Shattered: The first collision for full SHA-1, by Marc Stevens, Elie Bursztein, Pierre Karpman, Ange Albertini, and Yarik Markov. “We were able to find this collision by combining many special cryptanalytic techniques in complex ways and improving upon previous work. In total the computational effort spent is equivalent to 263.1 SHA-1 compressions and took approximately 6500 CPU years and 100 GPU years.”
