Cleaning up Cypto Miner Infection on ubuntu 18 LTS

I got a notification that I was using more of the resources than my monthly budget.

On checking with glances - I found something using 90%+ CPU with a link to

I installed ClamAV and ran a scan in the tmp folder and there is an infection. Unfortunately ClamAV can’t remove it.

I tried to manually remove - no luck I tried to chmod 777 - no luck

Any ideas what I can do to clean up the infection? Any ideas how I can figure out how this got into my droplet?

Hello there,

ClamAV scan will usually return a list of files/folders that are infected and you can act based on this information. You can remove any files that are been uploaded/infected when logged in as the root

As mentioned if you’re not familiar with the process you can always reach out to a third party that can help you with the process.

Additionally, if you have a snapshot or backup of your droplet before the infection occurred you can revert the changes by spinning a new droplet from your snapshot or restoring files from a backup.

Hi @smallaquaurchin,

I’m mostly certain there are other areas a part from the TMP folder that got infected. In such cases, it’s always best to contact a security expert to help you clean your Droplet and Website. That is of course if you can’t do it yourself.

Regarding the /tmp folder. You should be able to remove its contents but not the folder itself.
