SQL injection and out-of-band channeling

Presented at DEF CON 15 (2007), Aug. 3, 2007, 11 a.m. (50 minutes).

A large number of web applications are still found suffering from improper input validation controls. This is a fact commonly exploited by hackers in order to gain unauthorized access to backend databases and steal sensitive corporate information. As systems are hardened hackers are often forced to rely on blind SQL injection in order to extract information. The audience will be introduced to out-of-band channeling, an alternate technique which under certain circumstances can be much more efficient in achieving the task. A number of different channels, pros & cons and preventive measures will be presented. Did you know a hacker could steal your corporate secrets by channeling them over DNS?
