After the massacre at the mosque on New Zealand, Microsoft’s president published a blog post in which he said, among other things, that:
We should also pursue new steps beyond the posting of content. For example, we should explore browser-based solutions – building on ideas like safe search – to block the accessing of such content at the point when people attempt to view and download it.
This implies that the hashes of content to be blocked would be distributed to every client.
As far as I know, today the hashes for flagged files are closely guarded. Is it a good idea to distribute them? Does not making them public make it easier for bad actors to evade detection?
