5 Fediverse sites have been hacked due to running outdated software.

Please take a moment to ensure that your instance of Mastodon, Misskey, PeerTube, PixelFed, or any other Fediverse platform is fully up-to-date.

It may also be wise to log into your server and update your operating system.

Debian / Ubuntu servers:

sudo apt update
sudo apt dist-upgrade
sudo reboot

Fedora / CentOS / Red Hat / Alma Linux:

sudo dnf update --refresh
sudo dnf upgrade
sudo reboot

If you update your OS, your server will be briefly offline during the reboot. If you have not configured your web services — including your Fediverse service — to start automatically on boot, you may need to start them manually afterward.

Always make a backup before performing upgrades.

If any of this is confusing or feels overwhelming, you should reconsider whether you want to be a server administrator. This is not meant as an insult. It’s great that you wanted to contribute to the Fediverse, but you may be better off participating as a user rather than an admin. People depend on you to keep services running smoothly, and that requires knowing how to maintain your system safely and correctly.
