Electrum Wallet Attack Hid Bitcoin Theft Behind a Fee Increase
A malicious bitcoin wallet server exploited a high-severity vulnerability in Electrum, a lightweight Bitcoin wallet. Attackers intercepted legitimate payments, substituted fraudulent transactions, and tricked users into increasing transaction fees, leading to the theft of funds. Electrum released version 4.8.3 to close the loophole, warning users to upgrade immediately after developers discovered the flaw in earlier versions.
