Verdict:	Malicious activity
Threats:	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. 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. Remcos is a commercially distributed remote administration and surveillance tool that has been widely observed in unauthorized deployments, where threat actors use it to perform remote actions on compromised machines. It is actively maintained by its vendor, with new versions and feature updates released on a frequent, near-monthly basis. Remcos ist eine Malware vom Typ RAT, mit der Angreifer aus der Ferne Aktionen auf infizierten Computern durchführen können. Diese Malware ist extrem aktiv und wird fast jeden Monat mit Updates auf den neuesten Stand gebracht. Malware Trends Tracker >>>
