This CEH practice question tests your understanding of web application and injection attacks. 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 pentester uses Burp Suite's Intruder to perform a brute-force attack on a login form. Which THREE of the following Intruder attack types would be appropriate for testing different payload combinations?
Pitchfork
Why wrong: Pitchfork requires same number of payloads in each set, which may not be appropriate for brute force.
Sniper
Sniper is used for single payload set, iterating over positions.
Direct
Why wrong: Direct is not a standard Intruder attack type.
Cluster bomb
Cluster bomb tests all combinations of multiple payload sets.
Battering ram
Battering ram uses one payload set for all positions at once.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Sniper
Sniper uses one payload set and iterates over positions sequentially. Battering ram uses one payload set for all positions simultaneously. Pitchfork uses multiple payload sets in parallel but each set must have the same number of payloads. Cluster bomb uses multiple payload sets and tries all combinations.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Pitchfork
Why it's wrong here
Pitchfork requires same number of payloads in each set, which may not be appropriate for brute force.
Sniper
Why this is correct
Sniper is used for single payload set, iterating over positions.
Related concept
Static NAT maps one inside address to one outside address.
Direct
Why it's wrong here
Direct is not a standard Intruder attack type.
Cluster bomb
Why this is correct
Cluster bomb tests all combinations of multiple payload sets.
Related concept
Static NAT maps one inside address to one outside address.
Battering ram
Why this is correct
Battering ram uses one payload set for all positions at once.
Related concept
Static NAT maps one inside address to one outside address.
Common exam traps
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Real-world example
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
What to study next
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related CEH NAT questions on configuration and troubleshooting.
