Kudos to OpenDNS for Catching 1-millionth Phish

Ken Harthun Ken Harthun Profile: Ken Harthun

On August 13, 2010, David Ulevitch, Founder & CEO of OpenDNS announced in a blog post that their community-driven site,, had just caught its 1-millionth phish: “Today I’m excited to announce that the 1 millionth phish has been submitted to PhishTank. The “winning” submission was a fake Citibank UK website, which was quickly verified by the PhishTank community,” he wrote.

I’ve written about OpenDNS before: DNS rebinding defenses still necessary, thanks to Web 2.0, at in Jul. 2008; OpenDNS Service to Track and Block Conficker Worm, here in Feb. 2009; and, Top Ten Security Tools at in Apr. 2009. Most recently, I posted How to Combat Phishing Attempts on Sep. 3, 2010, mentioning OpenDNS as a tool to help combat phishing attempts. I’ve never mentioned PhishTank before, so I think it’s time I did.

Using OpenDNS means you and your network are protected against phishing attempts. One of the ways we identify which sites are fraudulent, and which ones are legitimate, is through, the community-driven site we operate that we’re proud to report is the world’s largest and fastest-moving clearing house of phishing data.

OpenDNS launched the site four years ago in October of 2006 to create a clearinghouse for phishing data that could be made available to other services via an API. At the time, there was no existing common source of phishing data that was fast-moving, accurate and reliable. I’m a member, and I hope you’ll consider joining. It is an important contribution to the entire web community and, unlike many community sites out there, the OpenDNS people realize this and appreciate their community members:

Thank you to the thousands of security pros, researchers, academics and concerned Internet users for their contributions to PhishTank. It’s you who have made this possible. You’ve protected tens of millions of people around the world, lending your expertise to help take the guesswork out of identifying phishing scams. It’s a credit to the community that we’ve reached this milestone. And in doing so, we’ve together helped protect not only people who use OpenDNS, but millions more, since the phishing scams reported and verified are also blocked by all of the Internet services PhishTank shares the data with.
