Artificial intelligence reduces costs and simplifies cyberattacks on crypto platforms, believes Charles Guillemet, CTO of hardware wallet manufacturer Ledger. He advised assuming that many systems will ultimately be vulnerable. For a long time, security was based on a balance, the Ledger executive explained: hacking a system should be more difficult and expensive than the potential benefit gained from hacking it. With the advent of AI, tasks that previously required months of work by qualified specialists can now be completed in seconds—just by formulating the right prompt to a chat bot. However, Guillemet believes that code created with AI carries many risks: the more developers rely on AI assistants, the faster vulnerabilities can spread. For the crypto sphere, where code manages large sums of money, this is dangerous, warns the expert. He believes that today, blockchain code must be flawless, as neural networks can hack it in seconds. In the face of new threats, crypto protocols need to rethink their security approaches. Guillemet called on developers to implement formal verification—using mathematical proofs to validate code. This method is more reliable than traditional audits, which may fail to detect certain errors, according to the crypto expert. He also recommended using hardware crypto wallets more frequently.
