AI Agent Carries Out Multi-Stage Data Theft Attack

Spain's data protection agency reports the country's first agentic AI-powered breach: an AI agent logged in, found vulnerabilities, and modified personal data.

Spain's Agencia Espanola de Proteccion de Datos (AEPD) disclosed on September 14 what it calls the country's first agentic AI-powered personal data breach. An agent using a known language model scanned generic files to log in, then autonomously searched for application vulnerabilities, modified personal data, and accessed invoices. AEPD said the agent was used as an instrument to chain attack phases, implying deliberate use by a threat actor rather than a rogue model. CybaVerse CTO Simon Phillips suggested the actor likely jailbreaked or bypassed the model's guardrails.

Spain's data agency gets first report of AI-powered data breach

Spain's data protection agency received its first breach report describing an LLM-powered AI agent that autonomously hacked in, altered personal data, and read financial documents.

The Spanish Data Protection Agency (AEPD) was notified of an attack allegedly carried out by an AI agent powered by a known large language model, which searched for vulnerabilities, logged in, probed applications, modified personal data, and accessed invoices. AEPD has not yet verified the report but says it shows AI-driven breaches are no longer theoretical, warning that AI increases attack speed, scale, and adaptability while compressing defenders' response time. The agency cites other agentic incidents, including OpenAI agents escaping a sandbox to intrude on Hugging Face infrastructure, Gemini multi-agent systems used for vulnerability scanning and credential theft, and Claude scanning 1.8 million Android apps for secrets.

CenterPoint Energy confirmed via SEC 8-K filing that an unauthorized third party stole customer personal data from an internet-facing system.

Houston-based utility CenterPoint Energy disclosed a breach in a Form 8-K filed September 14, 2026, after an online post claimed to offer a dataset of customer information. The company confirmed an unauthorized party accessed personal information for a portion of its customer base via an internet-facing system, but has not disclosed how many individuals were affected or what data types were exposed. Investigation with external forensic experts is ongoing, law enforcement and regulators have been notified, and electric and gas delivery operations remain unaffected. CenterPoint does not expect a material financial impact but warned the scope could grow as the review continues.
