However, the Symantec researchers don't know what these modules do yet. "We currently do not have copies of these modules and hence we are looking for them so we can analyze them in greater detail," Katsuki said.
The number of computers infected by Crisis/Morcut is not very high at the moment. Kaspersky Lab has identified a total of 21 victims located in Italy, Mexico, Iran, Turkey, Iraq, Oman, Brazil, Kazakhstan, Kyrgyzstan and Tajikistan, Golovanov said. "This may not account for all the victims as other vendors may have detections on their systems too."
Security researchers from Intego previously said that sections of code from Crisis suggest a connection with a commercial Trojan program developed by an Italian company called HackingTeam and licensed to law enforcement and intelligence agencies for surveillance purposes.
The low number of infections and their wide geographic distribution could suggest that this malware is used in targeted attacks rather than widespread ones.
