The answer is to find SUID binaries and inspect unusual or writable executables. These checks are foundational for Linux privilege escalation enumeration because SUID (Set Owner User ID) binaries execute with the file owner’s permissions—often root—so any misconfigured or custom SUID file can be exploited to gain elevated access. Similarly, inspecting writable executables reveals scripts or binaries that a low-privilege user can modify, potentially injecting malicious code that runs with higher privileges. On the CompTIA PenTest+ PT0-002 exam, this concept tests your ability to identify common misconfigurations rather than relying on complex exploits; a frequent trap is overlooking world-writable scripts in cron jobs or custom SUID binaries left by developers. A useful memory tip is “SUID and write—escalate your might,” reminding you that SUID bits and writable executables are two of the quickest paths from low-privilege to root.
PT0-002 Attacks and Exploits Practice Question
This PT0-002 practice question tests your understanding of attacks and exploits. Compare every option against the stated constraints before choosing — the best answer satisfies all requirements, not just the most obvious one. 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 tester has low-privilege shell access on a Linux server. Which two checks are most appropriate for local privilege escalation enumeration? (Choose 2.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Review sudo privileges with sudo -l.
Option A is correct because `sudo -l` lists the commands the current user can execute with elevated privileges, which is a standard first step in privilege escalation enumeration. If the user has sudo rights to any command without a password or with a known password, they can potentially run that command as root, leading to full system compromise.
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.
✓
Review sudo privileges with sudo -l.
Why this is correct
Misconfigured sudo rules are a common privilege escalation path.

✓
Find SUID binaries and inspect unusual or writable executables.
Why this is correct
SUID misconfiguration can allow privilege escalation.
Related concept
Read the scenario before looking for a memorised answer.
✗
Run a full SYN scan of the public IP range.
Why it's wrong here
External port scanning does not enumerate local privilege escalation paths.
✗
Send phishing emails to the finance department.
Why it's wrong here
That is social engineering, not local Linux privilege escalation enumeration.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse network scanning or social engineering with local enumeration techniques, forgetting that the question explicitly states the tester already has low-privilege shell access on the target server.
Detailed technical explanation
How to think about this question
SUID binaries (setuid) execute with the file owner's permissions, often root; finding unusual or writable SUID files (e.g., via `find / -perm -4000 -type f 2>/dev/null`) can reveal exploitable programs like `nmap`, `vim`, or custom scripts that allow command injection or shell spawning. In real-world scenarios, misconfigured sudoers entries (e.g., allowing `sudo /usr/bin/less` without a password) can be exploited by using `!` to execute shell commands within the pager.

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.
