Singapore's four major telecom operators — Singtel, StarHub, M1, and Simba — are under threat from cyber espionage group UNC3886.The foreign actor targeted the telecommunications sector in 2025 but did not succeed in stealing any personal or sensitive customer data, said the Cyber Security Agency of Singapore (CSA) and the Infocomm Media Development Authority (IMDA) in a statement on Monday (Feb 9).«At stake was not just sensitive data,» said Josephine Teo, Minister for Digital Development and Information and Minister-in-charge of Cybersecurity and Smart Nation Group, at an engagement event to recognise cyber defenders on Monday.«The consequences could have been more severe. If the attack went far enough, it could have allowed the attacker to one day cut off telecoms or internet services.»UNC3886 was publicly identified as the advanced persistent threat (APT) group conducting a «serious» and ongoing attack on Singapore's critical infrastructures by Coordinating Minister for National Security K Shanmugam in July 2025.
