The post Here’s what Anthropic found when it turned Mythos loose on encryption algorithms appeared first on CyberScoop.","Anthropic's AI model, Claude Mythos, has identified new mathematical weaknesses in two cryptographic methods: HAWK, a post-quantum candidate, and a simplified version of AES. While these flaws are considered substantial research advancements, Anthropic emphasizes they do not affect currently deployed software, as the attacks are theoretical and require impossible amounts of data or target simplified versions of the algorithms.","AI model Claude Mythos discovers mathematical weaknesses in post-quantum encryption candidate and AES.","https:\u002F\u002Fcyberscoop.com\u002Fanthropic-claude-mythos-encryption-flaws-hawk-aes-pqc\u002F","https:\u002F\u002Fcyberscoop.com\u002Fwp-content\u002Fuploads\u002Fsites\u002F3\u002F2026\u002F07\u002FGettyImages-2263903662.jpg","2026-07-28T20:54:49+00:00","2026-07-28T22:00:18.47276+00:00",8,[17,20,23,26,28,30],{"name":18,"type":19},"Claude Mythos","product",{"name":21,"type":22},"Anthropic","vendor",{"name":24,"type":25},"AES","technology",{"name":27,"type":25},"Post-quantum cryptography",{"name":29,"type":19},"HAWK",{"name":31,"type":25},"AI","0493c7e9-989a-4692-b4e6-136f5ec09675",{"id":32,"icon":34,"name":35,"slug":36},null,"Cryptography","cryptography",[38,43,48],{"category":39},{"id":40,"icon":34,"name":41,"slug":42},"80544778-fabb-4dcd-aa35-17492e5dcf4f","Vulnerabilities","vulnerabilities",{"category":44},{"id":45,"icon":34,"name":46,"slug":47},"839da5c1-3c34-47e2-9499-f7201640e3ac","AI Security","ai-security",{"category":49},{"id":50,"icon":34,"name":51,"slug":52},"e7b231c8-5f79-4465-8d38-1ef13aea5a14","Threat Intelligence","threat-intelligence",[],[21,18,29],{"controls":56,"vendors":112},[57,86],{"slug":58,"name":59,"problem":60,"products":61},"vulnerability-management","Vulnerability scanning and prioritisation","You know which systems are vulnerable, and which ones to fix first.",[62,70,78],{"vendor_slug":63,"vendor_name":64,"vendor_logo":65,"product_slug":66,"product_name":67,"url":68,"description":69},"holm-security","Holm Security","\u002Fvendor-logos\u002Fholm-security.png","holm-security-platform","Holm Security Platform","https:\u002F\u002Fwww.holmsecurity.com\u002F","Vulnerability scanning of systems, web applications, cloud and the external attack surface, plus phishing simulation.",{"vendor_slug":71,"vendor_name":72,"vendor_logo":73,"product_slug":74,"product_name":75,"url":76,"description":77},"tenable","Tenable","\u002Fvendor-logos\u002Ftenable.png","tenable-vulnerability-management","Tenable Vulnerability Management","https:\u002F\u002Fwww.tenable.com\u002Fproducts\u002Fvulnerability-management","Cloud-based vulnerability scanning and prioritisation, built on Nessus.",{"vendor_slug":79,"vendor_name":80,"vendor_logo":81,"product_slug":82,"product_name":83,"url":84,"description":85},"rapid7","Rapid7","\u002Fvendor-logos\u002Frapid7.png","insightvm","Rapid7 Exposure Command (InsightVM)","https:\u002F\u002Fwww.rapid7.com\u002Fproducts\u002Finsightvm\u002F","Vulnerability scanning and risk-based prioritisation; InsightVM is now part of Exposure Command, alongside attack surface and cloud risk.",{"slug":87,"name":88,"problem":89,"products":90},"encryption-key-management","Encryption and key management","Stolen data stays unreadable, and the keys stay under your control.",[91,99,104],{"vendor_slug":92,"vendor_name":93,"vendor_logo":94,"product_slug":95,"product_name":96,"url":97,"description":98},"thales","Thales","\u002Fvendor-logos\u002Fthales.png","luna-hsm","Thales Luna HSM","https:\u002F\u002Fcpl.thalesgroup.com\u002Fencryption\u002Fhardware-security-modules","Hardware security modules for protecting cryptographic keys.",{"vendor_slug":92,"vendor_name":93,"vendor_logo":94,"product_slug":100,"product_name":101,"url":102,"description":103},"ciphertrust","CipherTrust Data Security Platform","https:\u002F\u002Fcpl.thalesgroup.com\u002Fencryption\u002Fdata-security-platform","Data discovery, encryption and central key management across on-premises and cloud.",{"vendor_slug":105,"vendor_name":106,"vendor_logo":107,"product_slug":108,"product_name":109,"url":110,"description":111},"utimaco","Utimaco","\u002Fvendor-logos\u002Futimaco.png","utimaco-hsm","Utimaco General Purpose HSM","https:\u002F\u002Futimaco.com\u002Fdata-protection\u002Fgp-hsm","Hardware security modules for key generation, storage and cryptographic operations.",[],{"slug":114,"title":115,"body":116,"framework_refs":117,"framework_notes":126},"ai-uncovers-theoretical-cryptographic-weaknesses-in-post-quantum-algorithms","AI Uncovers Theoretical Cryptographic Weaknesses in Post-Quantum Algorithms","Anthropic's Claude Mythos AI identified mathematical weaknesses in HAWK, a post-quantum cryptographic candidate, and a simplified AES variant, representing a significant advancement in AI-assisted cryptographic research.
