This malware is named "Flame" by the founder of Kaspersky Lab, this Flame itself has a spy function in the form of data theft in various ways and methods of controlled deployment. Flame is an attack toolkit that combines the backdoor, trojan, and worm properties so that it can copy itself over the network and external media if ordered by the manufacturer. Once inside the computer, this malware can run a series of spying and data theft activities, including recording keyboard keystrokes, recording user conversations via microphone, and taking screenshots when certain applications are run, such as instant messenger and Outlook. The way Flame infects computers is still unknown exactly, which is definitely through the security hole in the operating system.
That's the info on the 15 Most Dangerous Computer Viruses Throughout History that has stirred global panic.
