Steganography: What is it?

Steganography is a technique used to conceal the existence of a message within another file or message. This can be done by hiding the message within the data of an image, audio, or video file, or by using a secret code or cipher to encode the message.

In the world of IT security, steganography can be used as a covert communication method to transmit sensitive information without detection. For example, a government agency might use steganography to communicate with an undercover agent without alerting the adversary.

However, steganography can also be used by malicious actors to conceal the existence of malware or other malicious content. For example, a hacker might embed malware within an image file and send it to a victim, who would then inadvertently download and execute the malware.

To protect against the use of steganography in cyber attacks, organizations can implement measures such as using antivirus software to scan for hidden content, as well as training employees on recognizing and avoiding suspicious files.

In conclusion, steganography can be a valuable tool for secure communication in the world of IT security. However, it can also be used by malicious actors to conceal the existence of malware and other threats. To protect against these risks, organizations must implement effective security measures and educate employees on recognizing and avoiding potential threats.
