It seems smartphone malware authors are diligent and hard-working to protect their own "intellectual property" -- malware by evolving/bringing them to the next level. After discovering the originalDroidKungFu malware in June and its variant in July, our research team, in collaboration with NetQin, recently identified a new wave of DroidKungFu-infected apps this August. The new variant is much more "advanced" than previous versions -- as it is clearly designed to evade the detection from existing mobile anti-virus software. More specifically, this variant is equipped with new protection mechanisms by (1) obfuscating remote C&C server URLs (instead of including them as plaintext in earlier versions); (2) hiding all malware-related native binaries with encryption; and (3) masquerading an embedded app as the official Google Update.
