My CNC Machine was Hacked!

When I walked into my garage, my lathe had Mozilla Firefox open and the mouse was moving across the screen! Hundreds of terminal windows were open and hundreds of application launchers were open. The hacker opened capital one banking online. I was shocked! I wanted my dad to see this so I shouted for him to look, but the hacker clearly understood what I said and therefore stopped what he was doing. I will remove the wifi card from the computer, and only periodically connect with a USB wifi adapter from here on out. Fortunately I have no sensitive information stored on this Linux install, but this is extremely concerning. What can I do to find out what this hacker accessed? I will include a few cellphone photos of what the hacker connected to, but I feel like there must be more that I'm not seeing.

Its always a worry this stuff.
I would be far more concerned about firewall security. How did he get in? What other PCs is he using on your network?

can you post some info of what Linux flavour you were running (Debian/whatever) and what version it was

hence was it kept up to date with security fixes etc?

I presume that it would have been a Firefox breach, something like or via this.

important to keep up to date on security patches.

I don't think it will be a linuxcnc issue.

I'm certainly not up to date, I did the regular 2.8 LinuxCNC install that way I could use the probe basic GUI. I saved my configuration and I'm going to start over with a fresh install. I think I will use 2.9 and certainly remove the wifi card. This machine doesn't really need internet access and I can't risk hackers getting into other computers in the house.

As Rod said I would be far more concerned about how they got past the firewall on your router. Of all of my PCs the CNC would be the least of my worries.
