Final answer:
The statement that a Remote Access Trojan (RAT) can monitor user actions, alter settings, browse and copy files, and access other networked computers is true. Hackers deploy RATs using deceptive techniques like social engineering to gain unauthorized access and control over a victim's computer.
Step-by-step explanation:
True, a Remote Access Trojan (RAT) can indeed perform a variety of malicious activities that compromise the security and functionality of a computer. Hackers use RATs to gain unauthorized access to a victim's computer and then carry out actions such as monitoring user activity, changing system settings, browsing and copying files, and further accessing other connected devices on the network. This type of malware is particularly insidious because it can operate in stealth, giving the attacker control over the computer without the user's knowledge.
Hackers often deploy RATs by tricking users into clicking on malicious links or downloading infected attachments. These tactics are part of the larger scheme of 'social engineering' that attackers use to lure individuals into compromising their own security. Therefore, it's crucial for users to be vigilant against suspicious links and emails, and to maintain robust security practices to protect against such threats.
