Anthropic's Claude Mythos Preview discovered improved cryptographic attacks on the HAWK digital signature scheme and a weakened version of AES, with full research papers published. The HAWK attack req…
Anthropic's Claude Mythos Preview model discovered a weakness in the HAWK post-quantum signature scheme in 60 hours, a flaw that two years of human review had missed. The finding highlights AI's poten…
Anthropic's Claude Mythos Preview model improved attacks against two cryptographic algorithms, including the Hawk post-quantum digital signature candidate under NIST evaluation and a weakened version …
Anthropic said an unreleased version of its most powerful model, Claude Mythos Preview, found two previously unknown attacks on crypto algorithms, including one against HAWK, a digital signature syste…
Anthropic recovered a HAWK-256 signing key from a public key in under four hours, but the real threat is a new reduction that halves the dimension of the hard problem for all HAWK instances, pushing H…
Anthropic's Claude Mythos Preview discovered a practical key-recovery attack on the post-quantum HAWK-256 digital signature candidate in roughly 60 hours, reducing effective security from 264 to 238 o…
Anthropic's Claude AI found a key-recovery attack against HAWK-256, a toy parameter set of the post-quantum signature scheme, reducing work factor from 2⁶⁴ to 2³⁸ operations, but the attack exploits a…
Anthropic said its unreleased Claude Mythos Preview model found a previously unknown attack on HAWK, dropping the cost of stealing its smallest key from 2^64 operations to 2^38, and sped up an attack …
Anthropic announced Monday that its Claude Mythos Preview model discovered mathematical weaknesses in two cryptographic algorithms, halving the effective key strength of the post-quantum signature sch…
Anthropic said on July 28 that its controlled-access Claude Mythos Preview model helped researchers improve the best-known attack on HAWK, a post-quantum signature candidate that advanced to the third…
Anthropic's Claude Mythos Preview model found improved attacks against the HAWK post-quantum signature scheme and a reduced-round AES, but verifying the results took researchers nearly a month, highli…
Anthropic's Claude found weaknesses in reduced-round ciphers and the NIST post-quantum candidate HAWK, but full-strength AES-128 remains secure. Each attack cost about $100,000 in API spend and target…
Anthropic's unreleased Claude Mythos Preview model has discovered two cryptanalytic weaknesses: an attack that halves the effective key strength of the post-quantum digital signature scheme HAWK, and …
Anthropic's Claude Mythos AI model autonomously identified vulnerabilities in HAWK, a candidate post-quantum digital signature scheme, in 60 hours—a task that took human cryptographers two years. The …
Google Cloud announced the general availability of quantum-safe digital signatures (ML-DSA, SLH-DSA) and post-quantum key encapsulation (ML-KEM) in Cloud Key Management Service (Cloud KMS), enabling o…
The EU AI Act's high-risk provisions become enforceable on August 2, 2026, but the regulation was written before autonomous AI agents existed, creating a governance gap. Empire Labs Security Division …
Enterprise AI safety certificates such as SOC 2 Type II and ISO 42001 are worthless at runtime because they treat safety as a static design-time product rather than a live execution problem, according…
A developer argues that application logs are structurally inadequate as evidence for disputes involving AI agents, failing tests of integrity, attribution, completeness, and independence. The post con…
AI failures can generate silent flawed outputs that go undetected until an audit or regulatory inquiry, according to Troy Leach, Chief Strategy Officer at the Cloud Security Alliance (CSA), in a piece…
ARC Prize Foundation, a nonprofit advancing open-source AGI research, announced ARC-AGI-3, the world's only unbeaten benchmark measuring agentic intelligence, and launched ARC Prize 2026 with $2,000,0…
