SINGAPORE - A former United Overseas Bank (UOB) compliance officer was convicted on four charges under the Computer Misuse and Cybersecurity Act on Wednesday.
Koh Chee Tong, 30, pleaded guilty to conducting unauthorised searches on the bank's computer system in 2013, in order to pass the contact numbers of customers to an unlicensed moneylender.
Another 20 counts will be taken into consideration during sentencing, which will take place at a later date.
A district court heard that Koh had incurred a $16,000 gambling debt and turned to loansharks when he had difficulties repaying the loan.
He tried to negotiate repayment terms with a loanshark known only as "Ah King" who told him he would extend the latter's repayment period as well as reduce the interest payable for defaulting on his repayments if Koh provided him the names, NRIC numbers and mobile phone numbers of potential debtors.
Ah King wanted to use the information to expand his customer base.
On Oct 30, 2013, Koh used his staff identification number and password to access UOB's secure computer system, known as AS400. He wrote down the names of several account holders.Two days later he committed the offences again.
Some of the UOB customers later got harassing telephone calls and text messages from unfamiliar numbers, and at least two police reports were made.
Deputy Public Prosecutor Sanjiv Vaswani asked for a deterrent jail sentence of six months, citing public interest in preventing crimes that compromise the integrity of the banking and financial sector.
Said DPP Vaswani: "His actions in gaining unauthorised access into the secure system go against the very nature of his work, amounting to a clear abuse of his position, and the degree of trust reposed in him."
In mitigation, Koh's lawyer Kalidass Murugaiyan asked for a fine or a short jail term of not more than six weeks for his client, who is now a security guard with Certis Cisco.
The lawyer said that Ah King had harassed Koh repeatedly and threatened to vandalise his house, even though he had repaid his load.
Koh quit his job shortly after committing the offences.
District Judge Jasvender Kaur adjourned the case for sentencing on Jan 4.
