{
  "summary": "Reviewed aws-lc/crypto/fipsmodule/ml_kem/mlkem/debug.c, which only contains MLKEM_DEBUG-only assertion and bounds-check helpers that print to stderr and exit on failure, plus an empty translation-unit fallback when debugging is disabled. I found no concrete indicators of install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain compromise behavior in this file.\nReviewed the Perl assembly generator for `CRYPTO_rdrand_multiple8`, which emits x86_64 assembly through the local `x86_64-xlate.pl` helper and performs only CPU RDRAND-based random generation logic. I found no concrete indicators of install-time hooks, network or exfiltration behavior, credential access, dynamic remote code loading, obfuscation, or persistence in this target file.\nReviewed `aws-lc/crypto/fipsmodule/rand/internal.h`, which is a C header defining CTR-DRBG state, reseed constants, and internal RAND test/helper declarations. I found no concrete indicators of install-time execution, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain compromise behavior in this file.\nReviewed `aws-lc/crypto/test/x509_util.cc`, which contains a test helper for building certificate/CRL stacks and running `X509_verify_cert` with an optional callback. I found no concrete indicators of install-time execution, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain compromise behavior in this file.\nReviewed `aws-lc/crypto/ube/internal.h`, which is a small internal AWS-LC header declaring UBE generation-number APIs and test-only toggles. I checked for install hooks, hidden execution, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, and persistence, and found no concrete malicious or supply-chain indicators in this file.",
