Ledger's Chief Technology Officer Charles Guillemet has issued a stark warning that artificial intelligence is fundamentally changing the threat landscape for cryptocurrency security. According to his statements on April 5, 2026, AI tools are driving down the cost and difficulty of cyberattacks on crypto platforms, creating a crisis that demands a complete rethink of digital asset security systems.
The warning comes as crypto hacks and exploits caused $1.4 billion in losses over the past year, with AI likely to make the situation worse. Guillemet explains that AI-generated code and increasingly sophisticated malware are forcing the industry toward formal verification, hardware-based security, and offline storage solutions.
The CTO emphasized that the economics of cybersecurity are breaking down as AI tools enable faster and cheaper attack methods. Users should assume that many current systems will eventually fail under this new AI-powered threat model, requiring immediate adaptation of security practices across the cryptocurrency ecosystem.
