Lazarus Hackers Deploy Post-Quantum Encryption for Malware Delivery The Lazarus hacking group has embedded ML-KEM-1024, a NIST-approved post-quantum encryption mechanism, into its malware delivery to make the attacks harder to detect and to future-proof them against advanced security systems. The technique applies quantum-resistant cryptography to conceal malicious activity from defenders. The Lazarus hackers are taking malware delivery to the next level by using post-quantum encryption, a cutting-edge technique that makes it extremely difficult to detect their malicious activities. By embedding ML-KEM-1024, a NIST-approved mechanism, into their malware, they're future-proofing their attacks against even the most advanced security systems.
