I remember reading about malware like this some time back. I tried everything I could to prepare but got vetoed at every turn by management. My idea was to do "pull" backups to a server, instead of "push" backups to shares, instead my boss's boss bought some commercial backup package that while ok, when it bombed a t-log chain, they blamed microsoft's implementation of native sql server backups, and of course was nowhere near my dream "pull" server thing, heck, I don't know if my idea was even valid, I'm not that smart a guy honestly, you gotta know your limits.
I wanted flash removed from my desktop, because being the intellectual slug I am, I google everything, like how to get the correct date and time. My previous job was as a convenience store clerk, and as I'm in the process of getting fired right this very week, I suspect it'll be my next job too. I was told by my boss's boss and his cousin the gaming guy who built servers that "our firewall blocks everything".
Of course, I got a text message one morning from my boss, while I don't remember the exact text, I remember it included the word "armagghedon". I came in to work carrying my uninfected laptop, and heck, my pc looked pretty normal except the icons had changed and sort of "doubled up", each second version contained the same message, you know the drill.
I'm an sql guy, I know I'm not all CS smart like everyone here but I gotta say it was obvious even to me what was coming, its like an enemy doing bombing raids in the next city over and people are still out there watering their lawns like nothing is happening. Friggin malware, I guess it pays well tho.
