Just thought I'd share a little experience I had yesterday regarding a Crypto Miner I discovered inside my Node-Red. I have Node-Red in a Docker Container and noticed my server CPU usage spiked to nearly 100% full-time. Upon researching the cause, I saw the responsible process was /var/tmp/sustes -…

How did you get 'infected', was it a rogue flow/node?

Just to add a key missing piece of information here .. this was a node-red instance exposed on the internet with no security applied. This is why we always go to great lengths to highlight the security implications of exposing NR to the internet. The exec node gives whoever can deploy a flow comple…

Here is the added information. I did in fact have Node-Red under a Reverse Proxy (NGINX) with BasicAuth user/password.

I'm on a Hetzner physical server......That Digital Ocean post was just something I found on the internet to help me diagnose and treat my problem. I am not using anything from Digital Ocean.
