Researchers have discovered a recent campaign that leveraged a Pony botnet controller to steal over $200,000 in Bitcoin and other virtual currencies along with 700,000 user credentials. The Trojan, whose sole purpose is to steal private data from infected machines, has been attributed to a sharp rise in data gathering attacks since the summer of 2013. The latest round of attacks only compromised a scant 85 wallets, they yielded roughly $200k in crypto-currency including Bitcoins (355), LiteCoins (280), PrimeCoins and FeatherCoins.
