What did Ledger CTO Charles Guillemet say about AI and crypto security?

Ledger CTO Charles Guillemet warned that artificial intelligence is making crypto hacks faster, cheaper, and easier to execute. He said AI is lowering the cost of finding and exploiting vulnerabilities, breaking the traditional assumption that attacks are expensive and difficult.

Why is AI making crypto hacks more dangerous?

AI can automate complex tasks like analysing code, finding bugs, and chaining exploits in seconds. This reduces the skill and time required to attack crypto systems, increasing the number and frequency of potential exploits.

How much has been lost to crypto hacks recently?

More than $1.4 billion in crypto assets has been lost to hacks and exploits over the past year. Recent incidents include a $285 million exploit on Solana-based protocol Drift and a $25 million attack on Resolv.

What does this mean for crypto investors and traders?

It means the risk of losing funds due to hacks is increasing, even if the market itself is performing well. Security is becoming a key part of the investment thesis, not just price or adoption.

How does AI-generated code increase security risks?

AI-generated code can scale development but may introduce hidden vulnerabilities if not properly audited. Guillemet warned that insecure code could spread quickly as more developers rely on AI tools.

What is formal verification and why is it important now?

Formal verification uses mathematical proofs to ensure code behaves exactly as intended. It is considered more reliable than traditional audits, which can miss bugs, especially as AI increases code complexity.

Why are hardware wallets becoming more important?

Hardware wallets store private keys offline, reducing exposure to internet-based attacks. Guillemet highlighted them as a more secure option because they isolate sensitive data from compromised devices.

What new types of attacks are emerging with AI?

More advanced malware can scan infected devices for wallet seed phrases and drain funds without user interaction. This increases the risk even for users who follow basic security practices.

AI-driven hacks raise crypto security risks sharply

Artificial intelligence is making cyberattacks on crypto platforms cheaper and easier, according to Ledger chief technology officer Charles Guillemet, raising fresh concerns about digital asset security.

Guillemet said AI tools are eroding the traditional cost barrier to hacking, allowing attackers to find and exploit vulnerabilities far more quickly than before.

“Finding vulnerabilities and exploiting them becomes really, really easy… The cost is going down to zero,”

Said Ledger CTO, Charles Guillemet.

The warning comes as crypto exploits continue to mount, with more than $1.4 billion in losses recorded over the past year, including a recent $285 million attack on Solana-based protocol Drift.

AI is accelerating both attack and development cycles, with Guillemet warning that AI-generated code could introduce widespread vulnerabilities as insecure software is produced at scale.

To counter the threat, he pointed to formal verification and hardware-based security, such as offline wallets, as more robust approaches than traditional audits.

Guillemet said users should assume systems will fail and adopt stronger security practices, as increasingly sophisticated malware can target devices directly and extract sensitive data like wallet seed phrases.
