a CISO

The field of information security is vast, so there’s a lot on your plate during the CISO learning process. For this reason, CISOs often obtain a cybersecurity management certification to prove their knowledge. To be effective in their jobs, CISOs should be familiar with the following five domains:

1. Governance, Risk, and Compliance

CISOs may be responsible for:

◉ Defining and implementing an IT governance program

◉ Establishing a framework for monitoring the governance program’s effectiveness

◉ Knowledge of best practices surrounding network security, cloud security, data encryption, identity and access management tools, and security protocols

◉ Experience in security testing methodologies, such as penetration testing and vulnerability scanning.

The CISO learning process should impart a broad range of technical skills to move smoothly between tasks—everything from business analysis and budget management to security architecture and digital forensics. Before being a CISO, individuals often served in a technical capacity for many years. CISOs may have served in technical roles such as security engineers, security analysts, network engineers, and software developers.

CISO Non-Technical Skills

As a leadership role in the C-suite, the CISO must also have many non-technical skills. The CISO learning process should develop a candidate’s communication abilities since much of the work of a CISO involves making presentations to other executives and key stakeholders. CISOs should also be skilled at administration and conflict management, acting as leaders and mediators across the organization.

Buffer Overflow Attack Types and Prevention Methods

Buffer overflows are a type of security vulnerability that can occur when too much data is sent to a program or function, causing the memory buffer to overflow. An attacker can then use this excess data to execute malicious code and take control of a system. Here we will discuss the different types of buffer overflow attacks and how you can prevent them from happening.

Read More: EC-Council Certifications

What Is a Buffer Overflow Attack?

A buffer overflow attack occurs when a malicious actor attempts to insert more data into a buffer than the buffer is designed to hold. This extra data can overwrite portions of adjacent memory, corrupting or destroying valid data and code. A buffer overflow can also cause a program to crash or allow the attacker to take control of the program (Cobb, M. 2022).

Buffer overflows are a common type of security vulnerability, particularly in legacy code or code not written with security in mind. They can be challenging to detect and exploit, but once an attacker successfully exploits a buffer overflow, they can gain complete control over the vulnerable system. Buffer overflows are one of the most common attacks used by malware and viruses to infect systems.

Errors in coding can cause buffer overflows, such as failing to check the bounds of a buffer before writing data to it. Input that’s not properly validated or sanitized can also cause them. For example, an attacker may attempt to inject malicious code into a program by providing input that includes a shellcode. If the program fails to validate or sanitize this input properly, the shellcode may be executed, compromising the system.

Buffer overflows are a serious security threat and should be mitigated using appropriate security measures. Failure to do so can lead to systems being compromised and data being leaked or corrupted.

Buffer Overflow Consequences

The most common outcome of buffer overflows is that the program crashes. This happens because the extra data written to the buffer overwrite other parts of memory, causing the program to lose track of where it should be and what it should be doing. In some cases, this can lead to the program executing code that was not intended by the programmer, which can cause all sorts of problems (M, Rodrigo).

An attacker can use a buffer overflow to gain control of a target’s computer. To achieve this, the attacker writes data to the buffer and includes code that the program will execute. This code can perform various actions, including downloading and running malicious software and stealing sensitive information.

Types of Buffer Overflow Attacks

Buffer overflow attacks are code injection techniques that exploit an application’s vulnerabilities to take control of execution flow. These attacks take advantage of programming errors that allow malicious input to overwrite parts of memory, resulting in unintended or malicious code execution (GeeksforGeeks, 2022).

Here are some main types of buffer overflow attacks:

◉ Stack-based buffer overflows occur when malformed input is written to a program’s call stack, corrupting important data structures or pointers.

◉ Heap-based buffer overflows occur when malformed input is written to the dynamic memory area of a program, corrupting data structures or pointers used by the program.

◉ Integer overflows are a special type of buffer overflow attack that can occur when an arithmetic operation results in a large value representing the data type. This can lead to unintended code execution if the resulting value is used to index into an array or modify a pointer.

◉ Unicode overflows are another type of buffer overflow attack that can occur when handling Unicode input. If an attacker can submit maliciously crafted Unicode data, it may be possible to overflow buffers and corrupt memory.

◉ Format string attacks are a code injection technique that exploits vulnerabilities in the way a program handles formatted input strings. By submitting carefully crafted input strings, an attacker can cause the program to leak sensitive information or even execute arbitrary code.

How to Prevent Buffer Overflows

Several measures can be taken to prevent buffer overflows. These include address space layout randomization (ASLR), data execution prevention, and operating system runtime protections.

ASLR is a technique that makes it harder for an attacker to predict where code will be executed in memory. This technique makes it more difficult to exploit buffer overflows, as the attacker would need to know the exact location of the code to inject their own malicious code.

Data execution prevention is another measure that can be taken to prevent buffer overflows. This technique prevents code from being executed in certain memory areas, such as the stack or heap. This makes it more difficult for attackers to inject code into these areas, as they would need to find a way to bypass the data execution prevention measures.

Operating system runtime protections are another line of defense against buffer overflows. These protections, including stack smashing protection (SSP), make it difficult for attackers to exploit a buffer overflow by making it harder to predict where code will be executed in memory.

The bottom line is that buffer overflow attacks are a real threat to your organization, but there are ways to protect yourself. You can implement the appropriate prevention measures by understanding the different types of attacks and how they work. In addition, staying up to date on new attack methods and regularly testing your security protocols ensures your systems are as protected as possible.

While there are many different types of attacks, buffer overflow attacks are among the most common. Pen testers can help organizations prevent data breaches and other security incidents by finding and exploiting these vulnerabilities.

EC Council’s Certified Penetration Testing Professional (C|PENT) program is designed for IT professionals who want to become penetration testers. It covers a wide range of topics, including buffer overflow attacks, and participants receive globally recognized certification upon successful completion.

If you’re interested in becoming a certified penetration tester, the EC Council’s C|PENT program is the place to start.
