How the Attack took places.?

Pulling off an attack of this scale must have took time, and Kaspersky says the hackers were patient in its execution. In order to steal as much as $10 million from some victims, the criminals reportedly had to infect bank computers and remotely install surveillance software to observe everyday behavior. Then, by mimicking employee actions, the hackers could make large transactions look like business as usual. To cash out, the money would be siphoned off into dummy accounts made in advance. One Kaspersky client reportedly lost $7.3 million from ATM transactions.

According to details, the such kind of sophisticated attack is ongoing and mostly has affected the banks of Russia but it is spread on to approximately 100 banks all over the banks.

While no banks have come forward to acknowledge the theft, experts are calling the attack potentially one of the largest bank heists ever.
