from /etc/crontab:

	# m h dom mon dow user  command
	25 6    * * *   root    test -e /usr/sbin/anacron || run-parts --report /etc/cron.daily

which then in turn invokes:

	/etc/cron.daily/find

which contains the line:

	cd / && updatedb --localuser=nobody 2>/dev/null

and from the manpage for updatedb, you'll see that --localuser invokes su.
:)

In short, this appears to be normal daily processing on your system.
