Summary:

Worm. A program that is primarily replicating on networks or removable drives.

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:908

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

%original file name%.exe:1244

Mutexes

The following mutexes were created/opened:

ShimCacheMutex
S2UR40XGHV

File activity

The process %original file name%.exe:1244 makes changes in the file system.
The Worm creates and/or writes to the following file(s):

%Documents and Settings%\%current user%\Application Data\Nvidia Physics Drivers Signed\aticlexx.exe (665 bytes)

Registry activity

The process %original file name%.exe:908 makes changes in the system registry.
The Worm creates and/or sets the following values in system registry:

[HKLM\SOFTWARE\Microsoft\Cryptography\RNG]
"Seed" = "F8 40 76 6D 7E C1 EF AA 16 8B 56 B2 C5 D0 43 F2"

[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"

The process %original file name%.exe:1244 makes changes in the system registry.
The Worm creates and/or sets the following values in system registry:

[HKLM\SOFTWARE\Microsoft\Cryptography\RNG]
"Seed" = "75 2A 5C C0 7F 45 9E E8 26 E1 54 05 47 DB D0 F9"

[HKCU\Software\VB and VBA Program Settings\INSTALL\DATE]
"S2UR40XGHV" = "June 20, 2014"

[HKCU\Software\VB and VBA Program Settings\SrvID\ID]
"S2UR40XGHV" = "CoinAPISV"

[HKCU\Software\Microsoft\Active Setup\Installed Components\{0ABC2DB1-6BDB-7CD1-B9A3-FDCC9ABFD78C}]
"StubPath" = "%Documents and Settings%\%current user%\Application Data\Nvidia Physics Drivers Signed\aticlexx.exe"

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

[HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\policies\Explorer\Run]
"Nvidia Physics Drivers Inc" = "%Documents and Settings%\%current user%\Application Data\Nvidia Physics Drivers Signed\aticlexx.exe"

[HKLM\SOFTWARE\Microsoft\Active Setup\Installed Components\{0ABC2DB1-6BDB-7CD1-B9A3-FDCC9ABFD78C}]
"StubPath" = "%Documents and Settings%\%current user%\Application Data\Nvidia Physics Drivers Signed\aticlexx.exe"

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]
"Nvidia Physics Drivers Inc" = "%Documents and Settings%\%current user%\Application Data\Nvidia Physics Drivers Signed\aticlexx.exe"

[HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run]
"Nvidia Physics Drivers Inc" = "%Documents and Settings%\%current user%\Application Data\Nvidia Physics Drivers Signed\aticlexx.exe"
