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:2244

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

%original file name%.exe:3504

Mutexes

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

File activity

The process %original file name%.exe:3504 makes changes in the file system.

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

C:\Users\"%CurrentUserName%"\AppData\Roaming\svchost.exe (1721 bytes)
C:\Users\"%CurrentUserName%"\AppData\Roaming\logs (34 bytes)

Registry activity

The process %original file name%.exe:3504 makes changes in the system registry.

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

[HKCU\Software\VB and VBA Program Settings\SrvID\ID]
"JI5KHIW76B" = "svchost"

[HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\policies\Explorer\Run]
"Svchost" = "C:\Users\"%CurrentUserName%"\AppData\Roaming\svchost.exe"

[HKCU\Software\VB and VBA Program Settings\INSTALL\DATE]
"JI5KHIW76B" = "November 2, 2016"

[HKLM\SOFTWARE\Microsoft\Active Setup\Installed Components\{72EDD76C-E87E-A45B-6AEC-A51DBBD1BE6A}]
"StubPath" = "C:\Users\"%CurrentUserName%"\AppData\Roaming\svchost.exe"

[HKCU\Software\Microsoft\Active Setup\Installed Components\{72EDD76C-E87E-A45B-6AEC-A51DBBD1BE6A}]
"StubPath" = "C:\Users\"%CurrentUserName%"\AppData\Roaming\svchost.exe"

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]
"Svchost" = "C:\Users\"%CurrentUserName%"\AppData\Roaming\svchost.exe"

[HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run]
"Svchost" = "C:\Users\"%CurrentUserName%"\AppData\Roaming\svchost.exe"

C:\Users\"%CurrentUserName%"\AppData\Roaming\svchost.exe (1721 bytes)
C:\Users\"%CurrentUserName%"\AppData\Roaming\logs (34 bytes)
Delete the following value(s) in the autorun key (How to Work with System Registry):
[HKCU\Software\Microsoft\Windows\CurrentVersion\Run]
"Svchost" = "C:\Users\"%CurrentUserName%"\AppData\Roaming\svchost.exe"

[HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run]
"Svchost" = "C:\Users\"%CurrentUserName%"\AppData\Roaming\svchost.exe"
