I have a droplet running ubuntu 16.04 with apache and mysql. I have hosted a wordpress website on this server which was running fine. But week ago mysql was stopped working automatically. which when I later examine and found that a process running on my droplet using all the cpu. This process is cache.sh which is using 98% of cpu, because of which apache and mysql stopped working. When i kill the process it starts again. I can’t find any solution to kill this process permanently or secure my site from such attacks. It looks like it is a crypto mining malware which is using all resources to mine crypto currency. How should I stop and block this process. Please help.
