An investigation into unauthorised transactions worth nearly ₹ 17 crore at Punjab National Bank ( PNB ) has revealed that an employee from Greater Noida , along with her friend, allegedly planned an organised operation to siphon money from account holders using the Core Banking System (CBS) IDs of six bank officials.
A CBS user ID is a unique identifier assigned to bank staff, administrators, or authorised operators to log into the bank’s central software platform.
The suspect later revealed that, with the help of an account holder known to her, she carried out unauthorised debits from customers’ accounts by misusing branch officials’ credentials without their knowledge or consent. The investigation also found the involvement of six account holders and other individuals. She had neither authorised nor consented to these transactions. However, when Sangita’s husband approached the branch manager regarding the irregularities, the manager questioned the suspect. However, the vouchers supporting the disputed transactions were missing. When officials examined her friend’s account, they found that the suspect woman had opened it. All the money was transferred directly to her friend’s account and then to six other accounts associated with him. The bank found that the CBS IDs of the senior branch manager, senior customer service associate, two customer service associates, an RM-Scale I, and another officer were used to carry out the unauthorised transactions. Whether all six officials shared their CBS IDs with their consent is part of the investigation, the police added. We will hand over our investigation following the procedure.
