miniFlame, also known as SPE, was found by Kaspersky Lab's experts in July 2012, and
was originally identified as a Flame module. However, in September 2012, Kaspersky Lab's
research team conducted an in-depth analysis
[http://www.securelist.com/en/blog/750/Full_Analysis_of_Flame_s_Command_Control_servers ]
of Flame's command & control servers (C&C) and found that the miniFlame module was
actually an interoperable tool that could be used as an independent malicious program, or
concurrently as a plug-in for both the Flame and Gauss malware.
- miniFlame, also known as SPE, is based on the same architectural platform
as Flame. It can function as its own independent cyber espionage program or as a
component inside both Flame and Gauss.
- The cyber espionage tool operates as a backdoor designed for data theft and
direct access to infected systems.
- Development of miniFlame might have started as early as 2007 and continued
until the end of 2011. Many variations are presumed to be created. To date, Kaspersky
Lab has identified six of these variants, covering two major generations: 4.x and 5.x.
- Unlike Flame or Gauss, which had high number of infections, the amount of
infections for miniFlame is much smaller. According to Kaspersky Lab's data, the
number of infections is between 10-20 machines. The total number of infections
worldwide is estimated at 50-60.
- The number of infections combined with miniFlame's info-stealing features and
flexible design indicate it was used for extremely targeted cyber-espionage
operations, and was most likely deployed inside machines that were already infected by
Flame or Gauss.
Discovery
The discovery of miniFlame occurred during the in-depth analysis of the Flame and
Gauss malware. In July 2012 Kaspersky Lab's experts identified an additional module of
Gauss, codenamed "John" and found references to the same module in Flame's configuration
files. The subsequent analysis of Flame's command and control servers
[http://www.securelist.com/en/blog/750/Full_Analysis_of_Flame_s_Command_Control_servers ],
conducted in September 2012, helped to reveal that the newly discovered module was in fact
a separate malicious program, although it can be used as a 'plug-in' by both Gauss and
Flame. miniFlame was codenamed SPE in the code of Flame's original C&C servers.
Kaspersky Lab discovered six different variations of miniFlame, all dating back to
2010-2011. At the same time, the analysis of miniFlame points to an even earlier date when
development of the malware was commenced - not later than 2007. miniFlame's ability to be
used as a plug-in by either Flame or Gauss clearly connects the collaboration between the
development teams of both Flame and Gauss. Since the connection between Flame and
Stuxnet/Duqu has already been revealed, it can be concluded that all these advanced
threats come from the same "cyber warfare" factory.
Functionality
The original infection vector of miniFlame is yet to be determined. Given the
confirmed relationship between miniFlame, Flame, and Gauss, miniFlame may be installed on
machines already infected by Flame or Gauss. Once installed, miniFlame operates as a
backdoor and enables the malware operators to obtain any file from an infected machine.
Additional info-stealing capabilities include making screenshots of an infected computer
while it's running a specific program or application in such as a web browser, Microsoft
Office program, Adobe Reader, instant messenger service, or an FTP client. miniFlame
uploads the stolen data by connecting to its C&C server (which may be unique, or 'shared'
with Flame's C&Cs). Separately, at the request from miniFlame's C&C operator, an
additional data-stealing module can be sent to an infected system, which infects USB
drives and uses them to store data that's collected from infected machines without an
internet connection.
Alexander Gostev, Chief Security Expert, Kaspersky Lab, commented: "miniFlame is a
high precision attack tool. Most likely it is a targeted cyberweapon used in what can be
defined as the second wave of a cyberattack. First, Flame or Gauss are used to infect as
many victims as possible to collect large quantities of information. After data is
collected and reviewed, a potentially interesting victim is defined and identified, and
miniFlame is installed in order to conduct more in-depth surveillance and cyber-espionage.
The discovery of miniFlame also gives us additional evidence of the cooperation between
the creators of the most notable malicious programs used for cyber warfare operations:
Stuxnet, Duqu, Flame and Gauss."
Kaspersky Lab would like to thank CERT-Bund/BSI for their kind assistance with this
investigation.
