CompTIA Updated PT0-003 Exam Questions and Answers by izaiah

Given a short assessment timeline and the need to identify hard-coded credentials in a large codebase, using an automated tool designed for this specific purpose is the most effective approach. Here’s an explanation of each option:

Run TruffleHog against a local clone of the application (Answer: A):

TruffleHog is a specialized tool that scans for hard-coded secrets such as passwords, API keys, and other sensitive data within the code repositories.

Effectiveness: It quickly and automatically identifies potential credentials and other sensitive information across thousands of files, making it the most efficient choice under time constraints.

The presence of SMB (port 445) and MSRPC (port 135) indicates potential Windows network services that could be vulnerable to misconfigurations or exploits.

Enumerate shares and search for vulnerabilities on SMB (Option B):

SMB (Server Message Block) allows file and printer sharing. Misconfigured or open shares could contain sensitive data.

Tools like enum4linux or smbclient can be used to list available shares and check for anonymous access.

SMB vulnerabilities (e.g., EternalBlue - CVE-2017-0144) can be exploited for remote code execution.

The unauthorized reprinting of ID badges suggests the penetration tester is attempting physical security penetration testing to gain long-term access.

Option A (Obtain long-term, valid access) ✅: Correct. Cloning or reprinting badges allows persistent access past security checks.

Option B (Disrupt availability) ❌: There is no indication of a denial-of-service attack.

Option C (Change access for valid users) ❌: The goal is not modifying user access, but rather gaining unauthorized access.

Option D (Revoke access for valid users) ❌: The logs show new badges being printed, not revocation.

The EPSS (Exploit Prediction Scoring System) estimates how likely a vulnerability is to be exploited. Higher EPSS scores indicate a higher likelihood of exploitation.

Option A (Target 1) ✅:

EPSS 0.6 (60% chance of exploitation)

CVSS 4 (Medium severity)

✅ Best candidate since it has the highest likelihood of exploitation.

Option B (Target 2) ❌: EPSS 0.3 (30%) is lower, making it less likely to be attacked.

Option C (Target 3) ❌: EPSS 0.6 is high, but CVSS 1 is very low, meaning the vulnerability is not critical.

Option D (Target 4) ❌: CVSS 4.5 is higher, but EPSS 0.4 is lower, meaning attackers are less likely to exploit it.
