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

Process activity

The Trojan creates the following process(es):

%original file name%.exe:1948
%original file name%.exe:1516

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

%original file name%.exe:1664

Mutexes

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

File activity

The process %original file name%.exe:1664 makes changes in the file system.

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

%Documents and Settings%\%current user%\Application Data\explorer (33 bytes)
%Documents and Settings%\%current user%\Application Data\windef.exe (5190 bytes)

Registry activity

The process %original file name%.exe:1664 makes changes in the system registry.

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

[HKLM\SOFTWARE\Microsoft\Cryptography\RNG]
"Seed" = "1F DF CF 1F 3C 5A 5C 5E 84 1F 9A F0 A4 52 BC 3F"

[HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\policies\Explorer\Run]
"Windows Firewall" = "%Documents and Settings%\%current user%\Application Data\windef.exe"

[HKCU\Software\VB and VBA Program Settings\INSTALL\DATE]
"CVX1AG1G6J" = "March 1, 2015"

[HKCU\Software\VB and VBA Program Settings\SrvID\ID]
"CVX1AG1G6J" = "Doc.A"

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

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

[HKCU\Software\Microsoft\Windows\CurrentVersion\Run]
"Windows Firewall" = "%Documents and Settings%\%current user%\Application Data\windef.exe"

[HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run]
"Windows Firewall" = "%Documents and Settings%\%current user%\Application Data\windef.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 Trojan'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:1948
%original file name%.exe:1516
Delete the original Trojan file.
Delete or disinfect the following files created/modified by the Trojan:
%Documents and Settings%\%current user%\Application Data\explorer (33 bytes)
%Documents and Settings%\%current user%\Application Data\windef.exe (5190 bytes)
Delete the following value(s) in the autorun key (How to Work with System Registry):
[HKCU\Software\Microsoft\Windows\CurrentVersion\Run]
"Windows Firewall" = "%Documents and Settings%\%current user%\Application Data\windef.exe"

[HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run]
"Windows Firewall" = "%Documents and Settings%\%current user%\Application Data\windef.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.
