In a first, a ransomware family is confirmed to be quantum-safe

Kyber ransomware claimed to use quantum-safe ML-KEM encryption, but Rapid7 found it actually wraps AES keys with RSA-4096.

Researchers say the “quantum-safe” branding is likely a scare tactic aimed at intimidating victims, not a real technical advantage.

The case shows attackers are borrowing post-quantum cryptography language while relying on conventional ransomware methods underneath.

For victims, the immediate threat remains data encryption and extortion—not quantum computers or Shor’s algorithm.
