Astsu : A Network Scanner Tool

Astsu is a network scanner tool, developed in Python 3 using scapy.

How it works?

  • Scan common ports : Send a TCP Syn packet to the destination on the defined port, if the port is open, use an nmap scan to check the service running on the port and prints all the ports found.
  • Discover hosts in network : Uses as a base the router’s ip to map all possible ips. It then sends an ICMP packet to each IP, and waits for a response, if it receives any response saved in an array the IP of the online host, and when it finishes checking all hosts, prints all hosts online.
  • OS Scan : Sends an ICMP packet to the destination and waits for a response. Then, extracts the TTL from the destination response and checks the possible OS in a list, if have founded, prints it.
