A Morse-Code Message Became a Six-Figure Payment

Now, why is this concerning? Because the case highlights a six-figure exploit involving just two AI agents. One AI produced text. Another treated it as permission to spend.

If we look at the scale of AI agentic payments today, such scenarios could be a nightmare for the future of Agentic Finance.

Keyrock counted 176 million on-chain agent payments worth $73 million through April 2026. The median payment sat between $0.01 and $0.10, while 76% fell below $0.30. Small payments become a large control problem when software can make them continuously.
