This project is about creating a polymorphic blending attack to exploit a target machine while bypassing the detection of a Network Intrusion Detection System (NIDS). The attack makes use of captured network traffic packets which are considered normal to the NIDS as a baseline and mimics its byte frequency. The attacker then makes use of a man in the middle attack to send the attack over to the server. The server gets compromised and the attack is a success without getting detected by the NIDS.
