Trailrunner7 writes "A new version of the venerable Alureon malware has appeared, and this one includes some odd behavior designed to prevent analysis and detection by antimalware systems. However, this isn't the typical evasion algorithm, as it uses some unusual encryption and decryption routines to make life much more difficult for analysts and users whose machines have been infected. Alureon is a well-known and oft-researched malware family that has some rootkit-like capabilities in some of its variations. The newest version of the malware exhibits some behavior that researchers haven't seen before and which make it more problematic for antimalware software to detect it and for experts to break down its components."
