CEH Practice Question: Malware, Social Engineering and Network Attacks
During a penetration test, an analyst uses a tool that sends forged ARP replies to associate the attacker's MAC address with the IP address of the default gateway. This technique allows the attacker to intercept traffic. Which tool is commonly used for this purpose?
⚠ Common exam trap
It's easy for candidates to confuse passive sniffing tools (like Wireshark or tcpdump) with active attack tools, assuming any packet capture tool can also inject packets, but only dedicated MITM tools like Ettercap implement ARP spoofing.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Ettercap
Ettercap is a comprehensive suite for man-in-the-middle attacks on LAN. It supports ARP poisoning, where it sends forged ARP replies to associate the attacker's MAC address with the IP address of the default gateway. This causes the target's traffic destined for the gateway to be sent to the attacker, allowing interception and modification of packets.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Ettercap
Why this is correct
Ettercap performs ARP poisoning and MITM attacks.
- ✗
Wireshark
Why it's wrong here
Wireshark is a packet analyzer, not an ARP poisoning tool.
- ✗
Nmap
Why it's wrong here
Nmap is a network scanner.
- ✗
tcpdump
Why it's wrong here
tcpdump captures packets.
