Flame, also known as Flamer, sKyWIper, and Skywiper, is modular computer malware discovered in 2012 that attacks computers running the Microsoft Windows operating system.The program is being used for targeted cyber espionage in Middle Eastern countries. Its discovery was announced on 28 May 2012 by MAHER Center of Iranian National Computer Emergency Response Team (CERT),Kaspersky Lab and CrySyS Lab of the Budapest University of Technology and Economics. The last of these stated in its report that "sKyWIper is certainly the most sophisticated malware we encountered during our practice; arguably, it is the most complex malware ever found."Flame can spread to other systems over a local network (LAN) or via USB stick. It can record audio, screenshots, keyboard activity and network traffic. The program also records Skype conversations and can turn infected computers into Bluetooth beacons which attempt to download contact information from nearby Bluetooth-enabled devices. This data, along with locally stored documents, is sent on to one of several command and control servers that are scattered around the world. The program then awaits further instructions from these servers.
According to estimates by Kaspersky in May 2012, Flame had initially infected approximately 1,000 machines, with victims including governmental organizations, educational institutions and private individuals. At that time 65% of the infections happened in Iran, Israel, Sudan, Syria, Lebanon, Saudi Arabia, and Egypt, with a "huge majority of targets" within Iran. Flame has also been reported in Europe and North America. Flame supports a "kill" command which wipes all traces of the malware from the computer. The initial infections of Flame stopped operating after its public exposure, and the "kill" command was sent.Flame is an uncharacteristically large program for malware at 20 megabytes. It is written partly in the Lua scripting language with compiled C++ code linked in .
