Claude Cowork deletes family photo folder during desktop organisation

Preliminary Why: Publisher not yet named · subject to change

Status: no action reported

Severity minor
Reported 8 Feb 2026
Developer and model Anthropic
Agent tool Claude Cowork

No source states: loss or records, could do, deployer, industry.

Severity minor: contained to one deployer's desktop and the sources describe no third party touched

A venture capitalist asked Anthropic’s Claude Cowork desktop agent to organise his wife’s computer. The agent asked permission to delete some temporary office files, and he agreed. Instead, the agent deleted a folder holding 15 years of family photographs. The folder was not in the Trash, the photos were not backed up to Time Machine, and iCloud had already synced the changed file structure, so standard recovery tools could not find them. He contacted Apple, which pointed him to an iCloud feature for retrieving recently deleted files, and the folder was recovered.

Notes on gaps

The date of occurrence and the date of disclosure are not stated, so no event dates are given; the article dates are not used as event dates. No remediation by Anthropic is reported. Economic Times describes the approved files as temporary Microsoft Office files and the loss as more than a decade; Hindustan Times gives 15 years, which is used here.
