If you are using one of the *oma instances (Akkoma, Pleroma, etc): you can easily handle this spam wave without playing defederation whack-a-mole by doing the following:

• Enable RejectNewlyCreatedAccountNotesPolicy and set the limit to at least one hour. Note that this is not without tradeoffs: users who migrate to new accounts will not be able to reach your instance until their account is old enough, and will often wonder what’s going on.
• Enable HellthreadPolicy to limit the maximum number of mentions in a post before it stops notifying mentioned users, or before it’s rejected outright. Temporarily decrease the limit during a spam wave if you need to.
• Enable KeywordPolicy and add strings commonly found in spam posts, such as domain names (followed by a slash, to reduce false positives from real users simply mentioning the domain without linking it), hashtags, and uncommon words. Look up the “Scunthorpe Problem” if you’re unfamiliar.

When the dust settles, depending on available spoons, I might go through the instances that haven’t cleaned up spam after multiple days. Those are likely abandoned and extra-vulnerable to future attacks and block evaders. On *oma, these defederations will not sever connections and are reversible.

Hello all Fedi Admins who have problems with spam!

The Mute List 2.2.2

I have been updating the spam list and found ~104 additional instances that continued spamming! I, with lots of help of other Fedi Admins, have compiled the instances into a list which mutes them, and does not defederate from them!

I'd highly appreciate a small donation here as I've worked really hard and long on creating this, which given my current schedule I can hardly justify! Thanks!

There is a new type of spam, the same instances are affected as before. Those responsible in Japan are said to have been arrested.

Download the list here.

Instructions and Explanation of the List.

Once this list is imported, most of the spam is gone. The whole thing is easy for you, with just one click! In addition, no instance is blocked forever, no followers etc. are destroyed or unfollowed, only muted.

You can simply import this list by going to https://yourinstance.tld/admin/export_domain_blocks/new and replacing yourinstance.tld with the domain of the instance you are the administrator of!

Alternatively, you can also click on Settings => Moderation => Federation => Import to import this list.

Note that although all instances can be imported with one click, these instances must be removed individually when the spam is over.

Also note that it only makes sense to import this list and mute the spam instances if you have blocked your spam locally and permanently, as described here.

Here's to a spam-free Fediverse :apartyblobcat: !

Hallo alle Fedi-Admins die Probleme mit Spam haben!

Die Mute-Liste 2.2.2

Ich habe die Spam-Liste aktualisiert und ~104 zusätzliche Instanzen gefunden, die weiterhin spammen! Ich habe, mit viel Hilfe von anderen Fedi Admins, die Instanzen in einer Liste zusammengestellt, die sie stumm schaltet und nicht von ihnen deföderiert!

Ich würde mich sehr über eine kleine Spende hier freuen, da Ich wirklich hart und lange an der Erstellung dieser Liste gearbeitet habe, was Ich angesichts meines aktuellen Zeitplans kaum rechtfertigen kann! Dankeschön!

Es gibt eine neue Art von Spam, die gleichen Instanzen sind betroffen wie vorher. Die Verantwortlichen in Japan sollen verhaftet worden sein.

Downloaded die Liste hier.

Anleitung und Erklärung zur Liste.

Ist diese Liste importiert ist ein Großteil des Spams vorbei. Das ganze ist für euch leicht, geht mit einem klick! Zudem wird keinerlei Instanz für immer geblockt, keinerlei Follower etc. zerstört oder deföderiert, sondern nur stummgeschaltet. Das ist sehr leicht umkehrbar.

Ihr könnet diese Liste einfach importieren, indem ihr auf https://yourinstance.tld/admin/export_domain_blocks/new geht und yourinstance.tld durch die Domain derer Instanz ersetzt, von der ihr der Administrator seid!

Alternativ könnt ihr auch auf Einstellungen => Moderation => Föderation => Importieren drücken, um diese Liste zu importieren.

Beachtet, dass zwar alle Instanzen mit einem Klick importiert werden können, dass aber diese Instanzen einzeln entfernt werden müssen, wenn der Spam vorbei ist.

Beachtet auch, dass es nur Sinn ergibt, diese Liste zu importieren und die Spam-Instanzen stumm zu schalten, wenn ihr euren Spam lokal und nachhaltig blockiert habt, wie hier beschrieben.

Auf ein Spam-Freies Fediverse ​ !

Woha, this is unexpected: in a future update mastodon will automatically turn off open registration if no mod has logged in for a week or longer:

github.com/mastodon/mastodon/p…

This is great news, and should hopefully significantly cut down on abandoned servers being used to send spam!

(And this is in addition to also having open registrations off by default on new servers.)

Great news!

This makes me furious. Please, stop using Discord. They are complicit if they keep the discord server responsible for keeping the spam attacks alive.

Are you seeing spam? A poll

The fediverse is dealing with a major spam attack -- Heise has some coverage (in German).

But not everybody is seeing spam. Are you? If so how much?

summary of today:

someone on a Japanese hacker forum decided it was a good idea to spam the entire Fediverse because they wanted to cancel a minor that DDoSed a Discord bot which apparently made them lost millions (what?)

A Discord bot. I can't make this shit up man.

The real culprit seems to be someone who goes by mumei in the ctkpaarr.org forums, whose first post was literally a threat to ap12, that if they don't delete their "Kuroneko Server" Discord bot, they will spam every blog, forum and SNS and cancel him.

This shit is ridiculous.

The ap12 account from mastodon-japan was actually fake, and this dude impersonated a minor to get all of the Fediverse (us) to bully him.

The forum admins didn't even stop this. Why? lulz apparently. #fediblockmeta#fediadmins#fediadmin#mastoadmin#mastoadmins#spam#cybercrime#cybersec#infosec#drama#discord

Resolved: Microsoft Outlook Blocking All Email from @tutanota.com Domain as Spam.

tuta.com/blog/outlook-falsely-…

This is just another example of how much power Microsoft has. But sometimes I'm not sure they really know what they're doing.

Anyway, dealing with Windows email users (businesses and individuals) can be a nightmare.

If you plan on using your own email server, sooner or later you'll be playing this game too.

I have banned and purged sbcloud.cc from everywhere, based on this

2023-01-29T10:27:59Z worker [INFO]: Server peer update start {"url":"https://fed.sbcloud.cc","worker_id":"85e31dd","worker_cmd":"UpdateServerPeers"} - {"file":"UpdateServerPeers.php","line":54,"function":"execute","uid":"a33038","process_id":295381}

Since then worker doesn't pull in spambots again.

Now, it would be neat to know:
1. What exatly happened (I don't know the protocol that deeply)
2. Who did what
3. How to prevent that from happening in the future (both network-wise and locally)
