What technique is primarily associated with image-based threat vectors?

The technique primarily associated with image-based threat vectors is steganography. This method involves hiding information within another medium, such as embedding a secret message within an image file. By manipulating the least significant bits of the image data, a sender can conceal information without significantly altering the appearance of the image itself. This allows the information to be transmitted in a way that is not readily detectable by casual observation or common security measures.

Steganography's unique approach to obscuring data makes it particularly relevant in discussions about image-based threats, as it leverages visual media—something that is extensively used in various forms of digital communication. By embedding malicious code or exfiltrated data within images, attackers can bypass many traditional security systems that might not scan image files as thoroughly as other types of files, which is why steganography is a critical concept in cybersecurity when analyzing image-related vulnerabilities.
