Skill Claude CodeCodex
A method for recovering an unknown encryption, signing, or encoding algorithm from an ARM64 execution trace, which is a recorded sequence of processor operations. It uses evidence from the trace and checks possible algorithms against the observed results.

Strong activation entry for AlgoKiller ciphertext-recovery mode. Bind an ARM64 trace, force-load the ciphertext-recovery methodology, and start cipher / algorithm recovery from a target ciphertext.
Skill Claude CodeCodex
A method for analyzing ARM64 execution traces, which are detailed records of processor instructions and program activity. It uses a bound trace file and evidence from trace-analysis tools to study execution flow, fields, calls, and data buffers.
Skill Claude CodeCodex
Analyzes encryption algorithms, key management, and file encryption routines used by ransomware families to assess decryption feasibility, identify implementation weaknesses, and support recovery efforts. Covers AES, RSA, ChaCha20, and hybrid encryption schemes. Activates for requests involving ransomware…
