Ledger Discloses Tangem Card Vulnerability; Tangem Downplays Security Risk

Key Facts

Amid intensifying competition over security standards in the hardware wallet market, Ledger researchers have disclosed a vulnerability in Tangem cards that allows for password resets. According to reports, the Donjon security team successfully demonstrated a laser-induced fault injection attack that bypasses firmware recovery-state checks. This flaw potentially enables unauthorized access if an attacker gains physical possession of the card, raising questions about the robustness of physical verification systems.

This disclosure comes as industry peers like Trezor and Jade continuously update their encryption protocols to mitigate physical attack vectors. Per market data, the rivalry between Ledger and Tangem involves contrasting design philosophies; Tangem utilizes screenless NFC cards, while Ledger insists on integrated screens for transaction verification. Tangem responded to the findings by stating that the risk to typical users is virtually non-existent, as the attack requires high-end laboratory equipment and specialized technical expertise.
