A keylogger is a type of spyware that infects a system and has the ability to record every keystroke made on the device. This lets attackers collect personal information of victims, which may include their online banking credentials, as well as personal conversations. The most widespread vector of attack leading to a keylogger infection begins with a phishing email or link. Keylogging is also often present in remote access trojans as part of an extended set of malicious tools.

Spyware is a stealth form of malware whose primary objective is to gather sensitive information, such as personal data, login credentials, and financial details, by monitoring user activities and exploiting system vulnerabilities. Spyware operates secretly in the background, evading detection while transmitting collected data to cybercriminals, who can then use it for malicious purposes like identity theft, financial fraud, or espionage.

Stealers are a group of malicious software that are intended for gaining unauthorized access to users’ information and transferring it to the attacker. The stealer malware category includes various types of programs that focus on their particular kind of data, including files, passwords, and cryptocurrency. Stealers are capable of spying on their targets by recording their keystrokes and taking screenshots. This type of malware is primarily distributed as part of phishing campaigns.
