Scrappy

scrappy is a tool based on the library "scapy". This tool has a few base features.

features

1. Discover hosts

This feature will scan a network range for living hosts. This can be done in multiple ways:

  • ICMP ping
    ! A lot of firewalls block ICMP packets.
  • UDP ping
  • TCP ping
  • IP Protocol ping
  • ARP ping
    pinging with the ARP protocol is faster and more reliable than the other protocols

2. Discover services

To discover services running on a host, we will send packages to the different ports. Looking at the (lack of) answer, will clarify the status of a port. We scan all ports from 1 to 1024.

3. Remote OS detection

Linux kernel and Windows have different time to life in their ICMP packets. We can extract this from the answer on our sent ICMP packet.

4. PCAP analyse

We analyse and scan the network for HTTP trafic. You can do this for a particular host and for a network range
