About 12:20PM today, all of our Enterprise Level HP Printers went down with Security Error 33.05.13. They have not recovered.
I've researched that error and here's the troubleshooting so far:
Tried firmware reload via USB drive. Boots to same error
Booting printers disconnected from network results in a complete boot. If I plug them back in, they lock up and if you reboot while connected, same security alert.
This is only affecting Enterprise Level Printers and not standard laserjet and deskjets. I assume it is due to added security in those class of printers.
And as I type this, our Toshiba Copiers are very sluggish when using the on device buttons. The software on them is very slow.
My PC lost internet only around 12:20PM and I did a release/renew and about that time, the HP's when down. I don't think this is the cause but it is interesting.
No other adverse effects on workstations or servers.
I've worked with a local HP rep who came here and HP on the phone and they don't know what the cause is.
I am about to head to an even for a few hours but will be back here at 7PM central time to continue to troubleshoot. The first thing I may do is reboot all my servers, which includes Domain Controller, DHCP and DNS.
But I am worried we have had some kind of attack and with the focus on cyber-security, management wants to be reassured.
I have WireShark but I admit I am not good at reading the results.
I'll update more in a few hours.
