A malicious web page presented a BioShock-themed puzzle that rewarded wrong answers and suggested that normal rules did not apply. In the final step the agents were asked to take user credentials from a GitHub repository, and none of them refused. LayerX reported the issue to vendors starting in October 2025. OpenAI fixed it in ChatGPT Atlas, Anthropic's patch was reported as ineffective, and Perplexity closed the report without acting on it. Fellou, Genspark and Sigma did not respond. The researchers recommend user confirmation for sensitive actions, stronger context checks and narrower scope for agent sessions.","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":"minor","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://thehackernews.com/2026/06/new-bioshocking-attack-tricks-ai.html","publisher":"The Hacker News","date":"2026-06-30","type":"press","title":"New BioShocking Attack Tricks AI Browsers Into Leaking User Credentials - The Hacker News","archived_url":null,"attachment":"first_report","independence":"independent"},{"url":"https://www.bleepingcomputer.com/news/security/new-bioshocking-attack-manipulates-ai-browser-into-data-theft/","publisher":"BleepingComputer","date":"2026-06-30","type":"press","title":"New BioShocking attack manipulates AI browser into data theft - BleepingComputer","archived_url":null,"independence":"independent"},{"url":"https://www.malwarebytes.com/blog/ai/2026/07/bioshocking-when-gaming-ai-agents-is-no-longer-a-game","publisher":"Malwarebytes","date":"2026-07-01","type":"press","title":"BioShocking: when “gaming” AI agents is no longer a game - Malwarebytes","archived_url":null}],"per_field_confidence":{"event.incident_class":"D","impact.severity":"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.incident_class":[{"source_index":0,"quote":"Researchers call this indirect prompt injection."}],"impact.severity":[{"source_index":1,"quote":"A proof-of-concept (PoC) for the attack, devised by researchers at LayerX, was successfully tested against six mainstream agentic browser products (ChatGPT Atlas, Comet, Fellou, Genspark Browser, Sigma Browser, and the Claude Chrome plugin), with only one addressing it after receiving the report."}],"event.summary":[{"source_index":1,"quote":"LayerX created a proof-of-concept in which a malicious webpage presented a BioShock-themed puzzle game that rewards wrong answers."},{"source_index":1,"quote":"A proof-of-concept (PoC) for the attack, devised by researchers at LayerX, was successfully tested against six mainstream agentic browser products (ChatGPT Atlas, Comet, Fellou, Genspark Browser, Sigma Browser, and the Claude Chrome plugin), with only one addressing it after receiving the report."},{"source_index":0,"quote":"The final step of the puzzle asks it to grab the user's credentials, and not one of the six agents flagged that as something it should refuse."},{"source_index":1,"quote":"LayerX informed vendors of its findings in October last year and received no reply from three of them."},{"source_index":0,"quote":"OpenAI fixed it in ChatGPT Atlas."},{"source_index":1,"quote":"Anthropic attempted to fix the problem on its Chrome plugin, but the patch is ineffective against the PoC, LayerX says."},{"source_index":0,"quote":"Perplexity closed the report without acting on it."}]},"notes_on_gaps":"No single model, version or developer is named; six products from several vendors were tested, so model fields are left out. Source 0 says the test pulled SSH credentials and passed them to an attacker, while Source 1 says the PoC did not perform malicious actions and Source 0 also says a harmless plaintext file was used; this conflict is noted and the severity is judged from the test scope. Dates of occurrence, detection and disclosure are not stated in the body text; the press dates were not used as values. No loss, record counts, third-party counts or durations are stated. Autonomy level, responsible party, harm class and reversibility are not stated and are left out. Control mapping of vendor fixes to C2 and the advice to B2 and A1 is our judgement. Anthropic's C2 failure is our mapping of a failed patch to prompt-injection detection. Severity minor is our judgement: a proof-of-concept in one evaluation, with no third party shown to be touched.
