Tangem Wallet Laser Attack Explained: Competitor Ledger Found Vulnerability (What You Need to Know)

⚠️ FULL DISCLOSURE: Tangem is a sponsor of this channel and I promote their products. I made this video the same way I would if they were not a sponsor. Ledger — a direct competitor — published research showing they broke into a Tangem card with a laser. Here's exactly what they found, exactly how Tangem responded, and where I think both companies are spinning it. Read the primary sources yourself. Don't take my word for it: 🔬 Ledger Donjon research: https://donjon.ledger.com/blog/bypassing-tangem-card-security-with-laser-attack/ 🛡️ Tangem's official response: https://tangem.com/en/blog/post/lfi-response/ THE SHORT VERSION: Ledger found a flaw that cannot be patched and affects every Tangem card in circulation. Disabling password recovery does NOT protect you. It also requires physically stealing your card, roughly $250,000 in lab equipment, hardware-security experts, and it destroys the card in the process. There have been zero documented real-world losses from this class of attack on any hardware wallet, ever. Both of those things are true at the same time. Serious — and not a reason to panic. ⏱️ CHAPTERS 00:00 - Ledger Laser Attacked Tangem 00:32 - How the Laser Attack Actually Works 01:30 - The Uncomfortable Facts 02:15 - The Reassuring Facts 03:00 - How Tangem Responded 04:09 - Where BOTH Companies are Spinning It 04:45 - Where Tangem Was Soft on Facts 05:40 - What This Actually Means for You 07:20 - What I'm Watching Next 07:47 - The Bottom Line 🔑 IF YOU TAKE ONE THING AWAY: This changes the risk of a LOST OR STOLEN card. If your card goes missing and you hold meaningful funds — move them to new keys. Don't assume the password is enough anymore. If your card is still in your pocket, your day-to-day risk barely moved. The things actually draining wallets right now are phishing, fake apps, and malicious contracts — not lasers. 📌 On the sponsorship: Tangem is a sponsor of this channel. That's a real conflict of interest, not a throwaway line. My rule is simple — when something bad comes out about a sponsor, I cover it the same way I would if they weren't a sponsor. If I ever can't do that, I'll drop the sponsorship, not the story. Hold me to it in the comments. ⚖️ Nothing in this video is financial or security advice.
