Bitcoin

Mt. Gox, the largest exchange for buying and selling bitcoins, is temporarily shutting down following an uptick in activity on the site sparked by a massive drop in the digital currency's price.

Of all the virtual currencies out there, BitCoin is the most interesting from a technical perspective -- and the least interesting from the business point of view. BitCoin is a peer-to-peer virtual currency that uses cryptography to control the creation and transfer of money.

A newly identified Mac OS X Trojan bundles a component that leverages the processing power of video cards (GPUs) to generate Bitcoins, a popular type of virtual currency.

An anonymous hacker used phony Bitcoins (BTC) last month to drive down the price of the online currency from $17.50 to a penny within the span of 30 minutes, Bitcoin exchange firm Mt.Gox has revealed. The hacker was able to create 2 million counterfeit BTC by manipulating the company's trading database after gaining access to a compromised administrator account on June 19, according to Adam Barr, head of support for Mt. Gox.
