AnubisNetworks, a leader in real-time threat intelligence helps FBI in U.S.-Led Multi-National Action against “GameOver Zeus” Botnet and “Cryptolocker” Ransomware.



According to security researchers, it’s estimated that Cryptolocker has infected more than 234,000 computers, generating losses of more than $27 million in ransom payments made in just the first two months since the ransomware emerged. In addition, the FBI estimates that GameOver Zeus is responsible for infecting between 500,000 and 1 million computers worldwide resulting in more than $100 million in losses.

In a recent press statement released by the US Department of Justice, Deputy Attorney General Cole stated “this operation disrupted a global botnet that had stolen millions from businesses and consumers as well as a complex ransomware scheme that secretly encrypted hard drives and then demanded payments for giving users access to their own files and data,” Cole noted that “We succeeded in disabling GameOver Zeus and Cryptolocker only because we blended innovative legal and technical tactics with traditional law enforcement tools and developed strong working relationships with private industry experts and law enforcement counterparts in more than 10 countries around the world.” [1]

AnubisNetworks CEO, Francisco Fonseca commented, “It was a privilege to assist in this operation and have the opportunity to collaborate and share the intelligence generated by Cyberfeed, AnubisNetworks threat intelligence solution.” Francisco added “we were able to successfully sinkhole this botnet and have been following its activity for some time now”.

The service monitors the surrounding ecosystem, detects botnet activity, analyzes and qualifies the risk and finally delivers context and a holistic view of the cyber-threat, providing companies and governments with actionable intelligence to fight back!
