On Wednesday, South Korean banks and broadcasting companies suffered from a cyberattack that many believe to be the work of a network of North Korean hackers.
The attack shut down ATM service for a number of banks, and many couldn’t use their debit or credit cards to make purchases. Employees at KBS, a major network, reported that files simply began disappearing from their computers.
North Korea has previously made threats of hacking attacks against the South. Last year they threatened to shutdown MBC and KBC, two national networks in Korea.
No personal information was leaked, and government networks were not affected.
