We had an employee who visited an AUTO PARTS SITE that was hacked and infected. It downloaded a backdoor trojan, which allowed installer downloads. In minutes, his machine was swamped with popups, toolbars, fake spyware scanners like Spylocked, and then everything propagated on the network shares. Some of these defeated firewall settings and shut down AV's.
Some of the CNC machine tools were Windows Based (Are they NUTS??).
The machines were running expensive, intricate titanium parts when they went down.
We lost $50,000.
The people who write and distribute many of these are known. Nothing happens to them.
I imagine that there were a lot of unhappy travellers that day. I tried calling the tech support # on the hotel's website and couldn't get through.
.....that needs to end.....
.....by one means or another.....
