With over 500,000 lines of unobfuscated TypeScript exposed, developers and hackers alike have been scrambling to get their hands on the valuable resource. However, as <strong>PCMag<\/strong> reports, hackers are now using the leak as bait to spread malware on GitHub.<\/p>\n<h3>Malware Distribution on GitHub<\/h3>\n<p>According to <em>Zscaler&#8217;s ThreatLabz<\/em>, a malicious GitHub repository has been discovered, disguising itself as a leaked TypeScript source code for Anthropic&#8217;s Claude Code CLI. The repository&#8217;s README falsely claims to offer unlocked enterprise features, but in reality, it contains a Rust-based dropper named ClaudeCode_x64.exe. Upon execution, this dropper installs Vidar, an infostealer that harvests account credentials, credit card data, and browser history, along with GhostSocks, which creates a proxy network for malicious activities.<\/p>\n<h2>Impact of the Leak<\/h2>\n<p>The leak has significant implications for Anthropic, as it pulls back the curtains on its flagship product, Claude Code. As <strong>SC Media<\/strong> notes, the exposure of the source code could be a major blow to the company, as it reveals valuable information about the tool&#8217;s inner workings. Furthermore, the leak has created an opportunity for threat actors to deliver malware to unsuspecting users, as reported by <em>BleepingComputer<\/em>.<\/p>\n<h3>Practical Takeaways<\/h3>\n<p>To avoid falling victim to these malware campaigns, users should exercise caution when searching for the Claude Code leak on GitHub. It is essential to verify the authenticity of the repository and the files being downloaded. Additionally, users should keep their antivirus software up to date and be wary of any suspicious activity on their systems.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Introduction to the Claude Code Leak The recent leak of Anthropic&#8217;s Claude Code [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":2625,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[871,1506,1508,1507,1510,1509],"class_list":["post-2626","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-blog","tag-anthropic","tag-claude-code","tag-ghostsocks","tag-github","tag-malware","tag-vidar"],"_links":{"self":[{"href":"https:\/\/casi.live\/blog\/wp-json\/wp\/v2\/posts\/2626","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/casi.live\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/casi.live\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/casi.live\/blog\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/casi.live\/blog\/wp-json\/wp\/v2\/comments?post=2626"}],"version-history":[{"count":0,"href":"https:\/\/casi.live\/blog\/wp-json\/wp\/v2\/posts\/2626\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/casi.live\/blog\/wp-json\/wp\/v2\/media\/2625"}],"wp:attachment":[{"href":"https:\/\/casi.live\/blog\/wp-json\/wp\/v2\/media?parent=2626"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/casi.live\/blog\/wp-json\/wp\/v2\/categories?post=2626"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/casi.live\/blog\/wp-json\/wp\/v2\/tags?post=2626"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
