Spain’s data protection authority, the AEPD, has published details of a personal-data breach allegedly carried out through an AI agent. The reported sequence included a successful login, vulnerability discovery, modification of personal data, and access to invoices. The authority describes the significant point as the agent’s ability to chain attack stages while receiving a goal, planning intermediate tasks, using tools, executing code, interpreting results, and changing its actions autonomously.
The investigation is still ongoing, and the available account does not establish how the system operated or whether safeguards were bypassed. The incident nevertheless broadens cyber-risk assessments: organizations must protect identities and credentials, shorten detection and response times, and prepare containment mechanisms that can operate at machine speed. The AEPD stresses that human oversight remains essential but must be supported by rapid defensive automation.
