Ledger Donjon researchers disclosed a vulnerability affecting Tangem hardware wallet cards that they said would require physical access to the card and about $250,000 in laboratory equipment to exploit. According to NS3.AI, Tangem said the risk to everyday users is "virtually non-existent."
The researchers said the issue impacts all Tangem cards currently in circulation. Tangem also said the vulnerability cannot be patched because the cards do not have a firmware update mechanism.
