After having hit various online game services and big-shot sites like Twitter, Meetup and EA Sports, the cyber miscreants aimed at WizIQ, resulting in a distributed denial of service or DDoS attack. We think this was around the same time when Basecamp was hit in a similar way.
Although there has been no apparent design detected, these attacks are generally executed with malicious intent (sometimes for extortion, other times for harassment); aiming to disrupt the peaceful operations of a web-based service provider like ours.
BBC News reported earlier this year that post the Derp Trolling hack incident, DDoSers have found new flaws in the old NTP system, thus finding new ways to overwhelm servers with huge data.
It was a Network Time Protocol (NTP) attack. There was an inflow of 20Gbps of extra data into our servers. In order to avoid any cyber theft of your personal information, we brought down the servers.
We apologize to all the teachers and students whose teaching and learning suffered! As of now we are up and running, but we are still investigating the attack. We are taking all preventive measures and consulting with the best in the field to analyse the attack and defend our users from any future disruption.
We will keep you posted as and when we come up with the complete analysis of the attack. We sincerely appreciate your support and patience. In case you have any queries, feel free to get in touch at email@example.com.
