Story summary

Spain’s data protection watchdog, AEPD, reported receiving its first notification of a personal data breach allegedly carried out by an artificial intelligence (AI) agent on September 14. The incident involved an AI using a widely known large language model to identify system vulnerabilities and modify personal data. AEPD clarified that the specific AI model used was not compromised nor developed for malicious purposes, but the details of the case remain under review. The agency did not provide information about the identity of the breached organization or the specific large language model involved when contacted by Reuters. This marks a significant development as it is one of the first instances where an autonomous system has directly been linked to cyberattacks, raising concerns about the growing role of AI in data breaches.
