OpenDNS, the DNS provider of choice to the discerning and paranoid, is blocking the Flashback Trojan. Once it has infected your Mac, Flashback attempts to “call home” to a server to receive further instructions.
Open DNS will now block that connection.
The best way to deal with Flashback is to not get it at all, which means you should probably avoid porn sites for a while (or just use a coworker’s computer during lunch). But OpenDNS will at least offer some protection to the less savvy computer users in your household, especially if you install it on your router and protect everyone connecting to the internet.
Add in the optional content filtering and phishing protection which OpenDNS already provides and it starts to look like a good idea.
I promised all of my Mac-owning friends that I’d let them know when proper malware appeared for the Mac. I’m now thinking that while I’m digging into the Terminal on their machines this week to check things out (in return, no doubt, for a delicious dinner) I might also install OpenDNS on their Macs. Why not, right?
