‘Darkode’ goes dark

shroud-horizonThe Pittsburgh Post-Gazette explains how the investigation started:

“Following a lead generated in Pittsburgh around 18 months ago, the FBI cybersquad here launched Operation Shrouded Horizon. The bureau’s local office assembled a coalition that started domestically with the bureau’s offices in Washington, D.C., San Diego, New Orleans and San Francisco, and extended to online enforcement teams in 20 countries, including numerous European countries, Israel, Australia, Colombia, Brazil and Nigeria.”

The FBI worked with law enforcement agencies in 20 countries to investigate, search and arrest some 70 members and associates of Darkode around the world, as part of the multi-national ‘Operation Shrouded Horizon.’ According to the DOJ, it was the largest coordinated international law enforcement effort ever directed at a cyber-criminal forum.

“This is a milestone in our efforts to shut down criminals’ ability to buy, sell, and trade malware, botnets and personally identifiable information used to steal from U.S. citizens and individuals around the world,” FBI Deputy Director Mark Giuliano said. “Cyber criminals should not have a safe haven to shop for the tools of their trade and Operation Shrouded Horizon shows we will do all we can to disrupt their unlawful activities.”

U.S. Federal officials say the investigation into Darkode is continuing.
