Oh, AFP

That DNS flaw that we mentioned a few days ago has been discovered by “hackers,” and is currently being “weaponized,” says a top Internet security expert.

The attack makes use of cache poisoning to re-direct traffic. Worst case scenario, you try going to yourbank.com, but instead are taken to a hacker’s phishing site. You put in your account details and bam, they now have your info. It’s potentially pretty serious.

Says the concerned security dude:

We are in a lot of trouble…. Everyone needs this patch, please. This is a big deal.

You can check to see if your ISP has applied the patch here, and if they haven’t—mine here in Spain hasn’t—you may want to use OpenDNS, which is safe as can be.
