While reading over my logwatch report this morning I found this one entry for Init:
---------------------- Init Begin -------------------------
**Unmatched Entries**
Trying to re-exec init
---------------------- Init End -------------------------
I checked out /etc/inittab for any changes, tripwire reported lots of changes, but just yesterday I used up2date on glibc and nscd and didn't reinitialize the tripwire db. So that explains the lot of them.
Also I noticed nscd added a config file under /etc/rc.d/init.d so I was wondering if its normal for either of these updates to re-exec initd or if I should be more concerned.
While digging I found someone checking an email account that shouldn't be. The person has obviously sniffed this users pass because there was no brute-force attack and now he was steadily checking the POP3 box. So I went ahead and changed the users pass and added the host to iptables.
Is there anything I should do? Did I look in the right places?
Thanks
