"The unknown authors of Flame shut down the sprawling command-and-control (C&C) infrastructure immediately after last Monday's disclosure that the highly sophisticated malware had remained undetected for at least two years on computers belonging to government-run organizations, private companies, and others."
"Over the past four years, the Flame C&C infrastructure relied on at least 22 separate IP addresses. Servers that ran the channels appeared to be running the Ubuntu Linux distribution. "
Now, are we supposed to be proud or disturbed about the fact that the creators of this virus favours Ubuntu over distros like CentOS or Red Hat?
(Of course it could have been any distro on those servers.)
P.S Don't worry! This isn't about Flame "infecting" Ubuntu machines. What were talking about here is that those who made this virus used a network of Ubuntu servers in order to handle the data that the virus stole from the infected machines.
