List of CVEs: CVE-2010-2568

This module searches for the Fanny.bmp worm related reg keys. fannybmp is a worm that exploited zero day vulns (more specifically, the LNK Exploit CVE-2010-2568). Which allowed it to spread even if USB Autorun was turned off. This is the same exploit that was used in StuxNet.

Module Ranking and Traits

Module Ranking:

  • normal: The exploit is otherwise reliable, but depends on a specific version and can't (or doesn't) reliably autodetect. More information about ranking can be found here.

Basic Usage

There are two ways to execute this post module.

From the Meterpreter prompt

The first is by using the "run" command at the Meterpreter prompt. It allows you to run the post module against that specific session:

meterpreter > run post/windows/gather/forensics/fanny_bmp_check

From the msf prompt

The second is by using the "use" command at the msf prompt. You will have to figure out which session ID to set manually. To list all session IDs, you can use the "sessions" command.

msf > use post/windows/gather/forensics/fanny_bmp_check
msf post(fanny_bmp_check) > show options
    ... show and set options ...
msf post(fanny_bmp_check) > set SESSION session-id
msf post(fanny_bmp_check) > exploit

If you wish to run the post against all sessions from framework, here is how:

1 - Create the following resource script:


framework.sessions.each_pair do |sid, session|
  run_single("use post/windows/gather/forensics/fanny_bmp_check")
  run_single("set SESSION #{sid}")
  run_single("run")
end

2 - At the msf prompt, execute the above resource script:

msf > resource path-to-resource-script

Required Options

  • SESSION: The session to run this module on.

Knowledge Base

Vulnerable Application

Fanny or DWE for short. (DWE = DementiaWheel)

Detection module based on the post/windows/gather/forensics/duqu_check module. Fanny is a worm that infects windows machines, via USB (not trough Autorun, or at least not only).

In fact, it used exploits later found in StuxNet. It creates creates some Registry artifacts.

This module is intended to detect those artifacts.

Supported Environments:

  • Windows x86

Supported SessionTypes:

  • Meterpreter
  • Shell

Supported OS's:

  • Windows XP Pro (SP3)

Verification Steps

  • Start msfconsole
  • Open a session on a Windows host (using exploit/windows/smb/ms08_067_netapi for example)
  • Use post/windows/gather/forensics/fanny_bmp_check
  • Set the SESSION datastore option to the target session
  • Run the module
