Networking: Routing Table Manipulation | DNS Spoofing

  1. Through Manipulation of the routing table.
  2. DNS spoofing locally using the internal hosts.
  1. OS and a device to run the OS on both the side, i.e. a computer with an OS of choice, in our case the two devices are the client (us with our computer) and the server computer (Google/Facebook and their server systems) and the OS of my choice for this task is RHEL8.
  2. NIC, which I assume you will have as you are using the internet, same applies to them(Google/Facebook).
  3. Internet Protocol, i.e. a set of agreed upon rules for communication between two parties. We are going to use IPv4 for our operation.
  4. A connection on the physical layer via cables, routers, switches etc. between us and them(Google/Facebook).
  5. Us and them(Google/Facebook) must be in a single network.
