Security researchers at the iSwatlab have conducted an analysis of a few methods for the creation of some malicious payloads or shellcodes. These payloads must be used to create a remote connection between the victims machine and the attacker’s machine that wants to listen and, once a connection is successfully established, obtain sensitive information or make an attack to that user. The creation was made by using some free tools, running on a Kali Linux machine, that are: Metasploit, TheFatRat and Poison Scanner.”]
