What it detects

This rule detects HTTP requests to the Ivanti Connect Secure /api/v1/cav/client/visits endpoint that WIREFIRE trojanizes into a webshell. Suspected APT actors modified this component to accept encrypted commands and payloads through crafted requests to that URI. Traffic to this specific tampered API path signals interaction with the WIREFIRE backdoor.
