Recently, automatic moving target defense (AMTD) is recognized as a promising proactive defense technique against cyber attacks. In particular, NTO (Network Topology Obfuscation) is an emerging AMTD approach for dynamic reconfiguration of network infrastructure/configuration. In our new research that will appear in USENIX Security’24, we introduce a new CrossPoint attack that can escape the security protections of state-of-the-art NTO defenses. Congratulations, Xuanbo!
