What are RATs and how can you protect yourself from them?

RAS trojan

RATs (Remote Access Trojans) are different types of malicious software that can enter computers and be controlled remotely.

RATs are used to remotely control your infected computers

They have nothing to do with, for example, IT support teams performing remote control activities on user devices to install software updates or troubleshoot problems. In this case, the user grants permission for remote access.

However, RAT programs are used for criminal purposes to enter users’ computers and mobile devices without them offering their authorization. They are used to steal data, usurp identities, gain access to bank codes or other platforms that ultimately make a mess with what your team occupies.

The main problem is that these RATs are usually installed in applications such as games, programs downloaded from the Internet, or files and documents received from an email that appears normal and legitimate to the ordinary user. However, if you download and install a program that contains a RAT trojan, you open the door to free and unrestricted access for attackers who want to take control of your computer.

A RAT can be installed on the computer without the knowledge of the user. In general, this type of malware does not leave any trace of installation or visible damage, nor does it register any noticeable or strange changes on the computer. It is a kind of silent trojan that only watches and acts when the user doesn’t know, even when the computer is sleeping or turned off.

How do you protect yourself from RAT malware?

You can avoid falling victim to RATs by being careful with computing devices. Here are some tips to avoid installing a RAT or to minimize its impact:

-Install an antivirus: A security system installed on the device is essential. This needs to be properly updated to detect intruders or malicious software on the system.

– Care when downloading– Before pressing the button to download a file from a website, check that it is safe and reliable. If you notice anything strange on the download page or in the email that came in with an attachment it is ideal to avoid the download. Note that the user may have a RAT on their computer and not know about it, even if the return address is legitimate. He is the one who remotely controls the computer that sent the email with malicious software installed. When in doubt, ask the user by phone or other means so that communications cannot be remotely intercepted.

-Block systems: It is important to use strong passwords that are difficult to encrypt and not to repeat them in multiple accounts or profiles. You can also use two tier verification systems used by many platforms like WhatsApp, Twitter, Instagram, Facebook, and also by operating systems like Windows, Mac, Android and iOS.

– Constantly updated– When operating systems are up to date, so are security systems. This way, you will be kept up to date with the maximum level of protection, in an alert state and in a safe response to RAT or other attempted attack that your device or computer might suffer.
