【Security News】Open Rsolvers used to amplify DDoS attacks

Dear Valued Customer,

 

Thank you for using Tsukaeru.net

 

Recently, DDoS amplification attacks has increased by Open Rsolvers.

 

There is a possibility of DDos attack that the customers who use own name server and /or use Plesk.

So we strongly recommend to take appropriate security measure.

*DDoS attack

 

Short for denial-of-service attack, a type of attack on a network that is designed to bring the network to its knees by flooding it with useless traffic. Many DoS attacks, such as the Ping of Death and Teardrop attacks, exploit limitations in the TCP/IP protocols. For all known DoS attacks, there are software fixes that system administrators can install to limit the damage caused by the attacks. But, like viruses, new DoS attacks are constantly being dreamed up by hackers.

 

■Target:

 

Customers who use VPS, Dedicated server, Cloud server with Plesk

and / or use own nameserver

 

※Attention※

 

・Customers who use Windows VPS for FX since February, 2011 does not affect DDos attack.

・Customers who use shared server does not affect on this issue.

Security measure has already done by Tsukaerunet.
