Cyber bank robbers steal $1bn, says Kaspersky report.

Up to 100 banks and financial institutions worldwide have been attacked in an "unprecedented cyber robbery", claims a new report.

Computer security firm Kaspersky Lab estimates $1bn (£648m) has been stolen in the attacks, which it says started in 2013 and are still ongoing.
A cybercriminal gang with members from Russia, Ukraine and China is responsible, it said.
Kaspersky said it worked with Interpol and Europol on the investigation.
It said the attacks had taken place in 30 countries including financial firms in Russia, US, Germany, China, Ukraine and Canada.
"These attacks again underline the fact that criminals will exploit any vulnerability in any system," said Sanjay Virmani, director of Interpol's digital crime centre.
Kaspersky said the gang's methods marked a new stage in cyber robbery where "malicious users steal money directly from banks and avoid targeting end users".
The gang, which Kaspersky dubbed Carbanak, used computer viruses to infect company networks with malware including video surveillance, enabling it to see and record everything that happened on staff's screens.
In some cases it was then able to transfer money from the banks' accounts to their own, or even able to tell cash machines to dispense cash at a pre-determined time of day.
Kaspersky said on average each bank robbery took between two and four months, with up to $10m stolen each time.
