Specifically, the Ledger’s customer support agent famous:
From a technical standpoint, it is at all times been possible to plan firmware that aids in key extraction. Whether or not you had been conscious or not, you’ve got at all times relied on Ledger to not create such firmware.
This tweet set the Twitter sphere on hearth, with many customers accusing Ledger of misrepresenting the safety measures of its pockets. Some critics even introduced up an alleged Ledger submit from November, which said that “a firmware replace cannot extract personal keys from the Safe Component,” suggesting that Ledger had contradicted its personal statements.
