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).
