      "summary": "Reviewed `aws-lc/crypto/rand_extra/windows.c`, which implements Windows system-random generation by calling `BCryptGenRandom` on older/UWP paths and lazily loading `bcryptprimitives.dll` to resolve `ProcessPrng` on newer desktop Windows. I checked for install hooks, network or exfiltration behavior, credential access, obfuscation, persistence, and other hidden payload execution, and found no concrete malicious or supply-chain indicators in this file.",
