he Justice Department today announced the completion of a court-authorized operation, code-named MEDUSA, to disrupt a global peer-to-peer network of computers compromised by sophisticated malware, called “Snake”, that the U.S. Government attributes to a unit within Center 16 of the Federal Security Service of the Russian Federation (FSB). For nearly 20 years, this unit, referred to in court documents as “Turla,” has used versions of the Snake malware to steal sensitive documents from hundreds of computer systems in at least 50 countries, which have belonged to North Atlantic Treaty Organization (NATO) member governments, journalists and other targets of interest to the Russian Federation.
