Quick Answer
The answer is Backdoor. A Remote Access Trojan (RAT) is specifically designed to provide an attacker with persistent remote control over a victim machine, functioning as a backdoor that bypasses normal authentication to grant covert, ongoing access. Unlike other trojans focused on data theft or destruction, the RAT’s core purpose is to establish a hidden communication channel, often with built-in persistence mechanisms like registry modifications or scheduled tasks to survive reboots. On the Certified Ethical Hacker CEH exam, this concept tests your understanding of malware classification and attack lifecycle phases—specifically the “maintaining access” stage. A common trap is confusing a RAT with a simple keylogger or downloader; remember that the defining feature is the backdoor for remote control, not just information capture. To lock it in: think “RAT = Remote Access Trojan = Backdoor for persistent control.”
This CEH practice question tests your understanding of malware, social engineering and network 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.
During a penetration test, an attacker gains access to a system and wants to maintain persistent remote control. Which type of Trojan is specifically designed for this purpose?
Ransomware
Why wrong: Ransomware encrypts files for ransom, not remote control.
Backdoor
Correct. A backdoor Trojan provides unauthorized remote access to the system.
Keylogger
Why wrong: Keyloggers capture keystrokes, not remote control.
Downloader
Why wrong: Downloader Trojans fetch additional malware, but do not provide direct remote control.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Backdoor
A Remote Access Trojan (RAT) provides the attacker with remote control over the victim machine, often with features for persistence and stealth.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Ransomware
Why it's wrong here
Ransomware encrypts files for ransom, not remote control.
Backdoor
Why this is correct
Correct. A backdoor Trojan provides unauthorized remote access to the system.

Common exam traps
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A practitioner preparing for the CEH exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.

Same concept, more angles
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. Which TWO of the following are features of a Remote Access Trojan (RAT)?
hardWhy D: A Remote Access Trojan (RAT) is designed to provide an attacker with covert remote control over an infected system, often including a backdoor to bypass standard authentication mechanisms. This allows the attacker to execute commands, exfiltrate data, or use the system as a pivot point, which directly aligns with options D and E.
