DNS troubles Down Under
According to an Australian security company, over 75 percent of the DNS servers in Australia are vulnerable to DOS attacks, and 55 percent are vulnerable to security exploits that could give root access to intruders. Take a look at this ZDNet article for the complete story. Worse, it appears that the problems could be fixed by the installation of a software patch, but some companies haven't updated their DNS servers in six years or more. Ouch.
The article goes on to point out a range of problems that this could conceivably cause, from the obvious service outage from a DOS attack, to a domino effect of compromised systems due to some companies basing trust relationships on host name. Hopefully this will be a good wake-up call, but now that the story has broken, I'm sure there are loads of hackers out there trying security exploits on any Australian server they can find.
