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:1704
The Worm injects its code into the following process(es):
%original file name%.exe:3508
Mutexes
The following mutexes were created/opened:
No objects were found.
File activity
The process %original file name%.exe:3508 makes changes in the file system.
The Worm creates and/or writes to the following file(s):
C:\Users\"%CurrentUserName%"\AppData\Roaming\TIYZ5K70IQ.exe (1647 bytes)
C:\Users\"%CurrentUserName%"\AppData\Roaming\Key (34 bytes)
Registry activity
The process %original file name%.exe:3508 makes changes in the system registry.
The Worm creates and/or sets the following values in system registry:
[HKCU\Software\VB and VBA Program Settings\INSTALL\DATE]
"8DZ5N7B8BO" = "October 5, 2017"
[HKCU\Software\Microsoft\Active Setup\Installed Components\{DB3DF6AA-669E-ADA6-CDDC-D3DF9EEBFDBC}]
"StubPath" = "C:\Users\"%CurrentUserName%"\AppData\Roaming\TIYZ5K70IQ.exe"
[HKCU\Software\VB and VBA Program Settings\SrvID\ID]
"8DZ5N7B8BO" = "Bot"
[HKLM\SOFTWARE\Microsoft\Active Setup\Installed Components\{DB3DF6AA-669E-ADA6-CDDC-D3DF9EEBFDBC}]
"StubPath" = "C:\Users\"%CurrentUserName%"\AppData\Roaming\TIYZ5K70IQ.exe"
[HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\policies\Explorer\Run]
"Windows" = "C:\Users\"%CurrentUserName%"\AppData\Roaming\TIYZ5K70IQ.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]
"Windows" = "C:\Users\"%CurrentUserName%"\AppData\Roaming\TIYZ5K70IQ.exe"
[HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run]
"Windows" = "C:\Users\"%CurrentUserName%"\AppData\Roaming\TIYZ5K70IQ.exe"
