Following the naming of the alleged operators of the Koobface botnet earlier this week, the botnet has apparently been shut down.

"The command-and-control server used to run the Koobface botnet, known as the Mothership, is now offline and new infections seem to have dropped off, experts say," writes Threatpost's Dennis Fisher.

"A Facebook security official told Reuters that the C&C server used by the Koobface gang is now offline, and researchers say that the gang also has essentially dropped offline in the last couple of days," Fisher writes. "This has made life much more difficult for the officials and researchers who have been tracking the crew."
