Teams run each website in a separate process sandbox.<\/p>\n<p>However, no layer is impenetrable, Holley noted, and attackers combine bugs in the rendering code with bugs in the sandboxes in an attempt to gain privileged access. While his team has now adopted a more secure programming language, Rust, the developers can\u2019t afford to stop and rewrite the decades\u2019 worth of existing C++ code, \u201cespecially since Rust only mitigates certain, (very common) classes of vulnerabilities.\u201d<\/p>\n<p>While automated analysis techniques like fuzzing, which uncovers vulnerabilities or bugs in source code, are useful, some bits of code are more difficult to fuzz than others, \u201cleading to uneven coverage,\u201d Holley pointed out. Human teams can find bugs that AI can\u2019t by reasoning through source code, but this is time-consuming, and is bottlenecked due to limited human resources.<\/p>\n<p><a href=\"https:\/\/www.csoonline.com\/article\/4162259\/claude-mythos-signals-a-new-era-in-ai-driven-security-finding-271-flaws-in-firefox.html\">Source<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Claude Mythos signals a new era in AI-driven security, finding 271 flaws in Firefox https:\/\/www.csoonline.com\/article\/4162259\/claude-mythos-signals-a-new-era-in-ai-driven-security-finding-271-flaws-in-firefox.html&#8230;<\/p>\n","protected":false},"author":1,"featured_media":234754,"comment_status":"closed","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"fifu_image_url":"https:\/\/www.csoonline.com\/wp-content\/uploads\/2026\/04\/4162259-0-73862800-1776907583-firefox-100962826-orig.jpg?quality=50&strip=all&w=1024","fifu_image_alt":"","footnotes":""},"categories":[15],"tags":[26],"class_list":["post-234753","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-cybersecurity","tag-ai"],"_links":{"self":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/234753"}],"collection":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/comments?post=234753"}],"version-history":[{"count":1,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/234753\/revisions"}],"predecessor-version":[{"id":234755,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/234753\/revisions\/234755"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/media\/234754"}],"wp:attachment":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/media?parent=234753"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/categories?post=234753"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/tags?post=234753"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
