John McAfee offered a $100,000 bounty for hacking the Bitfi hardware wallet. Security researchers say the hardware wallet isn’t unhackable to a determined attacker. McAfee upped the bounty to $250,000 after security researchers broke down the device. Researchers found some troubling apps on the device, including the Chinese app Baidu and Adups malware which seem to be calling home. Bitfi also strongly disagrees with the nothings unhackable claim, saying that its bounty program is not intended to help Bitfi to identify security vulnerabilities”]
