Shared mail DDoS – ExchangeDefender Network Operations

Shared mail DDoS

Filed under: Virtual Hosting — admin @ 5:58 pm

From approximately 10 AM – 2 PM EST, our shared mail hosting platform (mail1.ownwebnow.com) suffered a large scale distributed denial of service attack (DDoS). Everything is under full control now and we have been able to filter out the offending systems. Unfortunately, there is little that can be done in terms of scale and protection against a DDoS as we already have both Cisco and Tipping Point in place.

DDoS attacks tend to be flared up by the regular user activity, as the system slows down end users keep clicking Send/Receive and effectively flood the connection until it times out. Systems are back to normal and messages are starting to arrive in regular sequence.
