GameOver Zeus botnet disrupted by FBI, Microsoft and multi-national agencies

GameOver_Zeus_Scope(LiveHacking.Com) – A multi-national team of security experts and law enforcement agencies including the U.S. Department of Justice, the FBI, Europol, and the UK’s National Cyber Crime Unit have successfully disrupted  the GameOver Zeus botnet. The malware, which is a peer-to-peer (P2P) variant of the Zeus family of bank credential-stealing trojan, is thought to be responsible for the theft of millions of dollars from businesses and consumers all around the world.

Also known as P2P Zeus or GO Zeus, the malware uses a decentralized network system of compromised PCs and web servers to execute command-and-control. Its peer-to-peer nature meant that command instructions could come from any of the infected computers, and made the take down of the botnet more difficult.

The FBI took down portions of the command-and-control infrastructure by seizing domain names used by the malware. Microsoft helped the FBI by providing an analysis of the P2P network and by developing a cleaning solution. According to Richard Domingues Boscovich, Assistant General Counsel, Microsoft Digital Crimes Unit, “Based upon these actions, it is anticipated that the cybercriminals’ business model will be disrupted, and they will be forced to rebuild their criminal infrastructure. More importantly, victims of GameOver Zeus have been, and will continue to be, notified and their infected computers cleaned to prevent future harm.”

GameOver Zeus is primarily used by cybercriminals to harvest banking information including login credentials. Once a PC is infected it can be used by the cybercriminals to engage in other malicious activities, such as sending spam or participating in distributed denial-of-service (DDoS) attacks. The malware has also been linked to the CryptoLocker ransomware that restricts access to infected computers and demands the victim provide a payment to the attackers in order to decrypt and recover their files.

Andy Archibald, a Deputy Director at the UK’s National Crime Agency (NCA), said: “Nobody wants their personal financial details, business information or photographs of loved ones to be stolen or held to ransom by criminals. By making use of this two-week window, huge numbers of people in the UK can stop that from happening to them.” Mr Archibald continues: “Those committing cybercrime impacting the UK are often highly-skilled and operating from abroad. The NCA and its partners are alive to the threat, and pursuing new and collaborative ways to tackle and disrupt the perpetrators.”

At the same time as the botnet was being disrupted  a federal grand jury in Pittsburgh unsealed a 14-count indictment against the GameOver Zeus ringleader. Evgeniy Mikhailovich Bogachev, of Anapa, Russian Federation, is charged with with conspiracy, computer hacking, wire fraud,  bank fraud and money laundering. In a separate civil injunction, Bogachev was identified as the ringleader of the gang responsible for the development and operation of the Cryptolocker scheme.
