Ledger researchers disclose Tangem card flaw; Tangem says risk to everyday users is ‘virtually non-existent’

Ledger researchers have revealed a serious security flaw in Tangem cards, which can be exploited via a laser attack to reset passwords by circumventing a recovery-state check in the firmware. While Tangem asserts that the risk to regular users is minimal, this disclosure highlights ongoing security challenges in the cryptocurrency hardware wallet sector. As the crypto world increasingly relies on such devices for safeguarding assets, understanding these vulnerabilities and their potential impacts becomes crucial for both developers and users. This incident underscores the importance of rigorous security testing and the need for continuous improvement in the design of secure hardware wallets.
