Whereas Fireblocks says that assaults exploiting the vulnerabilities would have been “sensible,” the agency believes their complexity made them tough to find prematurely of Wednesday’s disclosure. “The possibilities that somebody – some malicious actor from, for instance, North Korea figured it out months earlier than we figured it out and disclosed it to pockets suppliers – I’d say that the chance of that could be very, very, very low,” Fireblocks CEO Michael Shaulov instructed CoinDesk.
