An anonymous reader quotes a report from NPR: The U.S. Department of Justice has indicted seven Iranians with intelligence links over a series of crippling cyberattacks against 46 U.S. financial institutions between 2011 and 2013. The indictment, which was unsealed Thursday, also accuses one of the Iranians of remotely accessing the control system of a small dam in Rye, N.Y, during the same period. Attorney General Loretta Lynch said the indictment is meant to send a message: "That we will not allow any individual, group, or nation to sabotage American financial institutions or undermine the integrity of fair competition in the operation of the free market." According to the indictment, the seven men worked for two Iran-based computer security companies that have done work for the Iranian government, including the powerful Islamic Revolutionary Guard Corps. The men allegedly carried out large-scale distributed denial of service (DDoS) attacks, which overwhelm a server with communications in order to disable it.
