Liong Yan Sin, a former DBS employee in Singapore, was on Monday (Nov. 21) sentenced to 16 weeks' jail for accessing and disclosing customer information without authorisation.

The 32-year-old Singaporean pleaded guilty to 16 charges in total, 10 of them under the Computer Misuse Act and the other six under the Banking Act.

Another 42 charges taken into consideration in his sentencing.

Accessed customer info even though he was not supposed to

According to CNA, Liong was a DBS collections officer between July 2016 and December 2018.

As part of his job scope, he was given access to DBS' Customer Information System.

The Straits Times reported that Liong was made aware when he first joined DBS that he was not supposed to disclose customer information for unauthorised purposes.

However, Liong still went ahead and searched for customers whose names he had seen in online forums.

He also checked his friends and relatives' details.

Charge sheets seen by Mothership showed that Liong did a number of such searches from May 2018 to December 2018.

He had committed the offences as he was "curious", CNA and ST reported.

Also helped his friends to access customer info

Liong had also accessed customer information without authorisation to help his friends, co-accused persons Dinath Silvamany Muthalliyar and Ang Kok How.

Dinath Silvamany Muthalliyar

Dinath had previously worked with Liong at DBS, before he moved to the Ministry of Manpower (MOM), according to CNA.

From June 2018, he began asking Liong to find out the salary details of his colleagues at MOM.

Liong agreed and gave Dinath the information he retrieved without authorisation from the DBS system on five occasions.

Dinath's case is still ongoing.

Ang Kok How

Liong and Ang knew each other through gambling, drinking, and playing basketball, reported ST.

The two men were also mutually acquainted with a woman named Kelly.

Kelly had owed Ang about S$23,000 in September 2018 and became uncontactable.

Ang subsequently asked Liong for help to contact Kelly.

Liong retrieved Kelly's details in the DBS system without authorisation and sent them to Ang via WhatsApp.

Ang's case is still before the courts.

Liong's offences were eventually discovered by DBS, and a police report was lodged in 2018.

Liong was allowed to defer his jail term.

He will begin his sentence in Dec. 19, 2022.
