Spain's data protection authority, the AEPD, has received a notification regarding an alleged cyberattack that reportedly leveraged an AI agent powered by a known large language model (LLM). This marks the first such reported incident in the country, according to BleepingComputer. The notification was made on September 16, 2026, but details remain scarce. The AEPD has not yet confirmed the attack or released official statements. The use of AI in cyberattacks is a growing concern, as attackers increasingly adopt generative AI to craft sophisticated phishing campaigns, automate malware, or exploit vulnerabilities. However, in this case, the exact role of the AI agent and the nature of the data theft are not yet clear. The incident underscores the evolving threat landscape where AI is both a defensive and offensive tool. Organizations are advised to monitor AI-related threats and ensure robust data protection measures are in place.
Security Details
