The hash function Blue Midnight Wish (BMW) is a candidate in the SHA-3 competition organized by the U.S. National Institute of Standards and Technology (NIST). BMW was selected for the second round of the competition, but the algorithm was tweaked in a number of ways. In this paper the authors describe cryptanalysis on the original version of BMW, as submitted to the SHA-3 competition in October 2008. The attacks described are (near-) collision, preimage and second preimage attacks on the BMW compression function.
