This rule detects potential adversary activity by correlating the execution of known analysis or debugging tools (e.g., Wireshark, ProcessHacker, x64dbg) occurring within a 30-minute window of a process executing from suspicious, user-writable directories (typically AppData/Local or AppData/Roaming). This pattern is often indicative of an adversary staging tools to facilitate further analysis, reverse engineering, or credential harvesting on a compromised host.
