Three Days in August: What a DDoS Attack Exposed in Our Network

Nine's network experienced a DDoS attack in August 2026, revealing a vulnerability in the company's network architecture. The attack was detected and mitigated within three days, with the company's system engineers working around the clock to contain the issue. The attack was later determined to be a distributed denial-of-service (DDoS) attack, which is a type of cyberattack that aims to make a network resource unavailable by overwhelming it with traffic from multiple sources. The company's system engineers discovered that the attack was coming from a botnet of compromised IoT devices, which were used to flood the company's network with traffic. The attack was eventually mitigated by blocking the traffic at the network edge, and the company's system engineers worked to patch the vulnerability that allowed the attack to occur in the first place. The company has since implemented additional security measures to prevent similar attacks in the future.
