A Malaysian man drove around Singapore for up to 12 hours a day with an "SMS blaster", transmitting more than 10,500 phishing messages to various mobile phone users in October and November 2025.
The device mimicked a mobile network and pushed phishing messages to phones within its range, tricking users into providing their WhatsApp login details through a fraudulent webpage, CNA reported.
More than 31,820 mobile phones came within the coverage area of the SMS blaster, and at least one victim reported losing more than $1,800 after transferring money to a third-party bank account.
Ong Kak Seng, 28, took on the job after accumulating debts of around RM80,000 (S$24,900) with unlicensed moneylenders, according to The Straits Times.
He was sentenced to a year and nine months' jail and fined $1,500 on Monday (Sept 14).
Ong pleaded guilty to one count of cheating. He will serve an additional week in jail if he fails to pay the fine.
Court documents cited by The Straits Times showed that Ong became acquainted with a man known as "Bai Ge" in 2023.
In October 2025, Bai Ge learned of Ong's debts and offered him a job that paid RM1,000 a day.
The job involved driving around densely populated areas in Singapore or Hong Kong for between 10 and 12 hours a day with an SMS blaster in his car, reported CNA.
The court heard that Ong knew the work was illegal, as the amount offered was about 10 times what a legitimate driver in Malaysia would typically earn.
Ong chose to work in Singapore and later learned how to assemble and operate the SMS blaster at Bai Ge's home in Malaysia.
On Oct 12, 2025, Ong assembled the device and placed it in his car, The Straits Times reported.
He also bought two mobile phones to operate the setup.
One phone reportedly functioned as his "primary device" which he paired with the blaster device to turn the device on and off remotely using an application.
The other phone operated as a "secondary device", in which he would grant the "primary device" Internet access through the "mobile hot spot" function, according to The Straits Times.
He reportedly drove around numerous locations in Singapore between Oct 12 and Nov 18, 2025, with the device, antennae and various battery packs at the back of his car.
He also met up with a Singaporean, Lie Dao Jing, who was allegedly performing the same task as him. Lie's case is pending, reported The Straits Times.
Ong was reportedly arrested on Nov 18, 2025 when officers from the Singapore Police Force's Police Intelligence Department and Commercial Affairs Department conducted an islandwide operation to catch those involved in transmitting phishing messages, based on multiple reports from the public.
The prosecution argued that the potential for harm in Ong's case was high, especially considering the syndicated and transnational nature of the crime, CNA reported.
The prosecutor also said Ong displayed a degree of sophistication in assembling and operating the SMS blaster, adding that scam-related offences remain a "major and fast-growing crime of concern in Singapore".
"When members of transnational crime syndicates are apprehended, the appropriate response is the unflinching imposition of appropriately stiff sentences in dealing with transgression," said the prosecution.
Ong's lawyer, Claire Chong, noted that the actual harm of his offence only involved one victim.
"Mr Ong plugged things into a machine and placed this in his car. He covered the SMS blaster device with a cardboard box. All of this was done in accordance with instructions and teaching from Bai Ge. This was not, by any means, sophisticated," said Chong.
For cheating, Ong could have been jailed up to 10 years and fined.

2025年10月和11月，一名马来西亚男子每天驾车在新加坡四处行驶长达12小时，使用“短信群发器”向各种手机用户发送了超过10500条钓鱼短信。
据中央社报道，该设备模仿移动网络，向其覆盖范围内的手机推送钓鱼信息，诱骗用户通过欺诈网页提供其 WhatsApp 登录信息。
超过 31,820 部手机进入了短信群发器的覆盖范围，至少有一名受害者报告称，在向第三方银行账户转账后损失了超过 1,800 美元。
据《海峡时报》报道，28 岁的翁国生 (Ong Kak Seng) 在欠下无牌放贷者约 8 万令吉（2.49 万新元）的债务后，接受了这份工作。
周一（9 月 14 日），他被判处一年零九个月监禁，并被罚款 1500 美元。
翁某承认一项欺诈罪名。如果他未能缴纳罚款，将被加判一周监禁。
《海峡时报》援引的法庭文件显示，翁某于 2023 年结识了一位名叫“白哥”的男子。
2025年10月，白哥得知翁负债累累，便给他提供了一份日薪1000令吉的工作。
据亚洲新闻台报道，这份工作需要每天驾驶汽车在新加坡或香港人口稠密的地区行驶 10 到 12 个小时，车上装有短信群发器。
法庭获悉，翁明知这份工作是非法的，因为所提供的报酬大约是马来西亚合法司机通常收入的 10 倍。
Ong 选择在新加坡工作，后来在马来西亚 Bai Ge 的家中学习了如何组装和操作短信群发器。
据《海峡时报》报道，2025年10月12日，翁组装了该装置并将其放在自己的车里。
他还购买了两部手机来操作这套设备。
据报道，其中一部手机是他的“主要设备”，他将其与发射器设备配对，通过应用程序远程打开和关闭该设备。
据《海峡时报》报道，另一部手机作为“辅助设备”，他可以通过“移动热点”功能为“主设备”提供互联网接入。
据报道，2025 年 10 月 12 日至 11 月 18 日期间，他驾车在新加坡多个地点转悠，车后备箱里装着该设备、天线和各种电池组。
他还与一名新加坡人李道京会面，据称李道京也在从事与他相同的活动。《海峡时报》报道称，李道京的案件仍在审理中。
据报道，2025 年 11 月 18 日，新加坡警察部队情报部门和商业事务部门的警员根据公众的多起举报，在全岛范围内展开行动，抓捕参与传播网络钓鱼信息的人员，随后逮捕了 Ong。
据亚洲新闻台报道，检方认为翁某案的潜在危害性很高，尤其考虑到该犯罪的集团性和跨国性质。
检察官还表示，翁某在组装和操作短信群发器方面表现出了相当的熟练程度，并补充说，诈骗相关犯罪仍然是“新加坡一个主要且快速增长的令人担忧的犯罪”。
检方表示：“当跨国犯罪集团成员被抓获时，正确的做法是对违法行为毫不动摇地处以适当的严厉刑罚。”
Ong的律师Claire Chong指出，他的犯罪行为实际造成的伤害只涉及一名受害者。
“翁先生把东西插到一台机器上，然后把机器放在车里。他用纸箱盖住了短信群发装置。所有这些都是按照白哥的指示和教诲进行的。这绝非什么高明的做法，”钟先生说。
如果犯了欺诈罪，翁某可能被判处最高 10 年监禁并处罚款。
