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:3308

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

%original file name%.exe:1652
vbc.exe:3148
Explorer.EXE:284

Mutexes

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

File activity

The process %original file name%.exe:3308 makes changes in the file system.
The Trojan creates and/or writes to the following file(s):

C:\Users\"%CurrentUserName%"\AppData\Local\Temp\vbc.exe (7596 bytes)

The process vbc.exe:3148 makes changes in the file system.
The Trojan creates and/or writes to the following file(s):

C:\Users\"%CurrentUserName%"\AppData\Roaming\RTZ4JLGB75.exe (1537 bytes)
C:\Users\"%CurrentUserName%"\AppData\Roaming\Rs (32 bytes)

Registry activity

The process vbc.exe:3148 makes changes in the system registry.
The Trojan creates and/or sets the following values in system registry:

[HKCU\Software\Microsoft\Active Setup\Installed Components\{FFEFC70F-71EE-1ED1-3EC2-DA4EE4F6B1FD}]
"StubPath" = "C:\Users\"%CurrentUserName%"\AppData\Roaming\RTZ4JLGB75.exe"

[HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\policies\Explorer\Run]
"Windows Defender" = "C:\Users\"%CurrentUserName%"\AppData\Roaming\RTZ4JLGB75.exe"

[HKCU\Software\VB and VBA Program Settings\INSTALL\DATE]
"E523PYDOGH" = "September 1, 2017"

[HKLM\SOFTWARE\Microsoft\Active Setup\Installed Components\{FFEFC70F-71EE-1ED1-3EC2-DA4EE4F6B1FD}]
"StubPath" = "C:\Users\"%CurrentUserName%"\AppData\Roaming\RTZ4JLGB75.exe"

[HKCU\Software\VB and VBA Program Settings\SrvID\ID]
"E523PYDOGH" = "KK"

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]
"Windows Defender" = "C:\Users\"%CurrentUserName%"\AppData\Roaming\RTZ4JLGB75.exe"

[HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run]
"Windows Defender" = "C:\Users\"%CurrentUserName%"\AppData\Roaming\RTZ4JLGB75.exe"
