Review rev_7ab99664cbb34461b92093ea0ff18ec4

{
  "summary": "Reviewed `aws-lc/util/fipstools/acvp/acvptool/subprocess/kda.go`, which only unmarshals a JSON `mode` field and dispatches to a mode-specific `ProcessKDA` handler from an in-memory map. I found no concrete malicious or supply-chain indicators in this file: no install hooks, network or exfiltration code, credential access, dynamic code loading, obfuscation, or persistence behavior.\nReviewed `aws-lc/crypto/dilithium/pqcrystals_dilithium_ref_common/config.h`, which is a small preprocessor configuration header selecting Dilithium mode namespacing macros for BoringSSL/AWS-LC. I checked for install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence, and other supply-chain indicators, and found no concrete malicious or suspicious behavior in this file.\nReviewed `aws-lc/crypto/fipsmodule/ml_kem/ml_kem_ref/symmetric.h`, which is a small C header that only declares Kyber-related SHAKE/PRF helper functions and maps them through simple macro aliases to SHA3 primitives. I found no concrete malicious or supply-chain indicators in this file: no install hooks, network or exfiltration code, credential access, dynamic code loading, obfuscation, persistence, or hidden subprocess execution.\nReviewed this header, which only declares a testing-only custom randombytes API and does not itself contain executable logic. I checked for install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence tampering, and other hidden payload behavior, and found no concrete malicious or supply-chain indicators in the file.\nReviewed `builder/cc_builder/win_x86_64.rs`, which is a static Rust constant listing Windows x86_64 assembly source paths for the crypto library. I found no concrete indicators of install-time execution, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence in this file.",
