The crypto space has long been plagued by hacking incidents and exploits, and now artificial intelligence is exacerbating the issue. Charles Guillemet, Ledger's chief technology officer, believes that AI tools are making it easier and less expensive to launch attacks on systems, thereby disrupting the economics of cybersecurity. In an interview with CoinDesk, Guillemet stated, 'Identifying vulnerabilities and exploiting them has become extremely easy.

The cost is essentially zero.' His comments come amidst a string of high-profile crypto heists, including the recent $285 million exploit of Solana-based Drift and the $25 million attack on yield protocol Resolv. Over the past year, crypto attacks have resulted in the theft or loss of over $1.4 billion in assets, according to DefiLlama data. The traditional security model relies on the principle that hacking a system should be more difficult and costly than the potential reward. However, AI is eroding this advantage by enabling tasks like reverse engineering software and chaining exploits to be completed in seconds.

For crypto, where code often controls large funds, this shift raises the stakes. Guillemet warned developers of blockchain protocols, 'You need to be perfect.' The problem is further complicated by AI-generated code, which can spread vulnerabilities more quickly. Guillemet emphasized that there is no straightforward solution to security, stating, 'There is no 'make it secure' button.

We will produce a lot of code that is insecure by design.' To address this issue, crypto protocols must rethink their security approach from the ground up. Guillemet recommends formal verification, which uses mathematical proofs to validate code, as a more robust approach than traditional audits. He also suggests hardware-based security, such as devices that isolate private keys from internet-connected systems, reducing exposure. For average crypto users, Guillemet's message is clear: assume that systems can and will fail.

He advises users to adopt a more cautious approach, such as using cold storage, strengthening operational security, and keeping sensitive data offline. Despite these precautions, risks still exist, including physical attacks targeting crypto holders. Guillemet anticipates a divide in the future, with critical systems like wallets and protocols investing heavily in security and adapting, while much of the broader software ecosystem may struggle to keep up.

He concluded, 'It's really easier to hack everything.'
