I love the fact that there is a tool for detecting any collision using this algorithm: https://github.com/cr-marcstevens/sha1collisiondetection https://github.com/cr-marcstevens/sha1collisiondetection and it's super effective: The possibility of false positives can be neglected as the probability is smaller than 2^-90. It's also interesting that this attack is from the same author that detected that Flame (the nation-state virus) was signed using an unknown collision algorithm on MD5 (cited in the shattered paper introduction).
