Payload

Behaviour	Description
WormAutorun	A worm can spread via removable drives. It writes its executable and creates "autorun.inf" scripts on all removable drives. The autorun script will execute the Generic's file once a user opens a drive's folder in Windows Explorer.

Process activity

The Generic creates the following process(es):

%original file name%.exe:680

The Generic injects its code into the following process(es):

rundll32.exe:420
Explorer.EXE:1912

Mutexes

The following mutexes were created/opened:No objects were found.

File activity

The process %original file name%.exe:680 makes changes in the file system.

The Generic creates and/or writes to the following file(s):

%WinDir%\install\SVCHOST.exe (2321 bytes)
%Documents and Settings%\%current user%\Local Settings\Temp\XX--XX--XX.txt (263 bytes)

Registry activity

The process %original file name%.exe:680 makes changes in the system registry.

The Generic creates and/or sets the following values in system registry:

[HKLM\SOFTWARE\Microsoft\Cryptography\RNG]
"Seed" = "71 BE 00 51 E7 9B 91 63 5E 89 A7 9F FB 87 98 04"

[HKLM\SOFTWARE\Microsoft\Active Setup\Installed Components\{M200SW8G-057E-O720-Y45F-GKYWP0450A22}]
"StubPath" = "%WinDir%\install\SVCHOST.exe Restart"

[HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer\Run]
"Policies" = "%WinDir%\install\SVCHOST.exe"

[HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\policies\Explorer\Run]
"Policies" = "%WinDir%\install\SVCHOST.exe"

To automatically run itself each time Windows is booted, the Generic adds the following link to its file to the system registry autorun key:

[HKCU\Software\Microsoft\Windows\CurrentVersion\Run]
"HKCU" = "%WinDir%\install\SVCHOST.exe"

[HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run]
"HKLM" = "%WinDir%\install\SVCHOST.exe"

The process rundll32.exe:420 makes changes in the system registry.

The Generic creates and/or sets the following values in system registry:

[HKLM\SOFTWARE\Microsoft\Cryptography\RNG]
"Seed" = "29 68 20 CC 2B 97 C7 F3 98 04 4D 92 57 F1 80 CD"

[HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\MountPoints2\{c155cd73-744b-11e2-8294-806d6172696f}]
"BaseClass" = "Drive"

[HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\MountPoints2\{c155cd72-744b-11e2-8294-806d6172696f}]
"BaseClass" = "Drive"

[HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\MountPoints2\{b98117e8-75ca-11e2-81b2-000c293708fb}]
"BaseClass" = "Drive"

[HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\MountPoints2\{c155cd75-744b-11e2-8294-806d6172696f}]
"BaseClass" = "Drive"

Propagation

A worm can spread via removable drives. It writes its executable and creates "autorun.inf" scripts on all removable drives. The autorun script will execute the Generic's file once a user opens a drive's folder in Windows Explorer.

Removals

Remove it with Ad-Aware

Click (here) to download and install Ad-Aware Free Antivirus.
Update the definition files.
Run a full scan of your computer.

Manual removal*

Terminate malicious process(es) (How to End a Process With the Task Manager):
%original file name%.exe:680
Delete the original Generic file.
Delete or disinfect the following files created/modified by the Generic:
%WinDir%\install\SVCHOST.exe (2321 bytes)
%Documents and Settings%\%current user%\Local Settings\Temp\XX--XX--XX.txt (263 bytes)
Delete the following value(s) in the autorun key (How to Work with System Registry):
[HKCU\Software\Microsoft\Windows\CurrentVersion\Run]
"HKCU" = "%WinDir%\install\SVCHOST.exe"

[HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run]
"HKLM" = "%WinDir%\install\SVCHOST.exe"
Clean the Temporary Internet Files folder, which may contain infected files (How to clean Temporary Internet Files folder).
Find and delete all copies of the worm's file together with "autorun.inf" scripts on removable drives.
Reboot the computer.

*Manual removal may cause unexpected system behaviour and should be performed at your own risk.
