Cryptanalysis of the hash functions MD4 and RIPEMD
TL;DR: In this article, a chosen-message pre-image attack on MD4 with complexity below 28 was presented, where the complexity is only a single MD4 computation and a random message is a weak message with probability 2−2 to 2−6.

Collisions for Hash Functions MD4, MD5, HAVAL-128 and RIPEMD
TL;DR: In 1993 Bert den Boer and Antoon Bosselaers found pseudo-collision for MD5 which is made of the same message with two different sets of initial value.

Cryptanalysis of the hash functions MD4 and RIPEMD
TL;DR: In this article, a chosen-message pre-image attack on MD4 with complexity below 2 8 was presented, and for a weak message, the complexity is only a single MD4 computation, and a random message is a strong message with probability 2 -122.
