![]() ![]() ![]() Once the target has unwittingly infected their device, the RAT spawns a new malicious process or hijacks a legitimate process to evade detection and initializes a connection back to a remote command and control server (C2). They can also be installed via attack vectors such as vulnerability exploits, direct physical access, or a USB key drop as bait. Trojans can be distributed via phishing or malspam campaigns or made available for download on malicious and even legitimate websites.

Trojans are executable applications, documents, or files with embedded executable code appearing as typical, innocuous functions. RATs are a subcategory of Trojan malware. Some RATs are specifically designed malware, but many legitimate network administration tools intended for legitimate network operations can also be used as RATs as they offer remote system control capabilities. RAT malware can infect any device with network access, including desktop and laptop computers, mobile phones, tablets, IoT devices, peripherals such as printers, faxes, home security products, and smart home devices-and can be designed for any standard operating system. RATs are a backdoor to a system and are practical tools for stealing information such as files, keystrokes, passwords, screenshots, and webcam video or audio, and can be leveraged to conduct other attacks, such as lateral movement through a network and to import additional malware with extended capabilities like ransomware. A remote access Trojan (RAT) is a type of malware that allows a threat actor to execute commands on an infected system from a remote location-they do not need physical access to control the system. ![]()
