What is a Trojan?
A Trojan is a program that infects a victim machine and gives control to an attacker by misleading a user into downloading it as a legitimate file. Modern trojans are loaded by other programs and gain persistence on the system allowing a malicious party to spy on the user, damage the system, steal sensitive information, or add the computer to a botnet.

What is a RAT?
A RAT, or Remote Access Tool/Trojan, is a type of malware that gives Administrative control to another user, and provides a covert backdoor to the system. This allows the remote user to do anything from keylogging, taking screenshots, changing network settings, or spy on the user via their webcam or microphone.

What is a Stealer?
A Stealer is a type of malware that is explicitly used to steal information from a user, such as bank info, logins, and other sensitive files. Stealers are typically a bit less sophisticated than other malware, and often times not include some of the more advanced persistence techiques of other malware.
