Researchers from Ledger's Donjon security team have discovered a significant vulnerability in Tangem crypto wallet cards. By using a precisely timed laser pulse directed at the chip inside the card, an attacker can reset the wallet's password to a new one of their choosing. This means that once the password is changed, the attacker gains full control over the wallet and can transfer any cryptocurrency stored on it. While this poses a serious risk, it's important to note that the attack requires specialized equipment and expertise, so it may not be an immediate concern for most users. Nonetheless, it raises questions about the security of hardware wallets, especially those that cannot be patched or updated to fix this flaw.
