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:3708

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

%original file name%.exe:2216

Mutexes

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

File activity

The process %original file name%.exe:2216 makes changes in the file system.
The Trojan creates and/or writes to the following file(s):

C:\Users\"%CurrentUserName%"\AppData\Roaming\ms13s.exe (849 bytes)
C:\Users\"%CurrentUserName%"\AppData\Roaming\k-one (33 bytes)

Registry activity

The process %original file name%.exe:2216 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]
"OQ5R2IF9S3" = "Ms13"

[HKCU\Software\Microsoft\Active Setup\Installed Components\{FCC7A5E0-ABD7-659B-EC78-4ABDEA2EFB7C}]
"StubPath" = "C:\Users\"%CurrentUserName%"\AppData\Roaming\ms13s.exe"

[HKCU\Software\VB and VBA Program Settings\INSTALL\DATE]
"OQ5R2IF9S3" = "February 10, 2018"

[HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\policies\Explorer\Run]
"system32" = "C:\Users\"%CurrentUserName%"\AppData\Roaming\ms13s.exe"

[HKLM\SOFTWARE\Microsoft\Active Setup\Installed Components\{FCC7A5E0-ABD7-659B-EC78-4ABDEA2EFB7C}]
"StubPath" = "C:\Users\"%CurrentUserName%"\AppData\Roaming\ms13s.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]
"system32" = "C:\Users\"%CurrentUserName%"\AppData\Roaming\ms13s.exe"

[HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run]
"system32" = "C:\Users\"%CurrentUserName%"\AppData\Roaming\ms13s.exe"
