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 Worm's file once a user opens a drive's folder in Windows Explorer.

Process activity

The Worm creates the following process(es):

%original file name%.exe:268

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

%original file name%.exe:660

Mutexes

The following mutexes were created/opened:

ShimCacheMutex9ILHKJHXZ4

File activity

The process %original file name%.exe:268 makes changes in the file system.

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

%Documents and Settings%\%current user%\Application DataMicrosoft\System\Services\18.exe (1425 bytes)

The process %original file name%.exe:660 makes changes in the file system.

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

%Documents and Settings%\%current user%\Application Data\svchost.exe (401 bytes)
%Documents and Settings%\%current user%\Application Data\logs (33 bytes)

Registry activity

The process %original file name%.exe:268 makes changes in the system registry.

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

[HKLM\SOFTWARE\Microsoft\Cryptography\RNG]
"Seed" = "EF EE 03 C4 D4 91 9E EC C1 AA 6F FC ED 4F 78 62"

[HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders]
"AppData" = "%Documents and Settings%\%current user%\Application Data"

"Cache" = "%Documents and Settings%\%current user%\Local Settings\Temporary Internet Files"

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

[HKCU\Software\Microsoft\Windows\CurrentVersion\Run]
"18.exe" = "%Documents and Settings%\%current user%\Application DataMicrosoft\System\Services\18.exe"

[HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run]
"18.exe" = "%Documents and Settings%\%current user%\Application DataMicrosoft\System\Services\18.exe"

The process %original file name%.exe:660 makes changes in the system registry.

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

[HKLM\SOFTWARE\Microsoft\Cryptography\RNG]
"Seed" = "51 37 C0 C4 CE E5 2E 54 77 7A 5B E3 7A BD CA 49"

[HKCU\Software\VB and VBA Program Settings\SrvID\ID]
"9ILHKJHXZ4" = "Slaves"

[HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders]
"AppData" = "%Documents and Settings%\%current user%\Application Data"

[HKCU\Software\VB and VBA Program Settings\INSTALL\DATE]
"9ILHKJHXZ4" = "September 11, 2014"

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 Worm'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:268
Delete the original Worm file.
Delete or disinfect the following files created/modified by the Worm:
%Documents and Settings%\%current user%\Application DataMicrosoft\System\Services\18.exe (1425 bytes)
%Documents and Settings%\%current user%\Application Data\svchost.exe (401 bytes)
%Documents and Settings%\%current user%\Application Data\logs (33 bytes)
Delete the following value(s) in the autorun key (How to Work with System Registry):
[HKCU\Software\Microsoft\Windows\CurrentVersion\Run]
"18.exe" = "%Documents and Settings%\%current user%\Application DataMicrosoft\System\Services\18.exe"

[HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run]
"18.exe" = "%Documents and Settings%\%current user%\Application DataMicrosoft\System\Services\18.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.
