PeerPress: Utilizing Enemies' P2P Strength Against Them

Free registration required

Executive Summary

The authors propose a new, active scheme for fast and reliable detection of P2P malware by exploiting the enemies' strength against them. Their new scheme works in two phases: host-level dynamic binary analysis to automatically extract built-in remotely-accessible/controllable mechanisms (referred to as Malware Control Birthmarks or MCB) in P2P malware, followed by network-level informed probing for detection. Their new design demonstrates a novel combination of the strengths from host-based and network-based approaches. Compared with existing detection solutions, it is fast, reliable, and scalable in its detection scope. Furthermore, it can be applicable to more than just P2P malware, more broadly any malware that opens a service port for network communications (e.g., many Trojans/backdoors).
