In this article published on Computable, Anthropic&#8217;s Claude Mythos Preview is presented as a model capable of autonomously finding and exploiting software vulnerabilities at a scale and speed no human can match \u2014 including flaws undetected for decades. Deemed too dangerous for public release, it is being made available exclusively to select technology companies via Project Glasswing. Rewire AI security expert Nanne van &#8216;t Klooster warns that the model signals a fundamental shift: organisations must now deploy their own AI-driven security agents to keep pace with threats that operate continuously \u2014 while ensuring humans remain in the loop.<\/p>\n\n\n\n<p><strong><a class=\"\" href=\"https:\/\/www.computable.nl\/2026\/04\/09\/anthropic-houdt-hackmodel-mythos-bewust-achter-slot-en-grendel\/\" target=\"_blank\" rel=\"noreferrer noopener\">Read the full article in Computable [in Dutch]<\/a><\/strong>.<\/p>\n<\/div>\n<\/div>\n\n\r\n    <\/div>\r\n<\/section><\/div>\n<\/div>\n<\/div><\/div>\n","protected":false},"featured_media":12804,"template":"","class_list":["post-12740","press","type-press","status-publish","has-post-thumbnail","hentry"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v22.3 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>Anthropic deliberately keeps its model Mythos under lock and key | Rewire | Data &amp;
