Bitcoin OG Says He Is Watching for Next Major Exploit as AI Models Get Stronger

Longtime Bitcoin figure CobraBitcoin has sounded the alarm over a new security challenge facing the cryptocurrency industry as frontier artificial intelligence models become dramatically better at coding, vulnerability discovery and autonomous cyber operations.

The pseudonymous Bitcoin veteran says he is watching for the next major exploit after the arrival of increasingly capable models from OpenAI and Anthropic. 

He has pointed to the fact that much of Bitcoin’s critical infrastructure is open-source and can therefore be analyzed at machine speed.

His warning comes shortly after OpenAI released GPT-6 Astra and Anthropic rolled out Claude Fable 5.1, two models designed to perform substantially longer and more complicated software-engineering tasks than their predecessors.

Increasingly autonomous systems could scour Bitcoin Core, Lightning implementations, wallets, libraries and other infrastructure for ordinary software bugs that human reviewers have missed. 

And there is now growing evidence that AI is becoming unusually effective at probing the latter.

Critical cyber threshold 

OpenAI says Astra is the first model it has broadly deployed to reach the “Critical” cybersecurity capability level under its Preparedness Framework.
