A new ransomware called Kyber claims to use post-quantum cryptography (PQC) to enhance its encryption, specifically employing the ML-KEM algorithm. However, experts suggest this is primarily a marketing tactic aimed at instilling fear in victims, as the actual encryption process relies on established methods like AES-256, which are already considered secure against quantum attacks.
The emergence of ransomware like Kyber using post-quantum cryptography (PQC) is primarily a marketing strategy to intimidate victims rather than an actual technical necessity. As a CISO or cybersecurity expert, this highlights the need to educate decision-makers on the real capabilities and timelines of quantum computing threats, ensuring they don't fall prey to psychological tactics that inflate the urgency or inevitability of paying ransoms.
