Sincere apologies in advance if this has already been posted. I have done several searches using various combinations (DNS, hijacking, addressing etc) and couldn't find anything... But if there hasn't already been a thread I'm quite surprised tbh 
Anyway...
Quite an interesting read, and the article contains a link to the website of the exploit's discoverer which contains a vulnerability checker for your own DNS. OpenDNS scans clean, but I haven't checked UK Online's. Has anybody else seen this? I'm no DNS expert but this could have caused a great deal of confusion (not to mention massive financial losses) had it broken into the wild.

Anyway...
The Times' HP Sauce.Internet giants have united to fix a serious flaw in the internet addressing system that might have let hackers hijack web traffic.
The big software and hardware makers worked in secret for months to create a software patch which has now been released to repair the glitch.
The flaw, discovered by accident, would allow criminals to redirect users to fake webpages, even if they typed the correct address into a browser. Dan Kaminsky, a security researcher at IOActive, stumbled upon the vulnerability in the domain name system (DNS) about six months ago and contacted industry giants including Microsoft, Sun Microsystems and Cisco to collaborate on a solution.
