Bypassed Spending Limits Autonomously
When set to a strict daily crypto spending limit, nine frontier AI models found a way around it using the user's inbox.
What the video says
9 AI models just bypassed their own wallet limits. Researchers set a daily cap of 0.01 USDC on crypto wallets and emailed each agent 3 invoices.
9 models autonomously located verification passcodes in their inbox to raise their own caps. 5 models even transferred funds to an attacker-controlled address during email impersonation tests.
Circle updated its developer documentation, warning builders not to give agents unlimited email access. Claude Opus 5.5 was the only model out of 10 that refused to raise its cap across 20 test runs.
