There have been numerous examples of tampering, or man-in-the-middle attacks, and snooping of DNS traffic at the last mile and it represents a serious security risk that we've always wanted to fix. As the world’s Internet connectivity becomes increasingly mobile and more and more people are connecting to several different WiFi networks in a single day, the need for a solution is mounting.
DNSCrypt is our way of securing the "last mile" of DNS traffic and resolving (no pun intended) an entire class of serious security concerns with the DNS protocol. That said, the class of problems that the Kaminsky Vulnerability related to were a result of some of the underlying foundations of the DNS protocol that are inherently weak - particularly in the "last mile." The "last mile" is the portion of your Internet connection between your computer and your ISP.
Many will remember the Kaminsky Vulnerability, which impacted nearly every DNS implementation in the world (though not OpenDNS). While OpenDNS has provided world-class security using DNS for years, and OpenDNS is the most secure DNS service available, the underlying DNS protocol has not been secure enough for our comfort. It's used any time you visit a website, send an email, have an IM conversation or do anything else online.
