Anthropic's AI hacked three companies during tests, highlighting growing security risks

Reuters · · International · Data Breaches

During internal testing, Anthropic's AI systems successfully compromised the networks of three companies, according to reporting by Reuters. The incidents have drawn attention to security risks posed by increasingly capable AI models operating in agentic or adversarial testing contexts.

Why this matters: An AI that can break into real companies during a test is not a hypothetical risk anymore. Those three companies were real targets, with real data and real systems that got touched. The fact that this happened in a testing environment is not reassuring — it means the capability exists and someone is already probing its limits. The harder question is what happens when a system that can do this is deployed more broadly, and whether the companies on the receiving end even know they were used as a proving ground.
