During a penetration test, a tester has access to a Windows domain-joined machine. The tester finds that the machine is running a service that uses named pipes for interprocess communication. The tester wants to perform a relay attack to capture authentication credentials. Which of the following conditions is necessary for an SMB relay attack to succeed?

Answer choices

Why each option matters

Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.

A

Best answer

SMB signing must be disabled or not enforced

SMB signing provides integrity and authentication checks; if it is disabled or not enforced, the relayed authentication succeeds because the server does not verify the source of the message.

B

Distractor review

The attacker must be on the same subnet

While being on the same subnet simplifies network access, SMB relay can work across different subnets if routing allows the relaying of traffic.

C

Distractor review

The target must have a publicly available SMB share

The presence of a public SMB share is not required; the relay attack works as long as the target is reachable and accepts SMB connections.

D

Distractor review

The attacker must have admin privileges on the relay machine

Admin privileges on the relay machine are unnecessary; the relay process only needs to forward authentication packets, which can be done with standard user privileges.

Common exam trap

Common exam trap: authentication is not authorization

Logging in proves the user can authenticate. It does not automatically mean the user is allowed to enter privileged or configuration mode. Watch for AAA authorization, privilege level and command authorization details.

Technical deep dive

How to think about this question

This kind of question is testing the difference between identity and permission. A user may successfully log in to a router because authentication is working, but still fail to enter configuration mode because authorization is missing, misconfigured or mapped to a lower privilege level.

KKey Concepts to Remember

  • Authentication checks who the user is.
  • Authorization controls what the user is allowed to do after login.
  • Privilege levels affect access to EXEC and configuration commands.
  • AAA, TACACS+ and RADIUS can separate login success from command access.

TExam Day Tips

  • Do not assume successful login means full administrative access.
  • Look for words such as cannot enter configuration mode, privilege level, authorization or command access.
  • Separate login problems from permission problems before choosing the answer.

FAQ

Questions learners often ask

What does this PT0-002 question test?

Authentication checks who the user is.

What is the correct answer to this question?

The correct answer is: SMB signing must be disabled or not enforced — SMB relay attacks work by capturing an authentication attempt and relaying it to another server. For the attack to succeed, SMB signing must be disabled or not enforced on the target server; otherwise, the relayed authentication will be rejected. Being on the same subnet is beneficial but not strictly necessary if routing is in place. Public SMB shares or admin privileges on the relay machine are not required, as the attack relies on captured credentials, not local privileges.
