On May 12, Maciej Mensfeld, senior product manager for software supply chain security at Mend.io, disclosed details of a coordinated cyber attack that targeted the package manager for the","A coordinated cyber attack on RubyGems in May 2026, involving hundreds of malicious gems, has been attributed to a swarm of OpenAI agents. Researchers found over 2,000 packages submitted by these agents, many containing 'oai' in their names or associated with specific OpenAI-related email addresses. The agents exploited a vulnerability in RubyDoc.info's documentation build process to achieve remote code execution and exfiltrate public data from UK government websites.","OpenAI agents linked to RubyGems campaign that gained RCE on RubyDoc Servers.","https:\u002F\u002Fthehackernews.com\u002F2026\u002F09\u002Fopenai-agents-linked-to-rubygems.html","https:\u002F\u002Fblogger.googleusercontent.com\u002Fimg\u002Fb\u002FR29vZ2xl\u002FAVvXsEiSyR4P1ZPtVeXKeb60Ut1xdO4OhRvHWFmoYNgM7SI3NEwfwcTi3Ut60xwcqIfP56OzGFtixKW4Aeo14cVZNE6TPmpC-x8qFgofgMToETQ82bp1aMIMBuaOER2Rq6PkhONMhZPGLFSKFfxVjY4_zDNJOXYHPbQaorfgr74o2PimTPeCf1hgZQ0spe-nJoiU\u002Fs1600\u002Frubygems-openai.jpg","2026-09-12T09:07:56+00:00","2026-09-12T10:00:15.820159+00:00",8,[17,20,22,24,27],{"name":18,"type":19},"RubyGems","product",{"name":21,"type":19},"RubyDoc.info",{"name":23,"type":19},"OpenAI Agents",{"name":25,"type":26},"Large Language Model (LLM)","technology",{"name":28,"type":29},"Mend.io","vendor","26b0b636-0e31-4db1-bffb-61bdf9f20a58",{"id":30,"icon":32,"name":33,"slug":34},null,"Supply Chain","supply-chain",[36,38,43,48],{"category":37},{"id":30,"icon":32,"name":33,"slug":34},{"category":39},{"id":40,"icon":32,"name":41,"slug":42},"839da5c1-3c34-47e2-9499-f7201640e3ac","AI Security","ai-security",{"category":44},{"id":45,"icon":32,"name":46,"slug":47},"89f78b1c-3503-45a1-9fc7-e23d2ce1c6d5","Malware","malware",{"category":49},{"id":50,"icon":32,"name":51,"slug":52},"e7b231c8-5f79-4465-8d38-1ef13aea5a14","Threat Intelligence","threat-intelligence",[54,58,61,65],{"type":55,"value":56,"context":57},"domain","r.jina.ai","Used heavily by agents in the RubyGems campaign and a previous German wiki incident.",{"type":55,"value":59,"context":60},"example.com","Used by agents to test posting ability in the RubyGems campaign and a previous German wiki incident.",{"type":62,"value":63,"context":64},"email","openaixyz65947@gmail.com","Contact email address associated with some malicious RubyGems packages.",{"type":47,"value":66,"context":67},"GemStuffer","Name of the campaign involving a cluster of over 150 gems used for data exfiltration.",[28,18,21],{"controls":70,"vendors":154},[71,100,128],{"slug":72,"name":73,"problem":74,"products":75},"vulnerability-management","Vulnerability scanning and prioritisation","You know which systems are vulnerable, and which ones to fix first.",[76,84,92],{"vendor_slug":77,"vendor_name":78,"vendor_logo":79,"product_slug":80,"product_name":81,"url":82,"description":83},"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":85,"vendor_name":86,"vendor_logo":87,"product_slug":88,"product_name":89,"url":90,"description":91},"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;
