A security duo demonstrated that it is possible to hack the John McAfees Bitfi cryptocurrency wallet. A new attack that could allow them to steal all the stored funds from an unmodified Bitfi wallet. The wallet relies on a user-generated secret phrase and a salt value to cryptographically scramble the secret phrase. The attack is trivial to carry out and doesnt require any specific hardware. McAfee offered a $250,000 bounty for anyone who could successfully carry out an attack that will result with the theft of the coins.”]
