The identified malware includes functions named self_modifying_wrapper(), decrypt_and_execute(), and polymorph_code(), indicative of polymorphic behavior that enables frequent mutation of the code signature to evade detection. Polymorphic malware poses challenges to signature-based security systems due to its ability to alter its appearance in each execution. The specific RAT in question was submitted to VirusTotal and received a very low detection score of 2 out of 64, highlighting its potential to bypass many antivirus engines.
This minimal detection rate implies that current security tools may struggle to identify this threat effectively, increasing the risk of successful compromise. The use of such advanced evasion techniques suggests the malware could be used in targeted attacks or widespread campaigns to gain unauthorized access and control over infected systems. Organizations should be cautious and consider employing behavior-based and heuristic detection methods alongside signature-based tools to mitigate such evolving threats.
The presence of this RAT underscores the continuous advancement of malware technology and the importance of ongoing vigilance and adaptive defense strategies in cybersecurity.
