A newly disclosed malware attack on several banks around the world may have netted as-yet unknown hackers at least $300 million, perhaps substantially more, according to a forthcoming report by the security firm Kasperky Labs and shared with The New York Times. The attackers, said to include Russians, Chinese and European hackers, managed to install remote access tool software (RATs) on computers used by several banks that have not yet been named — most were in Russia — to capture account information they used to impersonate bank employees. They then moved money to accounts they controlled. They also caused some ATMs to dispense cash seemingly at random, which cost one bank $7.3 million. Interpol, the global law enforcement agency, is investigating.
