Speaking of SHA-3, "biclique cryptanalysis was first introduced for hash cryptanalysis". Here's an interesting quote from the paper regarding the relationship between attacks on block ciphers and hash functions:

"... the block cipher standard AES is almost as secure as it was 10 years ago in the strongest and most practical model with a single unknown key. The former standard DES has not seen a major improvement since Matsui’s seminal paper in 1993.

In contrast, the area of hash function cryptanalysis is growing quickly, encouraged by the cryptanalysis MD5, of SHA-0 and SHA-1, followed by a practical attack on protocols using MD5, preimage attacks on Tiger and MD5, etc. As differential cryptanalysis, a technique originally developed for ciphers, was carried over to hash function analysis, cryptanalysts are now looking for the opposite: a hash analysis method that would give new results on block ciphers."
