AI cryptanalysis could either compromise existing algorithms or validate their security through rigorous testing during the post-quantum migration phase.
Anthropic has used Claude Mythos to develop a practically inapplicable but academically relevant attack on AES variants and an improved attack on the post-quantum candidate Hawk.
CISOs must now begin inventorying their encryption landscapes for post-quantum cryptography and establish migration plans before standardized quantum-secure algorithms must be implemented across the board.
Quantum computers threaten encrypted data stored today retroactively; credentials are the most critical attack target and should take priority in migration paths to post-quantum cryptography.
In the DACH region, only 8.5 percent of SSH servers are quantum-resistant; new Forescout dashboards enable CISOs to systematically assess and prioritize quantum migration backlogs.
Only 5% of CISOs prioritize the “Harvest Now, Decrypt Later” threat despite second-highest concern about quantum computing, while standards for quantum-resistant encryption are available from 2024.
