A penetration tester is analyzing a PowerShell script that uses Invoke-WebRequest and Invoke-RestMethod to interact with a target web service. The script parses JSON responses to extract session tokens and then uses those tokens in subsequent requests. Which attack technique is this script most likely performing?
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.
Distractor review
Brute-forcing web application login credentials.
Brute-forcing typically involves submitting many login attempts with different credentials. The script's use of session tokens and API requests suggests a more targeted approach against API endpoints, not a brute-force attack.
Best answer
Exploiting an API by manipulating request parameters and observing responses.
The script dynamically extracts session tokens and reuses them, which is common when testing APIs for parameter manipulation, privilege escalation, or injection flaws. It allows the tester to bypass authentication and test authenticated endpoints.
Distractor review
Performing a SQL injection attack on a web form.
SQL injection usually involves injecting malicious SQL strings into input fields. The script's use of JSON parsing and token management does not align with classic SQL injection payloads.
Distractor review
Conducting a directory traversal attack to read arbitrary files.
Directory traversal attacks typically manipulate file paths in requests. The script focuses on API interactions and tokens, not file reading.
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: Exploiting an API by manipulating request parameters and observing responses. — The script's behavior suggests it is interacting with an API, manipulating parameters in requests, and maintaining session state via tokens. This is characteristic of testing for API vulnerabilities such as improper input validation, authentication bypasses, or parameter tampering. The script is likely attempting to exploit business logic flaws or authorization weaknesses in the API.
