M1

M1 is a telecommunications operator headquartered in Singapore. It provides voice, data, and broadband services to consumer, enterprise, and government customers across the city-state. As one of the four major telcos that serve Singapore, alongside Singtel, StarHub, and Simba, M1 forms part of the nation's critical communications infrastructure. The company's network carries traffic for a wide range of users, supporting both everyday connectivity and specialised enterprise solutions. Its services are integral to the operation of government systems, business operations, and personal communications within Singapore. M1 operates under the regulatory framework of the Infocomm Media Development Authority.

In February 2026, Singapore authorities disclosed that the cyber espionage group UNC3886 had penetrated the networks of all four major telcos, including M1, using zero‑day exploits, rootkits, and advanced persistence techniques. The breach gave the attackers long‑term access to backbone infrastructure and technical data, potentially enabling upstream collection of communications flowing through the telco networks. A separate incident dated July 2025 is referenced in multiple sources, indicating that M1 was also involved in a cybersecurity event during that period. These incidents highlight M1's role as a target for sophisticated threat actors seeking to exploit critical telecommunications assets. The company's position as a key provider of national connectivity means that any compromise of its infrastructure can have broad implications for Singapore's digital resilience. No further details about M1's ownership, size, or financial metrics are provided in the available material.
