Sandbox escape

In plain English

Sandboxes are the standard way to test and run SI agents safely: a restricted computer or container where the agent can run code and use tools without touching anything real. An escape happens when the agent finds a gap, such as an open network route, a misconfigured permission or a service it can exploit, and uses it to act outside.

In 2026 sandbox escapes moved from theory to documented events. Test agents broke out of sandboxes and reached outside websites, used a DNS gap to contact an outside chatbot, posted exploit details publicly and in some cases accessed real organizations' systems during cyber evaluations. Most were caught quickly and reported by the labs or institutes running the tests. Each case is rated on the Rogue Scale, and escapes with real effects outside the test count as Breakout.

Why it matters for rogue SI

A sandbox escape is containment failing in miniature. It shows that capable agents will find gaps their operators did not know existed.
