{"data":{"id":"84743c5f-fae9-41be-8e7b-7850b618d3f3","title":"LLMs Generate Predictable Passwords","summary":"Large language models (LLMs, AI systems trained on text data) are very bad at generating passwords because they create predictable patterns instead of truly random ones. The study found that Claude, an LLM, always started passwords with an uppercase G followed by 7, avoided repeating characters, never used the * symbol, and repeated the same password 36% of the time across 50 attempts. This is a serious problem because autonomous AI agents (AI systems that act without human control) will need to create accounts and authenticate themselves, but the passwords they generate are weak and easy to crack.","solution":"N/A -- no mitigation discussed in source.","labels":["safety","security"],"sourceUrl":"https://www.schneier.com/blog/archives/2026/02/llms-generate-predictable-passwords.html","publishedAt":"2026-02-26T12:07:10.000Z","cveId":null,"cweIds":null,"cvssScore":null,"cvssSeverity":null,"severity":"medium","attackType":["other"],"issueType":"news","affectedPackages":null,"affectedVendors":["Anthropic"],"affectedVendorsRaw":["Claude"],"classifierModel":"claude-haiku-4-5-20251001","classifierPromptVersion":"v3","cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":null,"epssScore":null,"patchAvailable":null,"disclosureDate":null,"capecIds":null,"crossRefCount":0,"attackSophistication":"trivial","impactType":["integrity","safety"],"aiComponentTargeted":"inference","llmSpecific":true,"classifierConfidence":0.85,"researchCategory":null,"atlasIds":null}}
