How's this for a bank heist?

Kaspersky Labs reports that hackers from Russia, China, and Europe have stolen at least $300 million from more than 100 banks across 30 countries through fraudulent transfers, malfunctioning ATMs, and other methods.

Banks in Russia were targeted the most often, but the hackers are said to have also stolen from banks in the United States, Japan, and Europe.

The funds were stolen after hackers installed surveillance software on the banks' systems. Then they fussed about with the financials to steal about $10 million from the bank, using everything they learned to avoid raising suspicion.

It's almost as if the hackers were emulating Robin Hood: they didn't steal from individuals; they stole from the banks themselves. The only thing stopping them from being full "Hood" is the part where the money is given to the poor.

Unless you count the bank customers waiting near the ATMs that dispensed cash to anyone standing nearby when the hackers struck, that is, though I suspect that was motivated more by security concerns than by pure altruism.

Kaspersky Labs is unable to name the banks affected by this global heist. And several industry groups told the New York Times, which first reported on the Kaspersky report, only that their members are aware of growing cyber threats.

While the report confirms that $300 million was stolen through this heist, the Times says the actual number could approach $900 million, making this the largest caper in the history of robbing banks.
