Man who drove around S’pore with ‘blaster device’ to transmit over 10.5k phishing messages gets jail
Over 10,500 phishing messages were transmitted to mobile devices between October and November 2025.
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.
