You might find lines in your logs like:
Apr 1 09:25:01 server su[30315]: + ??? root-nobody
Apr 1 09:25:01 server PAM_unix[30315]: (su) session opened for user nobody by (uid=0)
Don't worry too much, check out if this is due to a job running through the cron (usually /etc/cron.daily/find or logrotate):
$ grep 25 /etc/crontab
25 6 * * * root test -e /usr/sbin/anacron || run-parts --report
/etc/cron.daily
$ grep nobody /etc/cron.daily/*
find:cd / && updatedb --localuser=nobody 2>/dev/null
