uep | and i'm sure at some point this is going to be a new attack against matrix servers when those are too long | 07:59:13 |
Cat | In reply to @uep:matrix.org but it doesn't apply to invites, and there's no real way for clients to use them, and the format is a bit limited so you can't use things like patterns for usernames There’s tech that’s rapidly maturing into stable releases that deals with this tho. | 08:00:08 |
Cat | It’s tho a ask your homeserver admin | 08:00:19 |
Zhaofeng Li | Has there been any discussion about moving to... libera.chat? I know we will essentially be moving "back" but still | 08:00:36 |
Cat | Draupnir has in beta the capability to pre emptively with HS support block known bad invites and clean them up also | 08:01:06 |
Cat | And there has already been work started on implementing the policy server backend in meowlnir and I wouldn’t be shocked if it lands in Draupnir eventually too | 08:02:28 |
uep | meowlnir.. lol | 08:03:23 |
Cat | Tulir loves cats. | 08:03:43 |
emily | to be clear, this is the second phase | 08:05:15 |
emily | the first phase was joining the rooms directly and spamming CSAM/gore | 08:05:22 |
emily | coupled with DoS targeting federation so that deletion events for the messages didn't get propagated quickly | 08:05:38 |
emily | (and even when they do, homeservers and clients don't purge media from caches by default on deletion, so it's too late to prevent illegal material propagating to the storage of hundreds of machines) | 08:06:11 |
emily | that's why we went invite only | 08:06:17 |
emily | the invite spam is quite a bit less bad than that was frankly | 08:07:32 |
Zhaofeng Li | In reply to @emilazy:matrix.org (and even when they do, homeservers and clients don't purge media from caches by default on deletion, so it's too late to prevent illegal material propagating to the storage of hundreds of machines) on that note, what's the solution now? I think a few years back we were sharing media IDs to be deleted manually | 08:09:38 |
uep | for the most part it's just "delete remote images" from the cache.. and hope the spammers aren't your own users | 08:11:16 |
uep | which of course has other impact on genuine users and content, so the spammers win regardless | 08:11:51 |
