Four Iranian cyber actors allegedly conducted computer intrusions targeting U.S. Government agents on behalf of the Islamic Revolutionary Guard Corps (IRGC), using malicious code and fraudulent online identities to gain unauthorized access to protected networks. A federal grand jury in Washington, D.C. indicted Mojtaba Masoumpour, Behzad Mesri, Hossein Parvar, and Mohamad Paryar in February 2019 on charges including conspiracy to commit computer intrusion, aggravated identity theft, and aiding and abetting. The suspects remain at large, and information about their whereabouts or activities could help law enforcement locate them and prevent further cyber threats against U.S. government systems.
