"We have anticipated these flaws in DNS for many years and we have basically engineered around them," Ken Silva, chief technology officer at Verisign, told a reporter as Dan Kaminsky (pictured), the man who discovered a loophole in the DNS system that allows web users to be redirected to fake sites even when they have typed in the correct URL, spoke out yesterday publicly for the first time about his discovery at the Black Hat conference in Las Vegas.

Kaminsky has spent the better part of a decade analyzing computer security issues with the Fortune 500. Formerly of Cisco and Avaya, he is presently the Director of Penetration Testing for IOActive, Inc., where he consults for a wide range of companies, including Microsoft. He is a well known public speaker, with his “Black Ops of TCP/IP” presentations being well attended at many conferences.

Software companies across the industry have quietly collaborated to simultaneously release fixes for all affected name servers. To find out if the DNS server you use is vulnerable, click below."
