Verdict:	Malicious activity
Threats:	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. Trojans are a group of malicious programs distinguished by their ability to masquerade as benign software. Depending on their type, trojans possess a variety of capabilities, ranging from maintaining full remote control over the victim’s machine to stealing data and files, as well as dropping other malware. At the same time, the main functionality of each trojan family can differ significantly depending on its type. The most common trojan infection chain starts with a phishing email.
