The Department of Justice on Wednesday indicted two Iranians it says were behind a set of ransomware attacks called "SamSam" that devastated the City of Atlanta in March 2018, as well as the Hollywood Presbyterian Hospital in February 2016 and other victims.

Ransomware is malicious software that locks up computers and any computer-controlled equipment until the victim pays a ransom to the criminal involved. While it's often seen as a purely criminal activity, deployed to get money from unsuspecting businesses, its deployment can cause chaos and nation-state intrigue, as well as major shut-downs in government or corporate services. According to the Department of Justice, of the hundreds of U.S. victims of this campaign, many sustained "substantial losses."
