Beware Of The Mask
Security researchers at Kaspersky Lab have uncovered a sophisticated attack tool that has been in use by a cyberespionage ring since 2007. The Mask toolkit creates malware that can evade detection and is currently believed to be one of the most advanced threats ever discovered. In addition to extremely sophisticated malware, Mac and Linux versions exist.
The Mask, named for the Spanish word "careto" or "mask," which was found in the codebase, has targeted government offices, energy and oil industry companies, research institutions and private equity firms. The number of victims is not known but the extent is believed to be massive, with more than 380 victims in at least 31 countries, including the U.S. The attack spreads via spearphishing email messages. Once a victim's system is infected, the malware steals all data on the system and remains undercover.
