Cryptocurrency wallet startup Bitfi claims their wireless open-source hardware wallet for cryptocurrency cold storage is “unhackable.” Cyber security expert and cryptocurrency influencer John McAfee vehemently supports the device, so much so that he’s offered up a $100,000 bounty to anyone who can meet three bounty criteria.

According to a new report, researchers are claiming to have successfully breached the device’s security and have met the conditions required to claim the full bounty.

Last week, news broke about a 15-year-old who was able to gain root access to the device and run the iconic video game Doom on it. Despite the young hacker publicizing his progress, the actual criteria of hacking the device, extracting the coins, and proving the wallet is empty was not met. McAfee took to Twitter to defend the device.

“The wallet is hacked when someone gets the coins. No-one got any coins. Gaining root access in an attempt to get the coins is not a hack. It's a failed attempt. All these alleged "hacks" did not get the coins.”

This latest claim from security researcher Andrew Tierney has much more weight to it. The researcher tweeted a screenshot of a line of code, claiming it was "a transaction made with a MitMed Bitfi, with the phrase and seed being sent to a remote machine.”

Bitfi and McAfee were quick to challenge the Doom video when it surfaced, but have yet to address these recent claims. One thing is for sure: Bitfi is not as “unhackable” as Bitfi and McAfee thought.

Bitfi is a wireless cryptocurrency hardware wallet that supports Bitcoin, Monero, Litecoin, Ethereum, NEO and Ethereum-based ERC-20 tokens.
