What type of malware allows an attacker to remotely control an infected computer?

The most accurate answer is a Remote Access Trojan (RAT). This type of malware is specifically designed to provide an attacker with remote control over an infected computer. Once a RAT infects a system, the attacker can perform various actions, such as accessing files, logging keystrokes, capturing screenshots, or even using the webcam to monitor the user without their knowledge.

RATs are particularly dangerous because they often masquerade as legitimate software or are delivered through phishing emails, making it easy for users to unwittingly install them. The remote access capabilities allow attackers to exploit the system extensively, making it a potent tool for espionage or data theft.

In contrast to RATs, other types of malware mentioned serve different purposes. While a backdoor virus can also allow access to a system, it is primarily a method of bypassing authentication, rather than a dedicated tool for remote access. Worms are designed to replicate and spread across networks, focusing on self-propagation rather than providing control to an attacker. Spyware is intended to gather information about a user without their consent, such as tracking browsing habits or stealing personal information, rather than providing remote control of the system. Thus, the specific focus of a RAT on remote management demonstrates why it is
