Summary: Worm. A program that is primarily replicating on networks or removable drives.
Dynamic Analysis
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):
svhost.exe:272
%original file name%.exe:944
The Worm injects its code into the following process(es):No processes have been created.
File activity
The process svhost.exe:272 makes changes in the file system.
The Worm creates and/or writes to the following file(s):
%Documents and Settings%\%current user%\Local Settings\Temp\ZGJTFG0CPC.exe (3860 bytes)
%Documents and Settings%\%current user%\Local Settings\Temp\keylog (34 bytes)
The process %original file name%.exe:944 makes changes in the file system.
The Worm creates and/or writes to the following file(s):
%WinDir%\Temp\svhost.exe (7547 bytes)
%System%\drivers\etc\hosts (193 bytes)
Registry activity
The process svhost.exe:272 makes changes in the system registry.
The Worm creates and/or sets the following values in system registry:
[HKLM\SOFTWARE\Microsoft\Cryptography\RNG]
"Seed" = "27 4D ED DF 32 72 48 84 AA 44 61 C0 E4 A4 7B 70"
[HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\policies\Explorer\Run]
"dsfsesf" = "C:\DOCUME~1\"%CurrentUserName%"\LOCALS~1\Temp\ZGJTFG0CPC.exe"
[HKCU\Software\VB and VBA Program Settings\INSTALL\DATE]
"DY4E2I88KB" = "June 12, 2014"
[HKLM\SOFTWARE\Microsoft\Active Setup\Installed Components\{BFA53BDE-F52F-BEA1-8496-00FF1BD9CDBA}]
"StubPath" = "C:\DOCUME~1\"%CurrentUserName%"\LOCALS~1\Temp\ZGJTFG0CPC.exe"

[HKCU\Software\VB and VBA Program Settings\SrvID\ID]
"DY4E2I88KB" = "EscV2"
To automatically run itself each time Windows is booted, the Worm adds the following link to its file to the system registry autorun key:
[HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run]
"dsfsesf" = "C:\DOCUME~1\"%CurrentUserName%"\LOCALS~1\Temp\ZGJTFG0CPC.exe"
[HKCU\Software\Microsoft\Windows\CurrentVersion\Run]
"dsfsesf" = "C:\DOCUME~1\"%CurrentUserName%"\LOCALS~1\Temp\ZGJTFG0CPC.exe"
The process %original file name%.exe:944 makes changes in the system registry.
The Worm creates and/or sets the following values in system registry:
[HKLM\SOFTWARE\Microsoft\Cryptography\RNG]
"Seed" = "C9 4B 20 1B E8 E3 CB DE 52 8B 8C 4E 00 71 8C 90"
[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"

- Run a full scan of your computer.
Manual removal*
- Terminate malicious process(es) (How to End a Process With the Task Manager):
svhost.exe:272
%original file name%.exe:944 - Delete the original Worm file.
- Delete or disinfect the following files created/modified by the Worm:
%Documents and Settings%\%current user%\Local Settings\Temp\ZGJTFG0CPC.exe (3860 bytes)
%Documents and Settings%\%current user%\Local Settings\Temp\keylog (34 bytes)
%WinDir%\Temp\svhost.exe (7547 bytes)
%System%\drivers\etc\hosts (193 bytes) - Delete the following value(s) in the autorun key (How to Work with System Registry):
[HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run]
"dsfsesf" = "C:\DOCUME~1\"%CurrentUserName%"\LOCALS~1\Temp\ZGJTFG0CPC.exe"
[HKCU\Software\Microsoft\Windows\CurrentVersion\Run]
"dsfsesf" = "C:\DOCUME~1\"%CurrentUserName%"\LOCALS~1\Temp\ZGJTFG0CPC.exe" - Restore the original content of the HOSTS file (%System%\drivers\etc\hosts): 127.0.0.1 localhost
- Find and delete all copies of the worm's file together with "autorun.inf" scripts on removable drives.
