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.
Nope, just like Reddit it’s a value that ranges between negatives and positives. If I get two thousand upvotes, positive 2k. If I get two thousand downvotes, negative 1999 (because iirc you start with one by default).
Not exactly sure I understood what you meant by “either positive or zero”.
see your comment rn, it has 1 upvote (from yourself by default) and 0 dislike (so it’s not shown)
but in the screenshot I sent above you got 287 upvote and minus -1 downvote (making your total 288) which is mathematically correct but seems like an unintended behavior
for example this comment of mine normally have 9 upvote and 2 downvote (which is shown as a positive integer 2, not negative), making my total upvote 7
Just occurred to me that the app I use also shows separate counters. I fooled myself into thinking it was a single counter.
That’s interesting. Remember it’s a very new platform, minor bugs aren’t out of the ordinary.
