Unpacking the Use of Steganography in Recent Malware Attacks
released on 2023-11-14 @ 09:48:23 AM
Steganography hides data within another file or medium, effectively making it invisible. Unlike encryption, which scrambles but clearly marks data as confidential, steganography camouflages the data, blending it in with its surroundings. This can be used to evade security defenses. Malicious code may be embed in image files or even network traffic, aiming to make it indistinguishable from regular, benign data. This way, the hidden malware is less likely to trigger security alerts.
