Perhaps it's just paranoia from my days of Win admin but I never completely trust a system that has been breached.
So I'd be looking to migrate your data to a new server. If you have a recent backup (eg TKLBAM prior to breach) I'd restore that to a brand new clean appliance. If you don't have that, then you could try doing a TKLBAM backup and just restore the data (files and database - I'd exclude any packages).
Something you could look into to increase security is using keyfile SSH logins and disable passwords (you'll need to do a little searching on config because I don't recall OTTOMH).
Personally I'd be looking to start fresh...
