Bitcoin Wallet Flaw Let Rogue Servers Swap Transactions and Steal Funds

A flaw in a Bitcoin wallet allowed malicious servers to steal funds when users attempted to speed up payments, according to CoinDesk.

Attackers substituted fraudulent transactions for genuine ones, then waited for users to authorize a fee increase. That approval enabled the theft.

At least one user lost bitcoin before developers released a fix. The report did not specify the amount stolen.
