Misconfigured Open DNS Resolvers Key To Massive DDoS Attacks 179

Posted by Unknown Lamer from the check-your-sources dept.
msm1267 writes with an excerpt From Threat Post: "While the big traffic numbers and the spat between Spamhaus and illicit webhost Cyberbunker are grabbing big headlines, the underlying and percolating issue at play here has to do with the open DNS resolvers being used to DDoS the spam-fighters from Switzerland. Open resolvers do not authenticate a packet-sender's IP address before a DNS reply is sent back. Therefore, an attacker that is able to spoof a victim's IP address can have a DNS request bombard the victim with a 100-to-1 ratio of traffic coming back to them versus what was requested. DNS amplification attacks such as these have been used lately by hacktivists, extortionists and blacklisted webhosts to great success." Running an open DNS resolver isn't itself always a problem, but it looks like people are enabling neither source address verification nor rate limiting.

Comment Re:Arch Linux: what's the differentiating factor? (Score 1) 103

by bjoast (#38725904) Attached to: Package Signing Comes To Pacman and Arch Linux

Because of the AUR, Arch is more likely to have a package for some given obscure application that Debian would be missing. Also, these packages are kept up to date to a greater extent than you'll see on Debian. Finally they're all in one place where as you don't have to constantly add repositories to your package manager's repo list.

What you're mentioning are some of the main reasons why I am running Arch. But there's also the wiki, the community and the feeling of having a system which is very simple and clean. I tried it a few months ago and just loved it.

An anonymous reader writes: Apple will likely introduce the iPhone 5 at an upcoming special media event on October 4, ending months of speculation as to when the Cupertino-based company would finally unveil its 5th generation iPhone.

And for the first time since the original iPhone was introduced in 2007, Steve Jobs will not be handling the introduction. Indeed, that will now be handled by newly minted CEO Tim Cook.

North Korea has long denied the existence of prison camps in its supposed utopia, but even as far back as 2004 The Guardian was reporting that the camps held an estimated 200,000 citizens. 50,000 of them, all deemed enemies of the state even though many had been actually born inside, are in North Korea’s most notorious hell, Camp 22."
