AI Just Made Hacking Nearly Free. The Entire Crypto Industry Is Panicking.

Ledger CTO says AI has driven the cost of finding and exploiting vulnerabilities to near zero. $1.4B stolen last year.

The economics of hacking just broke. And nobody in crypto is ready for what comes next.

Charles Guillemet, the CTO of hardware wallet maker Ledger, just dropped the most alarming quote in cybersecurity this year: "Finding vulnerabilities and exploiting them becomes really, really easy. The cost is going down to zero."

That is not hyperbole. It is a description of what AI tools are doing to the fundamental balance that kept systems secure for decades. The old model was simple: it should cost more to break a system than you could steal from it. AI just flipped that equation on its head.

The numbers back it up. Over $1.4 billion in crypto assets were stolen or lost to hacks in the past year alone. Just this week, Solana DeFi protocol Drift was drained of $285 million. A week before that, yield protocol Resolv lost $25 million. These are not fringe projects. These are platforms managing real money.

What changed? AI can now do in seconds what skilled security researchers used to spend months on. Reverse engineering software, finding exploit chains, crafting attack vectors. The barrier to entry for serious hacking just collapsed. You do not need a nation-state budget anymore. You need a laptop and the right prompts.

And here is the part that should terrify everyone building on blockchain: AI-generated code is making it worse from the other direction too. Developers using AI to write smart contracts are shipping vulnerabilities faster than ever. "There is no make it secure button," Guillemet said. "We are going to produce a lot of code that will be insecure by design."

So AI is simultaneously making it easier to attack systems AND easier to build vulnerable ones. That is not a security problem. That is a structural crisis.

Guillemet points to formal verification, using mathematical proofs to validate code, as one potential defense. Hardware wallets that keep keys offline are another. But his advice for regular crypto users is blunt: "You cannot trust most of the systems that you use."

This is the story nobody in Silicon Valley wants to talk about. The same AI tools being celebrated for productivity are creating the biggest cybersecurity crisis in history. The attackers have AI now. The defenders are still catching up. And $1.4 billion says the attackers are winning.
