StarHub

StarHub is a telecommunications operator headquartered in Singapore. The company provides a range of services that include mobile voice and data, broadband internet, and pay‑television offerings. It serves both residential and business customers across the island nation. As one of the country’s major telecom providers, StarHub competes in a market that also includes Singtel, M1 and Simba.

StarHub’s network infrastructure supports nationwide coverage for 4G and 5G mobile services, as well as fibre‑based broadband connections. The company has been involved in several high‑profile cyber‑security incidents that highlight its role in critical national infrastructure. In February 2026, StarHub was among the four telcos compromised by the espionage group UNC3886, which used zero‑day exploits to gain persistent access to backbone systems. Earlier, in October 2016, the operator mitigated distributed denial‑of‑service attacks on its domain name servers that caused temporary broadband disruptions for home users.

These incidents underscore StarHub’s position as a key component of Singapore’s communications ecosystem, subject to oversight by the Infocomm Media Development Authority. The company’s experience in defending against sophisticated threats has contributed to sector‑wide advisories on strengthening telco defenses. StarHub continues to focus on delivering reliable connectivity and maintaining the resilience of its network services.
