Anti-virus programs for Android continue to remain vulnerable against different permutations of malware. Researchers say malware writers use stealthy mutations (morphing/obfuscations) to continuously develop malware clones. 8 out of 17 leading commercial anti-malware programs failed to detect any of the cloned applications, with an average detection rate of 51.4% for class morphing, 58.8% for method morphing and 54.1% for body morphing. The researchers say they intend to add more obfuscations at different levels as well as enable morphing of metadata information such as permissions that are embedded in an APK file.
