It seems you could be owned by someone, maybe due to a combination of a
web-app vulnerability which led to an apache shell which led to a
kernel exploit execution, which led to root, which led to executing
whatever, in that case, making your machine to be a spammer zombie or
so. You know, the usual shit nowadays.

Run the usual tools, chkrootkit, rkhunter, etc.

Good luck.
