While I was asleep, apparently the site was hacked. Luckily, (big) part of the lemmy.world team is in US, and some early birds in EU also helped mitigate this.

As I am told, this was the issue:

There is an vulnerability which was exploited
Several people had their JWT cookies leaked, including at least one admin
Attackers started changing site settings and posting fake announcements etc

Our mitigations:

We removed the vulnerability
Deleted all comments and private messages that contained the exploit
Rotated JWT secret which invalidated all existing cookies

The vulnerability will be fixed by the Lemmy devs.

Details of the vulnerability are here

Many thanks for all that helped, and sorry for any inconvenience caused!

Update While we believe the admins accounts were what they were after, it could be that other users accounts were compromised. Your cookie could have been 'stolen' and the hacker could have had access to your account, creating posts and comments under your name, and accessing/changing your settings (which shows your e-mail).

For this, you would have had to be using lemmy.world at that time, and load a page that had the vulnerability in it.

You're ruining the circlejerk with your realism! 😠

Edit: I think Mr. Robot gave a good glimpse what would happen if all debts were wiped. It sounds fun on paper, but in the end, the people with the least money would suffer the most.

I personally just lose any interest in conversation when I realize that my counterpart doesn't want a working system or a better world or really some justice, they simply want to rob someone who has more than they do. No deeper purpose or something, just plain envy.

It's like certain moments in sex. So bloody frustrating.

And, of course, the only leftists I've encountered who wouldn't be what I describe were book characters. Yeah, nice characters, fascinating, really making me wish something like this was possible, but even with the depth limitations for describing an entire person on paper they were still deeper that RL leftists, FFS!!!

I have at least met living sincere good-willing ancaps and living sincere good-willing fascists (sic) even. The only people I know in person I could possibly call a real sincere good-willing leftist would be my sister, and maybe one of my cousins, and one DM (though from a few conversations I suspect he just has, eh, a leftist background, but is more literate in economics than such people usually are).
