Question 28

Peter works as a lead penetration tester in a security service firm named Xsecurity. Recently, Peter was assigned a white-box pen test assignment testing the security of an IDS system deployed by a client. During the preliminary information gathering, Peter discovered the TTL to reach the IDS system from his end is 30. Peter created a Trojan and fragmented it in to 1-character packets using the Colasoft packet builder tool. He then used a packet flooding utility to bombard the IDS with these fragmented packets with the destination address of a target host behind the IDS whose TTL is 35. What is Peter trying to achieve?

  1. Peter is trying to bypass the IDS system using a Trojan
  2. Peter is trying to bypass the IDS system using the broadcast address
  3. Peter is trying to bypass the IDS system using the insertion attack
  4. Peter is trying to bypass the IDS system using inconsistent packets
