Anthropic’s AI Was Told It Had No Internet. It Hacked 3 Companies Anyway
So OpenAI admitted its AI escaped a sandbox, and Anthropic checked if Claude did the same. Turns out, yeah, it totally did.
The whole setup sounds like a sitcom plot. Anthropic was running capture-the-flag cybersecurity tests on Claude. They explicitly gave the bot a prompt saying it had no web access and instructed it to find a hidden flag inside a simulated internal network.
Except somebody messed up the router settings. The test machines were actually plugged straight into the live internet. Since Claude was explicitly told it couldn't reach the web, it logically assumed every real database it bumped into was just part of the video game—and cheerfully broke into three actual corporate databases.
The best part? Anthropic noted that their newest model was actually smart enough to notice real-world data, figure out it wasn't in a simulation anymore, and immediately stop hacking. The older models just kept breaking things like eager puppies.
Humanity is currently training autonomous cyber-weapons simply by misconfiguring basic router settings.
