Quantum-Safe Code Auditing: LLM-Assisted Static Analysis and Quantum-Aware Risk Scoring for Post-Quantum Cryptography Migration

The impending arrival of cryptographically relevant quantum computers CRQCs threatens the security foundations of modern software: Shor's algorithm breaks RSA, ECDSA, ECDH, and Diffie-Hellman, while Grover's algorithm reduces the effective security of symmetric and hash-based schemes. Despite NIS...

ThreatsDay Bulletin: PQC Push, AI Vuln Hunting, Pirated Traps, Phishing Kits & 20 More Stories

Some weeks in security feel loud. This one feels sneaky. Less big dramatic fireworks, more of that slow creeping sense that too many people are getting way too comfortable abusing things they probably shouldn’t even be touching. There’s a little bit of everything in this one, too. Weird delivery...
