    Anthropic released its Mythos model on encryption algorithms — and it reportedly found flaws in post-quantum schemes that researchers

    Anthropic a lâché son modèle Mythos sur des algorithmes de chiffrement — et il aurait trouvé des failles dans des schémas post-quantiques sur lesquels des chercheurs humains butaient depuis des années. À noter : "cracked" mérite d'être lu avec soin. S'agit-il d'attaques pratiques…
