SHAttered is a term used for SHA-1 having a Cryptographic Collision

Cryptographic Hash Functions like SHA-1 are a cryptographer’s swiss army knife.

Cryptographic Hash Functions play a role in browser security, managing code repositories, or even just detecting duplicate files in storage. Cryptographic Hash Functions compress large amounts of data into a small Message-Digest.

As a cryptographic requirement for wide-spread use, finding two messages that lead to the same Message-Digest should be computationally infeasible. Over time however, this requirement can fail due to attacks on the mathematical underpinnings of Cryptographic Hash Functions or to increases in computational power.
