[Bug][cyber] DNS resolver config change blocked: setting LAN DNS to wildcard-respond locally while restricting (req_011CcJpUgS5AA3rKvYfd9kNV)

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

Why this is a false positive

This false positive triggered on a routine network administration task: configuring a local recursive DNS resolver to answer client queries while forwarding all upstream lookups to a single managed DNS provider. This is standard, defensive infrastructure configuration on equipment the operator owns and controls — there is no exploit development, offensive tooling, or unauthorized access involved. The request was flagged solely because it touches DNS and network configuration, which are dual-use topics, not because of any actual malicious intent or content.
