[Bug][cyber] Defensive SIEM rule-override tuning and benign agent binary RE wrongly blocked as cyber (req_011CcGsa9Rmd555hKJSXBc5x)

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

Why this is a false positive

The flagged session is routine defensive security operations: tuning SIEM detection rules to correctly override built-in authentication-event signatures, reviewing syslog telemetry for blocked login retries, and reverse-engineering a locally-held vendor connector binary to document its network behavior. All of this is blue-team work on systems within the operator's own authorized scope, using the binary and logs already in hand — there is no exploitation, targeting of third parties, or offensive capability involved. The classifier appears to be keying on generic security vocabulary (binary unpacking, retries, connector comms) rather than any actual malicious intent or action, producing a false positive that blocks standard detection-engineering and incident-analysis tasks.
