The AI assisted researchers in finding vulnerabilities in cryptographic systems that would otherwise require substantial manual analysis effort. ## Content Anthropic has published new research showing that Claude can help identify weaknesses in cryptographic algorithms — the mathematical methods used to keep data private. The work was done using Claude Mythos Preview, an internal research model. According to Anthropic, it helped their researchers find vulnerabilities in cryptographic systems that would typically require significant manual analysis. The full details are available in Anthropic's research publication. --- Tags: [#ai](https://daily.dev/tags/ai), [#security](https://daily.dev/tags/security), [#claude](https://daily.dev/tags/claude), [#cryptography](https://daily.dev/tags/cryptography), [#anthropic](https://daily.dev/tags/anthropic) [View this post on daily.dev](https://daily.dev/posts/anthropic-uses-claude-to-find-weaknesses-in-cryptographic-algorithms-nxasnemue) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Anthropic uses Claude to find weaknesses in cryptographic algorithms","url":"https://daily.dev/posts/anthropic-uses-claude-to-find-weaknesses-in-cryptographic-algorithms-nxasnemue","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/anthropic-uses-claude-to-find-weaknesses-in-cryptographic-algorithms-nxasnemue"},"datePublished":"2026-07-28T19:29:02.180Z","dateModified":"2026-07-28T19:29:32.950Z","description":"Anthropic has published research demonstrating that Claude, specifically an internal model called Claude Mythos Preview, can identify weaknesses in...","isAccessibleForFree":true,"articleSection":"Collections","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"Collections","logo":"https://media.daily.dev/image/upload/s--fk_6ycEi--/f_auto,q_auto/v1780996001/logos/collections?_a=BAMAMiWQ0","url":"https://daily.dev/sources/collections"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/anthropic-uses-claude-to-find-weaknesses-in-cryptographic-algorithms-nxasnemue","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"ai,security,claude,cryptography,anthropic","timeRequired":"PT1M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"Collections","item":"https://daily.dev/sources/collections"},{"@type":"ListItem","position":3,"name":"Anthropic uses Claude to find weaknesses in cryptographic algorithms"}]} ```
