Dynamic Analysis

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:944

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

iexplore.exe:660

Mutexes

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

File activity

The process %original file name%.exe:944 makes changes in the file system.

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

%WinDir%\install\SVCHOST.exe (1425 bytes)
%Documents and Settings%\%current user%\Local Settings\Temp\XX--XX--XX.txt (235 bytes)

Registry activity

The process %original file name%.exe:944 makes changes in the system registry.

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

[HKLM\SOFTWARE\Microsoft\Cryptography\RNG]
"Seed" = "AF 01 5A 03 95 1F BC 84 9A B6 3E CB 7A 87 0E 11"

[HKLM\SOFTWARE\Microsoft\Active Setup\Installed Components\{886271DY-283N-Q34Q-T67N-B7AIG38JMW3F}]
"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"

Dropped PE files

There are no dropped PE files.

HOSTS file anomalies

No changes have been detected.

Rootkit activity

No anomalies have been detected.

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:944
Delete the original Generic file.
Delete or disinfect the following files created/modified by the Generic:
%WinDir%\install\SVCHOST.exe (1425 bytes)
%Documents and Settings%\%current user%\Local Settings\Temp\XX--XX--XX.txt (235 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"
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.
