judgecorp writes "During last week's Zimbabwean election, some huge denial of service attacks took down sites including several reporting on human rights issues and potential irregularities in the election. Those affected suspect government involvement. ... GreenNet is only just recovering today, with some customer websites still down, having reported the strike on Thursday morning, the day after Zimbabweans headed to the polls. It appeared to be a powerful attack – TechWeek understands it was at the 100Gbps level – aimed at GreenNet’s co-location data centre provider Level 3, which subsequently did not let GreenNet move workloads within that facility. ... The DDoS that hit GreenNet was not a crude attack using a botnet to fire traffic straight at a target port, but a DNS reflection attack using UDP packets, which can generate considerable power. DNS reflection sees the attacker spoof their IP address to pretend to be the target, send lines of attack code to a DNS server, which then sends back large amounts of traffic to the victim."
