{
  "summary": "Reviewed this ARM assembly implementation of the SHA3 Keccak-f1600 permutation for four parallel states. It consists of straight-line state loads, round-function bitwise operations, and stores only; I found no install-time hooks, network/exfiltration, credential access, dynamic code loading, obfuscation/deobfuscation, persistence, or other supply-chain indicators in the target file.",
