First Successful Collision Attack On the SHA-1 Hashing Algorithm (google.com)

Artem Tashkinov writes: Researchers from Dutch and Singapore universities have successfully carried out an initial attack on the SHA-1 hashing algorithm by finding a collision at the SHA1 compression function. They describe their work in the paper "Freestart collision for full SHA-1". The work paves the way for full SHA-1 collision attacks, and the researchers estimate that such attacks will become reality at the end of 2015. They also created a dedicated web site humorously called The SHAppening.

Perhaps the call to deprecate the SHA-1 standard in 2017 in major web browsers seems belated and this event has to be accelerated.
