- A
Using LinkFinder to extract endpoints from JavaScript
Correct. LinkFinder parses JS files for URLs and endpoints.
- B
Using Wappalyzer to identify frameworks
Why wrong: Wappalyzer does not extract secrets or endpoints from JS.
- C
Using SecretFinder to search for API keys and secrets
Correct. SecretFinder detects patterns for secrets.
- D
Using Gobuster to bruteforce directories
Why wrong: Gobuster is for discovering hidden directories, not for JS analysis.
- E
Manually examining JavaScript source files
Correct. Manual review can find hardcoded keys and endpoints.

PT0-002 Practice Question: Information Gathering and Vulnerability Scanning
This PT0-002 practice question tests your understanding of information gathering and vulnerability scanning. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A penetration tester is analyzing a web application's JavaScript files for hardcoded secrets and API endpoints. Which THREE techniques or tools are MOST effective for this purpose? (Select THREE.)

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Using LinkFinder to extract endpoints from JavaScript
LinkFinder is a Python tool specifically designed to extract API endpoints and URLs from JavaScript files by parsing the JS content and using regular expressions to identify potential endpoints. This makes it highly effective for discovering hidden or undocumented API routes that may be exposed in client-side code.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the distinction between tools that passively extract information from existing files (LinkFinder, SecretFinder) versus tools that actively bruteforce or fingerprint server-side resources (Gobuster, Wappalyzer), leading candidates to select tools that serve different phases of the penetration test.
Detailed technical explanation
How to think about this question
LinkFinder works by fetching JavaScript files, then applying regex patterns like /api/ or /v1/ to extract potential endpoints, while SecretFinder uses regex patterns for common API key formats (e.g., AWS keys, Google API keys) and high-entropy strings. Manual examination remains critical because automated tools may miss obfuscated or dynamically constructed strings, and real-world JavaScript often contains minified code that requires careful review to spot secrets embedded in comments or concatenated variables.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A developer is choosing between AES-256 (symmetric) and RSA-2048 (asymmetric) for encrypting a large file that will be sent to a partner. Symmetric encryption is fast but requires key exchange; asymmetric is slower but solves the key distribution problem. A hybrid approach — encrypt the file with AES, encrypt the AES key with RSA — is standard. Questions like this test whether you understand when each approach applies.
