Help identifying virus (bricking PCs on network join)

Recently our network has suffered a breach. We don’t know what happened, but something came in and now, whenever any device connects to the network it crashes, wipes itself, or fully bricks entirety. This has happened with a multitude of different devices and OSs (including windows, windows server, and ubuntu).

Anyone know what this could be?

Crashes can be analyzed. Make sure you’re set up for full memory dumps in Windows. Also, install Sysmon with the -n option to capture network traffic and file operation events. What do you mean ‘when it connects to the network’? Are you joining a domain, or just plugging into the same LAN, or what?
