DDoS weighing in at nearly 400Gbps targets unnamed CloudFlare customer in Europe, as attackers use NTP to amplify attack
The European attack used NTP amplification which involves exploiting the UDP-based Network Timing Protocol.
CloudFlare CEO wrote:Despite its apparent strength, there does not seem to have been any serious downtime as a result of the DDoS, unlike the Spamhaus attacks, which took out a swathe of sites. “There was extra latency in Europe. Overall, network was unaffected,” said Matthew Prince, CEO of CloudFlare.
So it looks like a bit of a damp squib, really.
