Microsoft, FBI And Others Join Forces to Combat Cybercrime Ring
Microsoft works with financial services industry leaders, other industry partners, and law enforcement to disrupt a global cybercrime operation responsible for over half a billion dollars (USD) in financial fraud.
In a coordinated operation, Microsoft in cooperation with the Financial Services - Information Sharing and Analysis Center (FS-ISAC), NACHA - The Electronic Payments Association, the American Bankers Association (ABA) - Agari, and other companies, as well as the Federal Bureau of Investigation, has disrupted more than a thousand botnets that are responsible for stealing people's online banking information and personal identities. The FBI took coordinated separate steps related to the operation. Botnets are networks of compromised computers infected by malicious software to be controlled by cybercriminals known as botherders.
This coordinated disruption resulted from an investigation that Microsoft and its financial services and technology industry partners began in early 2012. After looking into this threat, Microsoft and its partners discovered that once a computer was infected with Citadel malware, that malware began monitoring and recording a victim?s keystrokes. This tactic, known as keylogging, provides cybercriminals information to gain direct access to a victim?s bank account or any other online account in order to withdraw money or steal personal identities. This means that when victims are using their computers to access their bank or online accounts, cybercriminals can use the stolen information to quietly pilfer those same accounts as well. Microsoft also found that in addition to being responsible for more than half a billion dollars (USD) in losses among people and businesses worldwide, the Citadel malware has affected upwards of five million people, with some of the highest number of infections appearing in the U.S., Europe, Hong Kong, Singapore, India, and Australia. Citadel is a global threat that is believed may have already infected victims in more than ninety countries worldwide since its inception.
Last week Microsoft filed a civil suit against the cybercriminals operating the Citadel botnets, receiving authorization from the U.S. District Court for the Western District of North Carolina for Microsoft to simultaneously cut off communication between 1,462 Citadel botnets and the millions of infected computers under their control. On June 5, Microsoft, escorted by the U.S. Marshals, seized data and evidence from the botnets, including computer servers from two data hosting facilities in New Jersey and Pennsylvania. Microsoft also provided information about the botnets' operations to international Computer Emergency Response Teams (CERTs), so these partners could take action at their discretion on additional command and control infrastructure for the botnets located outside of the U.S.
The FBI also provided information to foreign law enforcement counterparts so that they could also take voluntary action on botnet infrastructure located outside of the U.S. The FBI also obtained and served court-authorized search warrants domestically related to the botnets.
Due to the size and complexity of the threat, Microsoft and its partners do not expect to fully eliminate all of the botnets using Citadel. However, it is expected that this action will significantly disrupt the botnets? operation, making it riskier and more expensive for the cybercriminals to continue doing business and allowing victims to free their computers from the malware.
Immediately following the disruption, Microsoft will use the threat intelligence gathered during the seizure to work with Internet Service Providers and Computer Emergency Response Teams worldwide to notify people if their computer is infected. Microsoft will be making this information available through its Cyber Threat Intelligence Program (C-TIP), including the recently-announced cloud-based version of the program.
