Singapore police arrested six men in coordinated raids on 9 September 2024, saying they were believed to be linked to a global syndicate involved in malicious cyber activity. A later arrest brought the number of men charged in the case to seven. In November 2025, three pleaded guilty and were sentenced; the latest official update located for this article said proceedings against two others were ongoing.
What happened in the September 2024 raids?
On 9 September 2024, about 160 officers from the Singapore Police Force’s Criminal Investigation Department, Police Intelligence Department and Special Operations Command, together with the Internal Security Department, conducted simultaneous raids at residential locations across Singapore. Six men were arrested: five Chinese nationals aged 32 to 42 and one 34-year-old Singaporean, according to the Singapore Police Force.
Police said they believed the men were linked to a global syndicate conducting malicious cyber activities. That was the police’s account at the time of the arrests, not a finding of guilt against all six.
What did police say they found?
Police reported finding several kinds of material at the residences. These were described as alleged evidence; possession of an item by itself does not establish that its owner committed an offence.
#1 Best Overall
- Credentials for internet servers used by known hacker groups.
- Data obtained without authorisation, including personal information relating to people outside Singapore.
- Hacking tools and software used to control malware, including PlugX.
- Electronic devices, cash and cryptocurrency.
The five Chinese nationals were expected to face offences under Singapore’s Computer Misuse Act 1993. Police accused the Singaporean of abetting unauthorised access.
Why do later reports refer to seven men?
The six-person figure refers specifically to those arrested in the 9 September raids. CNA later reported that a seventh Chinese national was arrested subsequently and charged, bringing the total number of men charged in the case to seven. He was not one of the six arrested during the coordinated raids.
| Date | Case stage | What was reported |
|---|---|---|
| 9 September 2024 | Raids and arrests | Six men arrested at residential locations across Singapore. |
| 10 September 2024 | Initial charges | The five Chinese nationals were expected to face Computer Misuse Act offences; the Singaporean was accused of abetting unauthorised access. |
| Subsequently | Additional arrest | CNA reported that a seventh Chinese man was arrested and charged. |
| 5 November 2025 | Guilty pleas, convictions and sentences | Three men pleaded guilty, were convicted and sentenced. |
What happened in court?
On 5 November 2025, the Singapore Police Force announced that Yan Peijian, Huang Qinzheng and Liu Yuqi had pleaded guilty, been convicted and sentenced. The District Court judgment records their guilty pleas and sentences.
| Defendant | Sentence |
|---|---|
| Yan Peijian | 28 months and one week of imprisonment |
| Huang Qinzheng | 28 months and one week of imprisonment |
| Liu Yuqi | 28 months and four weeks of imprisonment |
The Singapore Police Force said the convictions covered membership in a locally linked organised criminal group, acquiring property representing criminal benefits, retaining computer programmes with intent to facilitate Computer Misuse Act offences, and making false employment declarations.
Rank #3
In its 5 November 2025 update, police said proceedings for two other accused were ongoing and that the syndicate leader was outside Singapore and at large. That is the latest official status update cited here; it should not be read as confirmation of their status on a later date.

No. The sources cited here describe a global cybercrime syndicate but do not publicly identify it by name. They also do not establish a link to a particular state or named hacker collective, so attributing the group to one would go beyond the reported facts.
