Since RATs give hackers administrative access to infected computers, they’re free to alter or download any files on a whim. That means a hacker with a RAT can wipe your hard drive, download illegal content from the internet through your computer, or place additional malware onto your computer. Hackers can also control your computer remotely to perform embarrassing or illegal actions online in your name or use your home network as a proxy server to commit crimes anonymously.

A hacker can also use a RAT to take control of a home network and create a botnet. Essentially, a botnet allows a hacker to utilize your computer resources for super nerdy (and often illegal) tasks, like DDOS attacks, Bitcoin mining, file hosting, and torrenting. Sometimes, this technique is utilized by hacker groups for the sake of cyber crime and cyber warfare. A botnet that’s comprised of thousands of computers can produce a lot of Bitcoin, or take down large networks (or even an entire country) through DDOS attacks.

Of course, you should also enable your anti-virus software. Windows Defender is included with your PC (and it’s honestly a great anti-virus software), but if you feel the need for some extra security, then you can download a commercial anti-virus software like Kaspersky or Malwarebytes.
