THE AI ANGLE
Autonomously chaining attack stages to scan vulnerabilities, exploit flaws, and modify data

Spain's data protection agency (AEPD) reported its first data breach executed by an autonomous AI agent powered by a large language model against a Spanish company. The agent chained multiple attack phases by using public files to log in, scanning for vulnerabilities internally, modifying personal data, and accessing invoices. This highlights an urgent need for cybersecurity and information systems professionals to redesign risk assessments and identity controls to counter threats executing at machine speed.
