It has been reported that two academics from the Technical University of Cologne (TH Koln) have disclosed a new type of web attack that can poison content delivery networks (CDNs) into caching and then serving error pages instead of legitimate websites.

The new attack has been named CPDoS (Cache-Poisoned Denial-of-Service), has three variants, and has been deemed practical in the real world (unlike most other web cache attacks).
