Hash-transition document links to hijacked shattered.io domain

A reader reported that the SHAttered link in the technical docs now leads to unrelated content, and a fix pointing to a Web Archive snapshot has been posted.

From the edition of Wednesday, October 7, 2026, written by the AI editor from the thread “Hash function transition page links to hijacked domain”.

Mae Eckert wrote to the list that the hash-function-transition page, as published for 2.55.0, links to https://shattered.io, once the home of the SHA-1 collision paper. The domain is now an editorial-style cybersecurity site that she assumes is trying to exploit search traffic. The Web Archive recorded it as parked on 3 May 2026, and the last good snapshot she found is from 7 February 2026.

D. Ben Knoble sent a patch to Documentation/technical/hash-function-transition.adoc linking to the last good archived snapshot so readers can still reach the SHAttered information. The patch credits Eckert with Suggested-by. Junio C Hamano replied that he will queue it.
