A captain with the Singapore Armed Forces (SAF) bought multiple credit card details that belonged to others from someone he met on the Dark Web.
The Dark Web contains websites that are not indexed by search engines such as Google. It is accessible only by special software and users and website operators can remain anonymous as well as untraceable.
After that, Yang Jiafeng, who was from the SAF Intelligence Surveillance Reconnaissance Training Centre, went online and unlawfully used the information to buy 88 e-vouchers worth more than $10,000 in total.
The Straits Times understands that he has since been suspended from the SAF.
Yang, 32, was sentenced on Monday to 20 weeks' jail after he pleaded guilty to three counts of causing a computer to access without authority the data in another computer. These offences fall under the Computer Misuse and Cybersecurity Act.
Deputy Public Prosecutor Cheng Yuxi said the SAF regular officer got to know the netizen known only as "Mr Tree" through an online forum on the Dark Web.
Yang then bought from him multiple credit card details belonging to others, and some of them involved Maybank. He paid Mr Tree with bitcoins but court documents did not reveal the amount.
Yang later created three accounts on an online application called Fave, which is a mobile payment and deals platform.
The court heard that one of its main features, called "Fave deals", offers discounts in areas such as food and beverage, travel as well as beauty and wellness. Another feature is known as "FavePay", which is an accepted mode of payment for selected merchants.
Yang linked the credit card credentials he bought from Mr Tree to his three Fave accounts.
Between end-February and early April 2018, Yang used the Fave accounts to purchase e-vouchers through Fave deals.
He then refunded these vouchers to obtain online credits from Fave.
After that, he used the credits to buy items from merchants that supported the FavePay function.
His offences came to light when a fraud analyst from Maybank Singapore alerted the police on May 8, 2018.
He later made full restitution, the court heard.
Yang is now out on bail of $10,000, and will surrender himself at the State Courts on Monday to begin serving his sentence.
