Former Bank Employee Leaked Customer Data, Aiding Billion-Dong Theft Scheme

Hanoi's People's Procuracy has indicted three individuals in a case involving the embezzlement of over 1 billion dong through forged checks and bank documents. The scheme targeted corporate accounts at Asia Commercial Bank (ACB). Trần Khánh Huyền, a former employee at ACB's Quán Toan branch in Hai Phong, is accused of intentionally leaking confidential work information. She allegedly provided Nguyễn Đình Chế, whom she met via Zalo, with sensitive customer data, including account balances and company seals.

Chế, 24, from Bac Ninh province, faces charges of fraud and forgery. According to the indictment, Chế devised the plan in late 2023 to fund personal expenses and pay off debts. He allegedly obtained company seal templates and signature stamps from ACB's internal system through Huyền. Using this information, Chế forged four requests for check issuance and four checks to withdraw funds from accounts of four different companies at ACB branches in Hoang Dao Thuy and Thanh Xuan.

Further complicating the scheme, Chế also forged two company seals and two signature stamps for two other firms. He then created two fake introduction letters and two fake payment orders to transfer funds. To execute this part of the plan, Chế hired Lê Công Tuấn, 38, from Hanoi, to impersonate company employees and fill out the forged documents under his direction. Tuấn is charged with forging four documents as an accomplice.

Investigators determined that Chế forged a total of 12 documents targeting six companies with accounts at ACB. The embezzled funds were used for Chế's personal needs. Huyền's alleged actions of providing customer data and seal information to an outsider are considered a breach of bank confidentiality, which prosecutors say enabled Chế's fraudulent activities.
