Fueled by a recent boost in revenue, cybercriminals are developing increasingly sophisticated and advanced malicious applications. This new generation of malware is able to avoid most of the existing detection methods. Even behavioral detection solutions are no longer immune to evasion, mostly because existing solutions focus on the actions or characteristics of a single process. We propose shifting the focus from malware as a single component to a more accurate perspective of malware as multi-component systems. We propose a dynamic behavioral detection solution that identifies groups of related processes, analyzes the actions performed by processes in these groups using behavioral heuristics and evaluates their behavior such that even evasive, multiprocess malware can be detected. Using the information provided by groups of processes, once a malware has been detected, a more comprehensive system cleanup can be performed, to ensure that all traces of an attack have been removed and the system is no longer at risk.
