Threats:	DarkComet RAT is a malicious program designed to remotely control or administer a victim's computer, steal private data and spy on the victim. Remote access trojans (RATs) are a type of malware that enables attackers to establish complete to partial control over infected computers. Such malicious programs often have a modular design, offering a wide range of functionalities for conducting illicit activities on compromised systems. Some of the most common features of RATs include access to the users’ data, webcam, and keystrokes. This malware is often distributed through phishing emails and links. Malware Trends Tracker >>>
