On February 8, 2019, a federal grand jury in Washington, D.C. indicted four Iranian cyber actors—Mojtaba Masoumpour, Behzad Mesri, Hossein Parvar, and Mohamad Paryar—for their alleged involvement in computer intrusions targeting U.S. Government agents. The conspirators, operating at the behest of the Islamic Revolutionary Guard Corps (IRGC), used malicious code, fake online personas, and stolen personal information to gain unauthorized access to protected computer networks. The case remains active as the suspects remain at large and continue to pose a significant cybersecurity threat to U.S. government systems and personnel.
