A remote administration tool or RAT is a program that is used by hackers or other people to connect to a computer via the Internet or across a local network remotely. A remote administration tool is based on the server and client technology. The server part runs on a controlled computer and receives commands from the client, which is installed on the remote host.
Remote administration tools are divided into malicious and legitimate applications. Parasitical RATs, also known as remote administration trojans, are very similar to backdoors and have very similar functionality. These parasites do not work on their own and must be controlled by the client. The malicious remote administration tool works in the background and hides from the user.
RATs are also used in scare campaigns — malicious actors distribute fraudulent emails to users whose login credentials were previously compromised in a data breach. The message claims that the victim's machine is hacked, and a remote administration trojan was installed that let them record compromising material via the camera. Users are then prompted to pay in Bitcoin for the hacker not to disclose the allegedly filmed content to his or her relatives and friends.
Nevertheless, it is a scam which is compiled for money grabbing, as no malware is placed on the machines that receive the email. Legitimate remote administration tools are commercial products targeted mostly at system administrators. Their primary purpose is to allow the authorized access to computers for fixing them or controlling them remotely. Nevertheless, legitimate RATs have the same functionality as parasitical programs and, therefore, can be used for obvious malicious purposes.
This type of malware gets used in targeted attacks and massive spam campaigns. Later on, after the initial infiltration, such trojans can be set to spread other malware like ransomware or cryptojacking malware. This way remote access trojans work as backdoor tools for other viruses.
RATs can also run processes in the background directly like cryptocurrency mining. Remote access tool malware can be set to steal valuable information like account logins or passwords.

They also relied on EiTest script technique, which would compromise a certain web page by injecting a specific script. Nonetheless, they only facilitated the hack of the file-encrypting threat.
