[Bug][cyber] Safety block halted SIEM detection-rule tuning (rule-ID overrides) and authorized malware unpacki (req_011CcGsbWfEsdYgBd1wPMGBi)

Type: Cybersecurity safety-filter false positive · Work domain (heuristic): general

Why this is a false positive

This request was a defensive security task on systems the operator owns and administers: tuning SIEM detection rules to correctly classify authentication and login events, and reverse-engineering a packaged binary flagged on the network to map its communications. No offensive capability, target selection, or attack technique was involved—the message describes diagnosing why custom detection-rule overrides failed to attach and unpacking a suspect executable for analysis, both standard SOC and incident-response activities. The cybersecurity classifier appears to have keyed on routine analysis vocabulary (rule IDs, binary unpacking, comms mapping) without distinguishing defensive triage from offensive intent.
