Kaspersky Lab researchers revealed that cyber-crooks stole tens of millions of dollars by hacking Eastern European banks through direct connections to local networks. At least eight banks, dubbed collectively as DarkVishnya, were targeted.
Cyber-criminals pulled off the heists by first entering banks under the guise of couriers, job seekers, or something similar and left behind hidden devices, such as Bash Bunny, Raspberry Pi, inexpensive laptops, or netbooks.
