Agent Smith’s core malware is disguised as a JPG file, and encrypted with an XOR cipher.[1]


This type of attack technique cannot be easily mitigated with preventive controls since it is based on the abuse of system features.


Detection of steganography is difficult unless detectable artifacts with a known signature are left behind by the obfuscation process. Look for strings are other signatures left in system artifacts related to decoding steganography.
