Deep Dive into an Obfuscation-as-a-Service for Android Malware

While confined in our homes studying the interactions of individuals involved in the spread of the Android banking Trojan botnet (known as Geost), we encountered a unique opportunity: investigate an automated obfuscation-as-a-service platform for Android malware authors.

Indeed, in a leaked chat log that involved Geost botnet operators, two individuals talked about an obfuscation service used to “protect” their malicious Android Applications (APKs) from being detected by antivirus engines. We visited the website related to the “protection” service (protection from antivirus engines -so basically obfuscation), which raised a lot of questions: How does this obfuscation service work? Is it automated? Does it really obfuscate applications well enough to avoid malicious applications being detected? How well is the service known in the underground community?
