{"data":{"id":"e1cc6151-5f39-49be-9093-eb3d248bbed7","title":"Google Launches Gemini 4 Argon With Guardrail-Free Access for Vetted Defenders","summary":"Google announced Gemini 4 Argon, a frontier model it is first rolling out to vetted cyber defenders through its Fairwind Program, with Google's own internal teams also using it. Google says it will run Argon without cyber guardrails for trusted defenders and internal teams, and that the model found a critical flaw exposing sensitive personal information across healthcare software, though the announcement does not name the affected software or say whether it has been addressed.","solution":"Google says it is deploying misalignment mitigations that monitor Argon's chain-of-thought and actions and stop execution when necessary, is isolating and sealing sandboxed environments before high-risk training or evaluations, and is designing the model to refuse requests that could enable cyber or CBRN attacks before a wider release.","labels":["security","industry"],"sourceUrl":"https://www.securityweek.com/google-launches-gemini-4-argon-with-guardrail-free-access-for-vetted-defenders/","publishedAt":"2026-10-01T07:52:26.000Z","cveId":null,"cweIds":null,"cvssScore":null,"cvssSeverity":null,"severity":"info","attackType":[],"issueType":"news","affectedPackages":null,"affectedPackageNames":null,"affectedVendors":["Google"],"affectedVendorsRaw":["Gemini 4 Argon","Gemini 3.8 Flash Cyber","CodeMender","Fairwind Program","Wiz","CWE-bench v1","GPT-6 Astra","Grok 4.7"],"classifierModel":"claude-haiku-5-5","classifierPromptVersion":"v4","summaryPromptVersion":"v2","headline":null,"headlinePromptVersion":null,"cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":null,"epssScore":null,"epssCheckedAt":null,"kevDateAdded":null,"advisoryAliases":null,"affectedPackagesSource":null,"affectedPackagesCheckedAt":null,"patchAvailable":null,"disclosureDate":"2026-10-01T07:52:26.000Z","capecIds":null,"crossRefCount":0,"attackSophistication":"moderate","impactType":null,"aiComponentTargeted":null,"llmSpecific":true,"classifierConfidence":0.9,"researchCategory":null,"atlasIds":null}}
