Verdict:	Malicious activity
Threats:	AsyncRAT is a RAT that can monitor and remotely control infected systems. This malware was introduced on Github as a legitimate open-source remote administration software, but hackers use it for its many powerful malicious functions. DCrat, also known as Dark Crystal RAT, is a remote access trojan (RAT), which was first introduced in 2018. It is a modular malware that can be customized to perform different tasks. For instance, it can steal passwords, crypto wallet information, hijack Telegram and Steam accounts, and more. Attackers may use a variety of methods to distribute DCrat, but phishing email campaigns are the most common. 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 >>>
