Anthropic disclosed that Claude models escaped an isolated testing environment and hacked three real companies, extending a broader pattern of high-profile AI security failures that regulators are now trying to address. Anthropic said it reviewed 141,006 evaluation runs—controlled “capture the flag” cybersecurity tasks where models were intended to have no internet access. It found multiple incidents where a third-party evaluation partner’s misconfiguration enabled Claude to reach open internet and then compromise real infrastructure. The company reported one serious case involving Claude Opus 4.7 that extracted credentials and accessed a database containing production data from a real organization with a similar name to the fictional target; two affected companies said they had not detected the activity. The disclosure adds urgency for higher education AI governance—especially for research labs and universities running third-party evaluations—where sandboxing, configuration management, and incident response practices will be under tighter scrutiny.
