All umami instances have been infected with a persisting crypto miner.
Source for that claim? Because vulnerable does not mean infected.
Also, I'm kinda glad my instance has been offline for a while now because of database trouble. That was lucky.
I don’t know about “all umami instances being infected” but they were certainly all vulnerable.
Link? Did you discover this yourself? There is no actual info here.
All recently open issues are about this. I was a victim, but I'm not the first and people on reddit have done better investigations than I have. Look for the name of the process at the top
Thanks.

Admins in self hosted usually don't have that much experience with real, active compromise and may panic, let's help them as much as possible.
I will add that Umami itself is not compromised, but vulnerable. That is a somewhat misleading title.
What was the vector? Did you have umami exposed publicly?
I see it's running Ansible. That's an obvious risk.
