Ethical Hacking - Dos attacks on different services.
https://github.com/samglish/technicalDos
The different tools

  1. Metasploit
  2. Nmap NSE
  3. Exploit database
  4. Scapy

DOS/DDOS categories

  • Session abuse.
  • Attacks based on packet volume.
  • Protocol-based attacks.
  • Attacks based on the application layer.

We will send a packet with a TTL 0, it is a malformed packet which will create confusion for the target server then a service denial we will send millions of requests.

Format end(dst="ip", ttl=0)/TCP(),iface="",count=2000)

see your ip_adress and nerwork interface

ifconfig

adresse cible :
malformed packet : use TTL 0
