The correct answer is OSINT (Open-Source Intelligence) because this technique involves collecting publicly accessible information—such as internal project names, server IPs, and database credentials found in a public GitHub repository—without any direct interaction with the target. On the CompTIA PenTest+ PT0-002 exam, this scenario tests your ability to distinguish passive reconnaissance from active methods like scanning or enumeration; a common trap is confusing OSINT with social engineering, but remember that OSINT relies solely on pre-existing public data, not human interaction. To lock it in, use the mnemonic “GitHub Gives OSINT Gold”—if you can find it with a simple search, it’s open-source intelligence.
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.
During reconnaissance, a penetration tester discovers a public GitHub repository belonging to the target organization. The repository contains internal project names, server IP addresses, and code comments with database credentials. Which reconnaissance technique does this represent?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
OSINT (Open-Source Intelligence)
The discovery of a public GitHub repository containing internal project names, server IP addresses, and database credentials is a classic example of OSINT (Open-Source Intelligence). OSINT involves collecting and analyzing publicly available information from sources like code repositories, social media, and websites to gain insights about a target without direct interaction. This technique leverages the fact that sensitive data is often inadvertently exposed in public repositories, making it a passive reconnaissance method.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
OSINT (Open-Source Intelligence)
Why this is correct
OSINT gathers information from public sources like GitHub, which can leak internal details without interacting with the target's systems.

✗
DNS enumeration
Why it's wrong here
DNS enumeration queries DNS servers for records; it does not involve scanning code repositories.
✗
Port scanning
Why it's wrong here
Port scanning actively probes target IPs for open ports, not for information in public repositories.
✗
Social engineering
Why it's wrong here
Social engineering involves manipulating people to divulge information; this scenario uses a publicly available code repository.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse OSINT with active reconnaissance techniques like DNS enumeration or port scanning, failing to recognize that passive collection from public sources (like GitHub) is a distinct OSINT method.

Detailed technical explanation
How to think about this question
OSINT in this context often involves scraping GitHub APIs (e.g., `/search/code`) or using tools like `gitrob` or `truffleHog` to automatically detect secrets in repositories. A subtle behavior is that even deleted commits or branches can be recovered via Git history, meaning credentials might persist in the repository's commit log long after they are removed from the current codebase. In real-world engagements, attackers frequently use OSINT to map internal network structures from exposed configuration files, bypassing the need for active scanning.

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
An employee at a financial services firm receives an email that appears to come from the IT helpdesk, asking them to reset their password via a link. The link leads to a convincing fake portal that harvests credentials. Security teams use phishing simulations and security-awareness training to reduce this attack vector. Questions like this test whether you can identify social engineering techniques and appropriate controls.
