Remcos RAT (Remote Control and Surveillance) is a type of Remote Access Trojan widely used by cybercriminals to gain unauthorized access to Windows systems. Once installed, Remcos allows attackers to control infected computers remotely, enabling activities such as keylogging, screen capturing, file theft, and even activating webcams and microphones. Distributed often via phishing emails or malicious attachments, Remcos RAT is favored for its stealth and robust features, making it a significant threat to both individuals and organizations. Its modular design allows attackers to customize functionalities, evade detection, and persist on compromised systems, facilitating data breaches and further malware deployment.
