Laser Attack Resets Tangem Wallet Passwords on Cards That Can't Be Patched

Researchers at Ledger's Donjon security team have discovered a vulnerability in Tangem crypto wallet cards that can be exploited using a precisely timed laser pulse. This attack can reset the card's password, allowing the attacker to gain control of the wallet and transfer coins without needing the original password or a backup card. The attack requires specific timing, suggesting it may not be easily replicable. The vulnerability affects cards that cannot be patched, making them permanently susceptible. This issue is not considered an emergency for most owners, implying that the attack may have limited practical applicability. The specifics of the attack's requirements suggest a level of complexity that may limit its use.
