In cybersecurity, some ongoing espionage attacks have focused on separating certain Middle Eastern governments with their sensitive information. These attacks use a steganographic trick that hides a prior undocumented backdoor placed within the Windows logo, leaving the victims entirely in the dark.
This brand-new type of malware harnesses the power of steganography, which is essentially a process used to embed secret messages in a known document. Once the procedure is complete, the cyber-criminals can focus on discreetly extracting malicious code from a bitmap image of an old Microsoft Windows logo hosted on a GitHub repository.
Cybersecurity experts state that "disguising the payload in this fashion allowed the attackers to host it on a free, trusted service. Downloads from trusted hosts such as GitHub are far less likely to raise red flags than downloads from an attacker-controlled command-and-control (C&C) server."
Researchers also stress that "exploitation of vulnerabilities on public-facing servers provides it with a route into organizations, while custom tools paired with adept use of living-off-the-land tactics allow it to maintain a long-term, persistent presence in targeted organizations."
