DeepSec Talk 2024: Blackbox Android Malware Detection Using Machine Learning and Evasion Attacks Techniques – Professor Dr. Razvan Bocu

Sanna/ September 18, 2024/ Conference

Over the past ten years, researchers have extensively explored the vulnerability of Android malware detectors to adversarial examples through the development of evasion attacks. Nevertheless, the feasibility of these attacks in real-world use case scenarios is debatable. Most of the existing published papers are based on the assumptions that the attackers know the details of the target classifiers used for malware detection. Nevertheless, in reality, malicious actors have limited access to the target classifiers. This talk presents a problem-space adversarial attack designed to effectively evade blackbox Android malware detectors in real-world use case scenarios. The proposed approach constructs a collection of problem-space transformations derived from benign donors that share opcode-level similarity with malware applications through the consideration of an n-gram-based approach. These transformations are then used to present malware instances as legitimate entities through
