Troj/Agent-GZF includes functionality to access the internet and communicate with a remote server via HTTP.

When first run Troj/Agent-GZF copies itself to:

<User>\cftmon.exe

and creates the following files:

<User>\ftp34.dll
<System>\ftp34.dll

The files <System>\ftp34.dll and <User>\ftp34.dll are detected as Troj/Agent-GXN.

The following registry entries are created to run cftmon.exe and spools.exe on startup:

ntuser
<System>\drivers\spools.exe

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
autoload
<User>\cftmon.exe

The following registry entry is set or modified, so that cftmon.exe is run when files with extensions of EXE are opened/launched:

(default)
<User>\cftmon.exe "%1" %*
