Find running binary executables that were not installed using dpkg

This helped me find a botnet that had made into my system. Of course, this is not a foolproof or guarantied way to find all of them or even most of them. But it helped me find it.

Really useful, thanks!

This causes the ram memory to fill up on my machine. So I did this:

cat /var/lib/dpkg/info/*.list | egrep -v '\.(desktop|html|gz|xpm|png|jpg|svg|gif|css|xml|icon|glade|map|md5|tmpl|sample|h|c|rc|m4|mo|data2|ui)$' > /tmp/listin ; ls /proc/*/exe | xargs -l readlink | grep -xvFf /tmp/listin; rm /tmp/listin

Well, I just realized how not foolproof this is. There was one more botnet whose directory name was just a space. (yeah that one " ").

Can someone come up with a much better command (full input sanitization).

Never mind my previous comment. When I was trying out again, I had missed giving the '-l' option to xargs.

Weboide: please submit your command as an alternative

This works on Arch Linux:

ls /proc/*/exe | xargs -L1 readlink | while read line; do if ! pacman -Qo "$line" > /dev/null; then echo $line; fi;
