Julian Wälde and Alexander Klink will be presenting a new attack against Web Application Frameworks (WAF), that can be used to generate HTTP requests, that take several minutes of CPU time to process. Sending many of these requests in parallel can be used as an effective Denial of Service attack against many websites. Even one cannot spot any relation to cryptography from the abstract, I have been informed that this talk will also cover many cryptography related aspects.
