Summary:

Trojan. A program that appears to do one thing but actually does another (a.k.a. Trojan Horse).

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:704
%original file name%.exe:1236

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

%original file name%.exe:1140
Explorer.EXE:532

Mutexes

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

File activity

The process %original file name%.exe:1140 makes changes in the file system.
The Trojan creates and/or writes to the following file(s):

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

Registry activity

The process %original file name%.exe:704 makes changes in the system registry.
The Trojan creates and/or sets the following values in system registry:

[HKLM\SOFTWARE\Microsoft\Cryptography\RNG]
"Seed" = "6E 3A 34 0A 0E 25 D3 C1 FB C7 D9 7D EC 7C E0 BB"

The process %original file name%.exe:1140 makes changes in the system registry.
The Trojan creates and/or sets the following values in system registry:

[HKLM\SOFTWARE\Microsoft\Cryptography\RNG]
"Seed" = "82 02 E5 B2 5B 0E DB 63 8F 90 85 38 68 21 9D A1"

[HKLM\SOFTWARE\Microsoft\Active Setup\Installed Components\{8C6A2FDA-E69E-CF1D-F0EF-EE4E1DC12A57}]
"StubPath" = "%Documents and Settings%\%current user%\Application Data\svchost.exe"

[HKCU\Software\Microsoft\Active Setup\Installed Components\{8C6A2FDA-E69E-CF1D-F0EF-EE4E1DC12A57}]
"StubPath" = "%Documents and Settings%\%current user%\Application Data\svchost.exe"

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

[HKCU\Software\VB and VBA Program Settings\SrvID\ID]
"7F0Z67CW59" = "-*\\||//*-"

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

[HKCU\Software\VB and VBA Program Settings\INSTALL\DATE]
"7F0Z67CW59" = "June 2, 2016"

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]
"WinDefender" = "%Documents and Settings%\%current user%\Application Data\svchost.exe"

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