msaRAT CDP C2 Sequence Correlated Within Same Debugger Session
Detects the combined msaRAT CDP C2 sequence within a single event - Page.setBypassCSP disabling Content Security Policy, all five Runtime.addBinding callback registrations (msaOpen, msaClose, msaError, msaMessage, dataAck), and a Runtime.evaluate call injecting JavaScript that establishes an RTCPeerConnection. All three behaviors must be present together, reducing false positives from unrelated CDP activity.
