Apparently Flame would be an excellent big data case study domain

"To prevent Flame’s operators or future copycats from spoofing its certificates, Microsoft released an emergency security advisory, and patch, on Monday. But even without the patch, the company noted that the virus was so focused in its scope — it was aimed at computers in the Middle East — that the chance of it spreading on a huge scale was unlikely.
Another reason people need not worry: The virus is no longer spreading. On May 28, the same day researchers announced they had discovered Flame, its command-and-control centers — which had been operating for at least the last four years — went dark."
