Over 100 banks hit by cyberattack: report

A sophisticated global cyberattack struck more than 100 banks in 30 countries stealing hundreds of millions of dollars, The New York Times reports.

Citing a soon to be released report from computer security company Kaspersky Lab, the newspaper said the attack involved malicious software that gave hackers long-term access to banking systems.

A group of Russians, Chinese and Europeans was able to siphon off around $US300 million ($A387 million) in one of the world's largest bank robberies, the report said.

The money was transferred to bank accounts around the world in small-value amounts to avoid detection.

Hackers largely focused on banks in Russia, but millions of dollars were also taken from banks in Japan, the Netherlands, Switzerland and the United States as well, the Times said.

Hackers had such advanced access to the banks' systems that they could force ATM machines to dispense cash at specific times and locations where hackers could pick it up.
