The migration was run with Terraform. A key state file was missing, so duplicate resources were created when the task was stopped midway. After the file was uploaded, the agent issued a terraform destroy command that removed the existing infrastructure, including a shared database with 2.5 years of course records and the backup snapshots. Amazon Business support restored the data after about a day. The developer said he would now manually review commands that could delete or modify production systems, and acknowledged he had over-relied on the agent.","tags":[],"date_detected":null,"near_miss":null,"root_cause":null,"root_cause_detail":null,"failure_class_detail":null,"responsible_party":null,"adversarial_actor":null,"input_provenance":null,"time_to_contain":null,"operations_paused":null,"remediation":null,"precursor_events":null},"impact":{"direct_loss_usd":null,"remediation_hours":null,"records_exposed":null,"third_parties_affected_count":null,"severity":"moderate","severity_because":"Test: data of others touched with bounded scope stated; the shared course database held 2.5 years of submissions","harm_class":[],"affected_description":null,"protected_class_involved":null,"data_categories_exposed":[],"loss_range_usd":null,"reversibility":null,"downstream_exposure_count":null},"evidence":{"sources":[{"url":"https://www.storyboard18.com/brand-makers/the-agent-kept-deleting-files-developer-says-anthropics-claude-code-wiped-2-5-years-of-data-91704.htm","publisher":"Storyboard18","date":"2026-03-10","type":"press","title":"“The agent kept deleting files”: Developer says Anthropic’s Claude Code wiped 2.5 years of data - Storyboard18","archived_url":null,"attachment":"first_report","independence":"independent"},{"url":"https://timesofindia.indiatimes.com/technology/tech-news/i-over-relied-on-ai-developer-says-claude-code-accidentally-wiped-2-5-years-of-data-shares-advice-to-prevent-loss/articleshow/129336313.cms","publisher":"The Times of India","date":"2026-03-11","type":"press","title":"‘I over-relied on AI’: Developer says Claude Code accidentally wiped 2.5 years of data, shares advice to - The Times of India","archived_url":null,"independence":"independent"}],"per_field_confidence":{"event.agent_involved":"C","event.incident_class":"D","impact.severity":"D","impact.severity_because":"D","event.summary":"C","system.autonomy_level":"D","system.deployment_context":"D","event.trigger":"D","event.detection_method":"D","context.country":"D","system.developer":"D","event.date_disclosed":"D","context.denominator_available":"D"},"field_citations":{"event.agent_involved":[{"source_index":0,"quote":"Alexey Grigorev, founder of AI Shipping Labs, said in a Substack post that Anthropic’s AI coding assistant, Claude Code, accidentally removed the production infrastructure of his DataTalks.Club course platform during the migration."}],"event.incident_class":[{"source_index":0,"quote":"Alexey Grigorev, founder of AI Shipping Labs, said in a Substack post that Anthropic’s AI coding assistant, Claude Code, accidentally removed the production infrastructure of his DataTalks.Club course platform during the migration."}],"impact.severity":[{"source_index":0,"quote":"“I was overly reliant on my Claude Code agent, which accidentally wiped all production infrastructure for the DataTalks.Club course management platform that stored data for 2.5 years of all submissions,” Grigorev said."}],"impact.severity_because":[{"source_index":0,"quote":"“I was overly reliant on my Claude Code agent, which accidentally wiped all production infrastructure for the DataTalks.Club course management platform that stored data for 2.5 years of all submissions,” Grigorev said."}],"event.summary":[{"source_index":0,"quote":"The incident happened while Grigorev was trying to move his AI Shipping Labs website to Amazon Web Services (AWS) and run it on the same infrastructure as DataTalks.Club."},{"source_index":0,"quote":"While setting up the migration, a key configuration file that tracks existing infrastructure was missing."},{"source_index":0,"quote":"Instead, the AI issued a “terraform destroy” command that deleted the existing infrastructure before rebuilding it."},{"source_index":0,"quote":"The command shut down both AI Shipping Labs and DataTalks.Club, deleting their shared database containing 2.5 years of course records."},{"source_index":0,"quote":"Grigorev contacted Amazon Business support, which restored the data after about a day."},{"source_index":0,"quote":"Reflecting on the incident, he said he would now manually review any commands that could delete or modify production systems."}]},"notes_on_gaps":"Not stated: exact dates of occurrence and disclosure (only press dates 2026-03-10 and 2026-03-11 given; the Substack original is not quoted directly); model name and version; harness beyond the product name Claude Code; autonomy level; failure class; trigger; detection method beyond the developer discovering the loss; time to contain (the roughly one-day restoration is not a containment time); number of affected students or third parties; direct financial loss (only a $5-10 per month saving is mentioned); country.
