for the exercise recap "Using SET to perform social engineering" can you detail how SET the social engineering toolkit can be used to send mass emails and include a malicious meterpreter session. describe what metasploit is and how we use it to catch the reverse shell, also describe what a reverse shell is. Include extra guidance on a few of the interesting functions of the meterpreter payload like keyscan_start, Keyscan_dump, uictl, screenshare and webcam_stream. Of course include the legal and ethical disclaimer.
