{
  "summary": "Reviewed `aws-lc/crypto/bio/bio_mem.c`, which implements the in-memory BIO methods and buffer control/read/write logic for AWS-LC. I checked for install-time hooks, hidden subprocesses, network or credential access, dynamic code loading, obfuscation/deobfuscation, and persistence tampering, and found no concrete malicious or supply-chain indicators in this file.\nReviewed aws-lc/crypto/fipsmodule/ec/p256.c, which implements P-256 field and point arithmetic plus EC_METHOD wiring for BoringSSL/AWS-LC. I checked for install hooks, hidden subprocess execution, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, and other supply-chain indicators; none were present in this target file.\n`aws-lc/crypto/perlasm/x86asm.pl` is a Perl assembler-macro helper used to emit x86 assembly and select local backend generators for different targets. I reviewed it for install-time execution, hidden subprocesses, network/exfiltration, credential access, dynamic code loading, obfuscation, and persistence behavior, and found no concrete malicious or supply-chain indicators in this file.",
