SecureMac: SecureMac has discovered a new Trojan Horse called OSX/CoinThief.A, which targets Mac OS X and spies on web traffic to steal Bitcoins.
This malware has been found in the wild, and there are multiple user reports of stolen Bitcoins. The malware, which comes disguised as an app to send and receive payments on Bitcoin Stealth Addresses, instead covertly monitors all web browsing traffic in order to steal login credentials for Bitcoin wallets.
