Quark Engine

Explore an innovative Android malware analysis engine developed from the perspective of Taiwan Criminal Law in this conference talk from Hack In The Box Security Conference. Learn about the five-stage order theory of Android malware, which mirrors the stages of committing a crime: permission requested, native API call, certain combinations of native API, calling sequence of native API, and APIs handling the same register. Discover how this approach allows for calculating threat levels of malware through defined weights and thresholds. Examine the Dalvik bytecode loader designed to counteract obfuscation techniques commonly used by malware. Gain insights into functionalities such as finding cross-references, tracing calling sequences of native APIs, and bytecode register tracing. Witness a case study demonstrating the engine's effectiveness against obfuscated Android malware. Get introduced to the open-source Quark Engine project, which includes the malware scoring system and Dalvik bytecode loader presented in this talk.
