Kaspersky Lab
In May 2012, Kaspersky Lab identified the malware Flame, which a researcher described as potentially "the most sophisticated cyber weapon yet unleashed". According to the researchers in Kaspersky Lab, the malware had infected an estimated 1,000 to 5,000 machines worldwide when asked by the United Nations International Telecommunications Union to investigate reports of a virus affecting Iranian Oil Ministry computers. As Kaspersky Lab investigated, they discovered an MD5 hash and filename that appeared only on customer machines from Middle Eastern nations. After discovering more pieces, researchers dubbed the program "Flame" after the name of one of its modules.
