South Korean regulators launched an inquiry on Monday into the country's biggest banking network, after a system glitch suspected to be caused by a cyberattack left customers without access to services for several days.
The AFP news agency reported that the country's Financial Supervisory Service and central bank officials visited the Seoul headquarters of the National Agricultural Cooperative Federation (Nonghyup) to investigate whether it had complied with computer security rules.
The trouble at Nonghyup began on Tuesday, when the bank suffered a system crash that left customers unable to withdraw and transfer money, use their credit cards and take out loans. The bank's services were partially restored after three days, but some services remained unavailable as of Monday, said AFP.
