DNS NXNAattack bug

Hi All

 

Another attack on poor old DNS:  It is hard to believe in this technological world, we remain reliant on this insecure service.

 

"Dubbed NXNSAttack, the flaw [PDF] can be abused to pull off a classic amplification attack: you send a small amount of specially crafted data to a DNS server, which responds by sending a lot of data to a victim's server. If you have an army of hacked PCs or devices – a botnet – at your command, and can find a DNS service that's vulnerable, you can theoretically generate enough network traffic to overwhelm a victim's system and knock it offline for all users."
