{
  "summary": "Reviewed the Perl perlasm generator in `aws-lc/crypto/fipsmodule/bn/asm/armv4-mont.pl`, which emits ARMv4/NEON Montgomery-multiplication assembly for `bn_mul_mont_nohw`/`bn_mul8x_mont_neon`. I found no concrete malicious or supply-chain indicators in the target file: no install hooks, network/exfiltration, credential access, hidden downloads, persistence, or obfuscation beyond normal local code-generation logic.",
