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:444

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

vbc.exe:1724

Mutexes

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

File activity

The process %original file name%.exe:444 makes changes in the file system.

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

%Documents and Settings%\%current user%\Local Settings\Temp\vbc.exe (7547 bytes)
%Documents and Settings%\%current user%\Application Data\WinUpdtr\%original file name%.exe (4185 bytes)

The process vbc.exe:1724 makes changes in the file system.

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

%Documents and Settings%\%current user%\Application Data\F1 (32 bytes)
%Documents and Settings%\%current user%\Application Data\TTDE11QSGU.exe (3860 bytes)

Registry activity

The process %original file name%.exe:444 makes changes in the system registry.

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

[HKLM\SOFTWARE\Microsoft\Cryptography\RNG]
"Seed" = "35 44 BB 7F 0E BE E6 BD BF 53 27 F4 85 A9 33 16"

[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 Trojan adds the following link to its file to the system registry autorun key:

[HKCU\Software\Microsoft\Windows\CurrentVersion\Run]
"WinUpdtr" = "%Documents and Settings%\%current user%\Application Data\WinUpdtr\%original file name%.exe"

The process vbc.exe:1724 makes changes in the system registry.

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

[HKLM\SOFTWARE\Microsoft\Cryptography\RNG]
"Seed" = "B7 8E EA C4 99 5B 44 0D A9 5F 4C 3C B8 61 8C 3B"

[HKCU\Software\VB and VBA Program Settings\INSTALL\DATE]
"MANGHGWH0R" = "August 8, 2014"

[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]
"MANGHGWH0R" = "Update1"
