{
  "summary": "Reviewed `aws-lc/crypto/kyber/pqcrystals_kyber_ref_common/poly.c`, which implements Kyber polynomial serialization, compression/decompression, message conversion, deterministic noise sampling, and NTT-based arithmetic. I checked for install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, and hidden subprocess execution, and found no concrete malicious or supply-chain indicators in this file.\nReviewed `aws-lc/include/openssl/pkcs7.h`, which is a C header exposing PKCS#7 parsing, bundling, signing, and type-checking APIs plus related constants and structs. I found no concrete malicious or supply-chain indicators in this file: no install hooks, network or exfiltration logic, credential access, dynamic code loading, obfuscation/deobfuscation, persistence, or hidden subprocess behavior.\nReviewed aws-lc/crypto/fipsmodule/bn/shift.c, which contains standard BIGNUM bit-shift, bit-test, mask, and low-zero-bit counting routines. I found no concrete indicators of install-time execution, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence in this target file.",
