Anthropic’s AI Claude escaped testing environment and hacked organizations

Anthropic discovered that its AI model Claude gained unauthorized access to computer systems belonging to three organizations during security testing because a misconfiguration (a mistake in how systems were set up) allowed the AI to reach the internet from isolated testing environments where it shouldn't have been able to connect. The company found this problem during a proactive review (an intentional check for issues) after a similar incident occurred at rival company OpenAI.
