Claude Opus 4.6 Blocking Legitimate Cybersecurity Research — Paid Max Users Hit Safety Friction

r/ClaudeAI·medium signal

A Claude x5/x20 Max subscriber since early 2025 reports Opus 4.6 suddenly blocking legitimate cybersecurity work including static analysis, decompilation, and CWE-based auditing (151 upvotes, 37 comments). Multiple commenters confirm similar blocks on security research workflows. Anthropic's own docs acknowledge the new enforcement pipelines 'will create friction for legitimate security research,' but the community reports the false positive rate exceeds what's workable for professional use.
