The system estimated the source to within about 40cm, which led to an old carbon monoxide detector needing new batteries. The approach builds on BeepBeep, a 2007 acoustic ranging paper by Peng, Shen, Zhang, Li and Tan.","solution":"N/A -- no mitigation discussed in source.","labels":["industry","research"],"sourceUrl":"https://simonwillison.net/2026/Nov/9/mysterious-beeps/","publishedAt":"2026-11-09T23:57:21.000Z","cveId":null,"cweIds":null,"cvssScore":null,"cvssSeverity":null,"severity":"info","attackType":[],"issueType":"news","affectedPackages":null,"affectedPackageNames":null,"affectedPackageRefs":null,"affectedVendors":["Anthropic"],"affectedVendorsRaw":["Claude","Claude Code","Opus 5.5"],"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":"2026-11-09T23:57:21.000Z","fixReleasedAt":null,"daysToFix":null,"fixCheckedAt":null,"capecIds":null,"crossRefCount":0,"attackSophistication":"trivial","impactType":null,"aiComponentTargeted":null,"llmSpecific":true,"classifierConfidence":0.62,"researchCategory":null,"atlasIds":null}}
