French crypto unicorn Ledger warns of AI security risks

Artificial intelligence is "changing the security landscape". That's according to Ledger, a French unicorn of cryptocurrency that's seeking a bigger role in digital security. Chief Technology Officer Charles Guillemet says: "Finding vulnerabilities and exploiting them costs almost nothing. So this is the new challenge that we have, as the security industry in general – how can we raise the bar for security so it becomes so difficult to break systems? And I think hardware is part of the equation."
