Version Summary:

Flame is an attack toolkit that allows an attacker to access sensitive information on a targeted system.

 

Description
 

Flame is a sophisticated attack toolkit that allows backdoor access to a targeted system, which could allow an attacker to access sensitive information.  The malicious software also has worm-like features that could allow replication of itself in a local network as well as on removable media.

Flame consists of a package of modules that are almost 20 MB in size when fully deployed, with the ability for an attacker to load additional modules.  It has been reported that some of these modules could be used to sniff network traffic, take screenshots, record audio conversations, or intercept keyboard input on targeted systems.  Additionally, Flame appears to have two modules that are designed for infecting USB sticks, called Autorun Infector and Euphoria.

Flame replicates its way through a local network using a print spooler vulnerability (MS10-061) or remote job tasks.  It can also replicate if it is if executed by a user who has administrative rights to the domain controller.

Although there does not seem to be a specific pattern for Flame attacks, reports have indicated that states in the Middle East, including Iran, Israel/Palestine, Sudan, Syria, Lebanon, Saudi Arabia, and Egypt have the most affected systems.  Infection rates are still low, with under a thousand systems reported as infected with this trojan.

Administrators are advised to allow only trusted users to access local systems.
