{
  "summary": "Reviewed `aws-lc/crypto/fipsmodule/ml_kem/ml_kem.h`, which is a plain C header exposing ML-KEM size constants and function prototypes for keypair, encapsulation, and decapsulation. I found no concrete indicators of install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, hidden subprocess execution, or persistence in this target file.\nReviewed this Perl generator for the x86_64 RDRAND assembly path. It only emits local assembly text and pipes it to the bundled `x86_64-xlate.pl` helper; I found no concrete indicators of install hooks, network/exfiltration, credential access, dynamic code loading from untrusted sources, obfuscation, or persistence in this file.\nReviewed `aws-lc/util/fipstools/acvp/acvptool/testmodulewrapper/hmac_drbg_test.go`, which is a deterministic Go unit test for HMAC-DRBG vector validation plus a hex-decoding helper. I checked for install-time hooks, network or exfiltration paths, credential access, dynamic code loading, obfuscation, persistence, and other hidden execution behavior, and found no concrete malicious or supply-chain indicators in this file.\nReviewed `builder/cc_builder/apple_aarch64.rs`, which is a static list of Apple AArch64/AWS-LC source paths used to assemble the crypto library. 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, or persistence behavior.\nReviewed `builder/cc_builder/linux_aarch64.rs`, which is a static Rust constant enumerating Linux/aarch64 assembly source paths for the crypto build. I found no concrete indicators of install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, or persistence in this file.",
