Re: Weird server mystery: self-reset, mostly



That's quite an assertion. How can I confirm it HAS been compromised, as opposed to thinking it's a possibility?

There is no mistery.  Your system has been compromised.  Get post-mortem
backups done for forensic purposes, wipe the box, and proceed to a full
reinstall.

Kindly don't leave that thing connected to the network for now, as it is
likely being used as a botnet C&C node, or as an attack platform.

Based on the uptime and "debian_version" data you provided, whomever
takes care of that system has been very negligent with security updates.
It is no wonder it got rooted.  Let that be a lesson for the future.
