Why is email at risk?
Since an attacker remotely accesses the computer, authenticated accounts such as email are at risk. Attackers can use email, for example, to send malicious messages to other potential victims using the authenticated email account on the remotely controlled device.

Why do attackers use RATs?
RATs have the same remote-control functionality as RDPs, but are used for malicious purposes. Attackers always code software to avoid detection, but attackers who use a RAT risk being caught when the user is in front of the device and the mouse moves across the screen. Therefore, RAT authors must create a hidden program and use it when the user is not in front of the device. To avoid detection, a RAT author will hide the program from view in Task Manager, a Windows tool that lists all the programs and processes running in memory. Attackers aim to stay hidden from detection because it gives them more time to extract data and explore network resources for critical components that could be used in future attacks.
What happens if you don't see malware in Task Manager?
If you don’t see any potential malware in Task Manager, you could still have a RAT that an author programmed to avoid detection. Good anti-malware applications detect most of the common RATs in the wild.

Vendors for these programs publish updates frequently as new malware is found in the wild.
What is remote control software?
Legitimate remote-control software exists to enable an administrator to control a device remotely.

What happens if you remove the internet from your computer?

You should always change passwords across all accounts, especially financial accounts, after removing malware from your system.
