I'm IT in a small company. The network is about as ancient as most of the staff (at 30, I'm the company's youngest), and the staff also is notorious for spreading viruses around the network despite our best efforts of warning, virus prevention, and education.
And then ground zero finally hits. Our first machine is infected by Cryptolocker. Fortunately, it has no mapped drives, so only the machine was infected. But that leads me to my questions.
Is there a system minimum requirement for this thing to work? Silly as this may sound, we still run Windows 2000 in the network here (Server 2000 is our main DNS server), though most of the network runs XP and Server 2003. I couldn't find any evidence of their being a system minimum but I'm not about to rule anything out quite yet. I just know our linux and IBM boxes are safe.
This article on BleepingComputer has a lot of information about protecting personal computers (and linked network drives), but is there a way to protect the server itself? CryptoPrevent runs great on the client computers, but we'd like to preemptively protect our servers too. I'm not sure if there's a way to prevent server files from being encrypted from am infected client computer, but anything will help at this point.
