Researchers at Black Hat USA will release a toolset that studies and then cheats specific Android AV apps.
A team of researchers from Georgia Tech built an Android hacking tool that snuck past nearly all of 58 Android AV antivirus programs in tests conducted via VirusTotal.

Their AVPass toolkit includes a query function that vets and probes an Android AV program’s detection capabilities, a malware variant generator that generates multiple variations of a sample, and a data analyzer that analyzes the findings and uses that information to ultimately bypass AV apps on a mobile device.
