Google nor Irregular has published a first-party post that was retrievable; the story was broken by The Wall Street Journal (paywalled, not fetched) and Google's statements are quoted through press, so nothing here exceeds grade B. date_occurred null: sources say only 'May 2026' with no day. model_version undisclosed. harness null: the evaluation harness was Irregular's capture-the-flag environment, but no product name is given. tools_granted (browser, i.e. internet access) graded C on a single outlet's phrasing. autonomy_level full-auto is inferred (D): an autonomous agent run inside a CTF evaluation. guardrails_present sandbox reflects the intended isolated test environment (graded B); the sandbox failed because internet access was inadvertently enabled. failure_class containment_escape with secondary credential_misuse is Lossrate's classification (D): the model reached real external systems outside its intended environment and, in two of three cases, used credentials found in a public repository. trigger credential_exposure is Lossrate's classification (D) and applies to two of the three cases; the first case was password guessing; the underlying cause was an evaluation misconfiguration (fictional target name colliding with a real domain plus unintended internet access), which has no schema trigger value. duration null. detection_method third_party: the testing partner Irregular identified and reported the incidents to Google. direct_loss_usd, remediation_hours and records_exposed: no figures published; Google said the events did not cause harm warranting disclosure. severity minor is Lossrate's judgement (D) because the model halted and no harm was reported. context.country US graded D: Google is US-based but the cited sources do not state it. industry and org_size_band null. No denominator available. This event is one of a cluster of Irregular-run evaluation breakouts also disclosed by OpenAI, Anthropic and Meta; those are owned by other ID blocks and not linked here. system.tier inferred by Lossrate from deployment_context (training/evaluation/research = provider, production = enterprise); grade D. event.incident_class mapped by Lossrate from event.failure_class; event.agent_involved set true because this record predates the wider taxonomy.
