IF YOU USE A LEDGER HARDWARE WALLET, DO NOT IGNORE THIS SECURITY WARNING 🚨👀🔐
The biggest rule in hardware wallets is simple: what you see on your physical screen is what you sign 🛡️📱
If your device shows you are sending $10, you expect to sign only that $10 payment. But security researchers just proved a dangerous bug that breaks that exact promise ⚠️💸
What The Researchers Proved 🔬💥
Security team OneKey successfully reproduced an attack against the Ledger Ethereum app version 1.22.1 in their lab. An attacker can overwrite a transaction in device memory while you are still reading a genuine one on your screen 🖥️🔄
How The Attack Works In Simple Steps 🔍⚙️
The issue is a race condition (a timing bug between the screen display and the memory buffer): ⏱️🧠
1️⃣ You start a normal transaction (Transaction A) on your computer 💻
2️⃣ Your Ledger screen displays Transaction A for you to check 📱👀
3️⃣ While you review the screen, a script sends Transaction B into memory ⚡🕵️
4️⃣ The memory gets overwritten with Transaction B, but your screen still shows Transaction A 🔄🛑
5️⃣ You press the physical buttons to approve, and your device signs Transaction B ✍️😱
Current Status And The Fix 🛠️✅
Ledger confirmed the issue was resolved in Ethereum app versions 1.22.2 and 1.22.3. No user funds were stolen in the wild, but older versions remain vulnerable 🛡️🏢
If you use a Ledger device, open Ledger Live and update your Ethereum app to version 1.22.3 or newer immediately 🔄🔒
