After the MD5 disaster and related breakthroughs in hash cryptanalysis, the cryptologic community as well as practitioners are searching for a trustworthy next generation hash function standard. This culminated in a large international multi-year effort, the SHA-3 competition, planned to end in 2012. In this talk we survey the remaining candidates in this competition and discuss how this competition led to a new way of doing hash cryptanalysis: the rebound attack. AES-like proposals were first targets because of their simplicity. Recently we started to apply this method also to very different constructions, and consistently get results that beat the best known attacks. We survey those results, and comment on their impact on the outcome of the SHA-3 competition.
