The agent in the study was a sandboxed autonomous agent with web browsing and payment tools and no spending limits, tested against 26 large language models. For the first campaign, four models executed a fraudulent payment after reading hidden page content, while the other models refused or did not follow the injected instructions. The second campaign was a context poisoning attack, which can persist in a retrieval knowledge base once a fraudulent source is misclassified as authoritative. No real funds were used in the testing. The published findings describe a web-content attack with no architectural separation between retrieved content and operator instructions.","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,"primary_risk":"RK01"},"impact":{"direct_loss_usd":null,"remediation_hours":null,"records_exposed":null,"third_parties_affected_count":null,"severity":"minor","severity_because":"Test of minor tier: contained to one sandboxed evaluation and no third party touched, as the source states that no real funds were used.","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.techtimes.com/articles/320039/20260709/hidden-webpage-instructions-are-making-ai-agents-pay-hackers-live-campaigns.htm","publisher":"Tech Times","date":"2026-07-09","type":"press","title":"Hidden Webpage Instructions Are Making AI Agents Pay Hackers in Live Campaigns - Tech Times","archived_url":null,"attachment":"first_report","independence":"independent"}],"per_field_confidence":{"system.tools_granted":"C","event.failure_class":"C","event.trigger":"C","event.detection_method":"C","event.incident_class":"D","impact.severity":"D","impact.severity_because":"D","event.primary_risk":"D","event.summary":"C","system.autonomy_level":"D","system.deployment_context":"D","context.country":"D","system.developer":"D","event.date_disclosed":"D","context.denominator_available":"D"},"field_citations":{"system.tools_granted":[{"source_index":0,"quote":"Zscaler tested both campaigns against 26 large language models using a sandboxed autonomous agent configured with web browsing and payment tools and no spending limits — deliberately maximizing potential exploitation scope."}],"event.failure_class":[{"source_index":0,"quote":"For Campaign 1, four models successfully executed the fraudulent payment: Llama 3.3 70B Instruct, Llama 3.2 90B Vision Instruct, Gemini 3 Flash, and Gemini 2.5 Pro."}],"event.trigger":[{"source_index":0,"quote":"Indirect prompt injection is categorically different: an attacker hides instructions inside third-party content — a webpage, a document, a metadata block — that an AI agent retrieves and processes during a task."}],"event.detection_method":[{"source_index":0,"quote":"On July 2, security researchers at Zscaler ThreatLabz published documentation of two live indirect prompt injection (IPI) campaigns targeting AI agents with financial capabilities."}],"event.incident_class":[{"source_index":0,"quote":"Indirect prompt injection is categorically different: an attacker hides instructions inside third-party content — a webpage, a document, a metadata block — that an AI agent retrieves and processes during a task."}],"impact.severity":[{"source_index":0,"quote":"No real funds were used."}],"impact.severity_because":[{"source_index":0,"quote":"No real funds were used."}],"event.summary":[{"source_index":0,"quote":"Zscaler tested both campaigns against 26 large language models using a sandboxed autonomous agent configured with web browsing and payment tools and no spending limits — deliberately maximizing potential exploitation scope."},{"source_index":0,"quote":"For Campaign 1, four models successfully executed the fraudulent payment: Llama 3.3 70B Instruct, Llama 3.2 90B Vision Instruct, Gemini 3 Flash, and Gemini 2.5 Pro."},{"source_index":0,"quote":"Twenty-two models refused or did not follow the injected instructions."},{"source_index":0,"quote":"This campaign is not primarily a payment attack — it is a context poisoning attack."},{"source_index":0,"quote":"No real funds were used."},{"source_index":0,"quote":"There is no architectural firewall between them."}]},"notes_on_gaps":"Source 0 is one press article summarising a Zscaler report; the Zscaler report itself was not provided. No single model or developer is the implicated system, so model and developer fields are omitted. The testing was sandboxed with no real funds, though the article describes the campaigns as live; deployment_context is set to evaluation on that basis and is a judgement. Autonomy level full-auto is inferred from the absence of any approval prompt, a judgement. Date of occurrence, date of detection, duration, time to contain and direct loss are not stated and are omitted. The May 4 Grok incident is a separate event and is excluded. Responsible party and the wallet and JavaScript details are not recorded as fields. Severity minor is a judgement based on the sandbox test and no third party touched. Controls in the source are described only as recommendations, so no control is recorded as held.
