The operation identified international cyber crime rings that are linked to multiple variants of the Yahos malicious software, or malware, which is linked to more than 11 million compromised computer systems and over $850 million in losses via the Butterfly Botnet, which steals computer users’ credit card, bank account, and other personal identifiable information.
Facebook’s security team provided assistance to law enforcement throughout the investigation by helping to identify the root cause, the perpetrators, and those affected by the malware. Yahos targeted Facebook users from 2010 to October 2012, and security systems were able to detect affected accounts and provide tools to remove these threats.
The FBI received invaluable cooperation, assistance, and response from international law enforcement partners in the aforementioned countries.
