This is a Python program called GoodBoy BadBoy. As the name suggests it has two sides. Both sides are used for vulnerability assessment. The basic principle is to scan the whole network and re-direct the traffic via this program to perform checks and manipulate network packets. The good part of the code checks for open ports and their version name and numbers on the CVE Details website for known vulnerabilities. Also, the good part captures packet and saves it as .pcap file. This file can be used in IDS or in Wireshark for further analysis. While the bad part checks for user credentials send over HTTP and spoof DNS request to a specific site mentioned.
