How Can Steganography Strengthen Cybersecurity?

At BestCybersecurityNews, we help entrepreneurs, solopreneurs, young learners, and seniors learn more about cybersecurity.

Steganography is a method for concealing information within files that may otherwise go undetected. This technique can be employed on images, sound, video and even text to keep sensitive data hidden away.
Steganography is often employed by cybercriminals to hide malware payloads and script files so it’s difficult for security analysts to detect. Attackers also employ it in order to bypass detection from security tools like antivirus software.

Steganography, an ancient technique for hiding sensitive data, has seen a resurgence in malicious actors’ use. Hackers are increasingly employing it to conceal malicious code within files as well as for other purposes.
Threat actors have been known to embed malware payloads within SVG images that are then embedded on eCommerce checkout pages in order to steal credit card information. Furthermore, they have hidden shellcode in JPEG files in order to deliver a malicious payload directly onto targeted systems.
Cryptography utilizes advanced encryption algorithms to protect data from prying eyes, while steganography simply replaces the least significant bit of a file’s data with an encrypted message. This can often fool the human eye and enable malware infections on an unaware user.
This can be a useful technique to obscure confidential messages and other sensitive information from those with oppressed free speech rights in countries. Additionally, it helps track the distribution of digital files or documents if they have been stolen and circulated fraudulently.
Steganography is a long-standing and widely used application, yet security vendors have been reluctant to adopt it as a cybersecurity solution due to the risks involved.
Steganography is similar to cryptography in many ways, with the main distinction being its reversibility. If a steganographic message is detected, it can be undone and the original information returned exactly as intended. This saves time and energy when trying to locate stolen or lost files or pieces of information.
Steganography can be a particularly vulnerable technique for hackers to use, according to Kaspersky Lab researchers Alexey Shulmin and Evgeniya Krylova in a blog post. Unfortunately, most anti-malware tools offer little to no protection against steganography.
Modern endpoint protection technologies go beyond static checks and basic signatures to detect obfuscation and other forms of steganography. This is because code hidden in images or other forms of obfuscation tends to be detected dynamically by a behavioral engine. Companies should adopt this approach so their defenders can quickly detect any instances of steganography.

How can Palette-Based Steganography Enhance Cybersecurity?

Steganography in cybersecurity refers to the practice of hiding or concealing information using encrypted messages embedded in images, video files, sound recordings, or other digital media types. It provides a secure method for transmitting sensitive data without it being visible to unauthorized individuals.
Steganography can be employed not only to hide or conceal information, but it’s also employed to protect a computer against unauthorized use by concealing malicious software (malware). A cyber security threat actor with access to a system could utilize steganography techniques in order to bypass detection by existing security measures on that system.
One steganographic technique useful in cybersecurity is palette-based steganography. This involves changing the color order of digital images or other bit-based media. Though low-tech, this low-tech method can be implemented in several ways and hide a significant amount of information.
Palette-based steganography can be applied to any digital image or other bit-based media that has a palette (the number of colors in an image). The most common algorithm that utilizes palette-based steganography is the discrete cosine transform (DCT), which alters the color composition of an image or bit-based media by altering its coefficients, thus hiding a hidden message within.
Steganography often employs the wavelet transform, which utilizes time-domain characteristics of an image or file to conceal a secret message. This technique has become one of the most popular options for steganography.
Steganography’s most critical characteristic is capacity (how much data can be hidden). A steganography algorithm’s capacity determines its steganographic strength, which is measured through several criteria, such as invisibility, undetectability, and robustness.
Steganography, or the practice of concealing sensitive data behind an image or other digital medium, is a widely used practice in cybersecurity. Kaspersky released a report in June 2020 detailing an attack that employed steganography techniques to disguise malicious macros on an Excel email attachment.

What secrets can be hidden with Steghide?

Steghide is a free, open-source tool that enables the hiding of data within other files like images or media. It’s especially helpful for encrypting sensitive data sent between hosts or secure messages between hosts in a network. This technology has been adopted by the military and several large organizations to protect their data from hacking attacks.
Cybersecurity threats are becoming more and more sophisticated, coming from devices, sensors, and other endpoints. As a result, cybercriminals use various obfuscation techniques to keep their activities hidden from detection by anti-virus or network intrusion detection systems.
It is therefore essential to become knowledgeable about steganography in order to protect yourself from these attacks. Doing so will not only safeguard your information, but also enhance the reputation of you as a security expert.
Steganography in cybersecurity is on the rise and poses a major risk to organizations, particularly those dealing with highly sensitive information. To stay competitive in their industry, security professionals need to stay abreast of threats and best practices. Businesses also must understand the significance of educating employees about security so they can be protected against attacks. Moreover, cybersecurity pros must continue learning new methods of obscuring data while being aware of all the tools available to them.
