Description
Ledger's security research team (the Ledger Donjon) recently published a report showing that they were able to perform a laser fault injection attack against a Tangem card.
The headlines sound scary, but what does this actually mean for real Tangem users?
In this video, I break down:
✅ What Ledger actually discovered
✅ Why this is NOT a remote hack
✅ Why no crypto has been stolen from this exploit
✅ The equipment and expertise required to perform the attack
✅ Tangem's response to the report
✅ Why firmware updates matter for security
✅ What you should do if you've lost one of your Tangem cards
The most important takeaway is that this attack requires physical possession of a card, specialized laboratory equipment, and a highly skilled attacker. For most users, phishing scams, fake support messages, malicious software, and seed phrase theft remain far greater threats.
However, if you've lost one of your Tangem cards, this new information changes the risk calculation, and I explain exactly what action I recommend.
