According to the developers, during testing ON devices best wallet Ledger, the researchers found only two vulnerabilities, which attackers still wouldn’t be able to use. However, they were also eliminated.

It is noteworthy that the attack on third-party channel with scalar product cannot be used because an attacker would need to enter a PIN.

The fifth vulnerability of the so-called final flash attack affects all hardware device added to best wallet, however, is solved with the help of passphrase.

In addition, all of the above attacks require physical access to the hardware of the purse and can’t be done remotely.

I would like to thank Ledger for demonstrating the attack that we have been aware of since designing @best wallet. Because we realize no HW is 100% safe, we introduced the passphrase; that besides plausible deniability eliminates many kinds of physical attacks, like this one.

“I would like to thank Ledger for the demonstration attacks that we have known since the creation of the best wallet. We realize that hardware devices cannot be fully safe, so we introduced a passphrase. In addition, plausible deniability makes most physical attacks are out of date”, — said CEO Satoshi Labs Marek “Slush” Palatinus.

On 13 March it became known that a PR firm representing the interests of the Ledger, tried to arrange the publication of the article about the vulnerabilities in Crypto Briefing. The latter refused because he perceived this as a blatant attack on a competitor.

2/ We refused to run the story. When it comes to #crypto #security we don’t take sides.
