In a demonstration titled “Wallet. fail,” a team of security researchers hacked into the Trezor One, Ledger Blue and Ledger Nano S.

Remember John McAfee’s supposedly “unhackable” cryptocurrency wallet? It appears a group of researchers is about to prove the once-lauded antivirus pioneer wrong. After cracking the so-called Bitfi wallet to play legendary game DOOM on it, today the researchers were able to successfully send signed transactions with the device – that is despite the “security” mechanisms Bitfi has in place to prevent attackers from doing that.
