Man drove around Singapore with 'SMS blaster' that sent more than 10,000 phishing messages, gets jail
When he visited his sister while the device was in his car, he warned her about phishing messages targeting WhatsApp users.
In October and November 2025, a Malaysian man named Ong Kak Seng, 28, was sentenced to a year and nine months in jail and fined $1,500 for driving around Singapore with a "blaster device" that transmitted over 10,500 phishing messages. The device was capable of reaching more than 31,000 mobile phones within its coverage area, causing one person to lose over $1,800 after transferring cash to a third party's bank account.
Ong pleaded guilty to a cheating charge and must pay the fine or face an additional week in jail. He owed around RM80,000 to unlicensed moneylenders in Malaysia and was offered a job by a man known as "Bai Ge" to earn RM1,000 a day. Ong was instructed to drive around densely populated areas in Singapore for up to 12 hours daily while carrying the blaster device in his car.
