Officials of the Ministry of Public Security Wednesday said they have placed man in custody for four months to investigate the hacking of a bank's data and stealing nearly VND330 million (US$15,791).
Initial information is that last August, Nguyen Chi Toan, 27, staff of Trans Infotech Vietnam Company, was assigned to support the payment solution service provider's customer, Mekong Housing Bank (MHB), to repair problems at its card center in Ho Chi Minh City
During the repair work, Toan found out passwords to access the bank's data system, and he later changed some data information out of curiosity, investigators said.
In January this year he used the fake ID card of a person named Nguyen Nan to open an automated teller machine account at MHB.
He then accessed the bank's data again, choosing an account named Le Ngoc Truc that hadn't been active for a long time. He changed the account's number to the one of Nan's, and added VND250 million ($11,990) to the former.
Toan then used Nan's card to withdraw about VND100 million ($4,787) from different ATMs in the city, before adding another VND450 million ($21,545) to the account.
Investigators said Toan had withdrawn nearly VND330 million via Nan's account.
He also used the same trick with another account to place up to VND1.5 billion ($71,804) in it.
However, before he could withdraw money from it, Toan lost his ATM card, prompting the bank to lock it. It was then that the bank detected problems with Nan's account and asked for help from the ministry's investigators.
