The scenario is following:

  1. A telnet server which has ACL implemented for telnet connections.
  2. A hacker spoofs IP and tries to connect to the telnet server.

Consider that the hacker knows the password. Will he/she be able to spoof the IP and establish a telnet connection over the internet successfully?

What will be the outcome the actual IP holder is active when the hacker is performing this attack?

Would like to know that what will be the case on every layer of OSI model in any possible outcome.

  • How would the attacker receive the packets sent in response by the server? – schroeder Jun 25 '19 at 19:04
