CRITICAL E006: Malicious code pattern detected in skill scripts.

• Malicious code pattern detected (high risk: 1.00). This content is an explicit offensive cryptanalysis playbook with runnable code and tool commands for exploiting symmetric crypto (padding oracles, CBC bit-flipping, ECB byte-at-a-time, two-time-pad, LFSR/MT state recovery, GCM nonce-reuse forgery, etc.), enabling unauthorized decryption, key/state recovery, and tag forgery.
