StarHub home broadband network was disrupted by legitimate traffic surge, not DDoS attack: IMDA

SINGAPORE (April 24): The Infocomm Media Development Authority (IMDA) says StarHub’s home broadband network disruptions in Oct last year were caused by a surge in legitimate Domain Name System (DNS) traffic, and not a Distributed Denial of Service (DDoS) attack as initially suspected.

In a press release on April 21, IMDA says its in-depth investigation, held together with the Cyber Security Agency of Singapore (CSA), “did not uncover any evidence to suggest that the cause of the incidents was a DDoS attack on StarHub’s network infrastructure”.

Instead, further analysis showed StarHub’s home broadband infrastructure was overloaded due to a higher-than-usual increase in traffic largely driven by legitimate DNS requests.
