An unnamed organization reportedly notified Spain's data protection authority that a third party used an AI agent powered by a known language model to carry out a multistep intrusion that resulted in unauthorized changes to personal data and access to invoices. The AEPD said the case remains under review and has not identified the organization, attacker, AI system, attack date, or number of affected people.

What this means for youAt home, an AI tool that gets hijacked could expose or change your personal records held by a company you use. At work, companies that connect AI agents to customer systems need tight limits on what those agents can touch. In government, regulators like Spain's data protection authority are now looking at how these breaches happen.
