Chrome\Browser Password Stealers
When you run a server's client_name.jar or client_name.exe file they can execute code that steals and uploads all the saved passwords \ autofill data you have stored on your browser to their server, This is the most used technique to steal RuneScape accounts and anything else of value.
Like password stealers, Rats can be executed when running a server-client but this is much more severe and is classified as a virus that can infect your computer, The server\person who has infected your computer can do very nasty things like delete your windows software, turn on your webcam, see anything you type and of course hack anything stored on your computer as they have full access to your computer when turned on and connected to the internet.
Most Rats will be detected by your AntiVirus Software but hackers are always finding ways to bypass AntiVirus detection and their virus becomes what is called "FUD" fully undetectable.
How to stay safe 100% of the time
Since having only an anti-virus installed isn't enough to keep you secure from malicious hackers these days, here are tools that will keep you equipped against them.

"Sandboxie creates an isolated operating environment in which applications can be run or installed without permanently modifying the local system. This virtual environment allows for controlled testing of untrusted programs"
In other words, you can play any RSPS with an extra layer of protection if you have Sandboxie installed. When installed right-click on the client file you are about to run then click run with Sandboxie, Sandboxie will run it in its own environment and if anything suspicious happens you can terminate all programs running with Sandboxie
Once installed right-click on the file and press run sandboxed
This window will pop up make sure it's being run inside the default box and press ok:
Pressing ok will run the client and open a secondary window which display's what is being run \ executed, here is what it should look like:
if you hover over the top of the client and it turns yellow this means you have successfully run it through Sandboxie. if there is anything other than what is currently being displayed on the left of the picture in the Sandboxie window like runtime.exe, Then you are most likely running a malicious client. Head over to the Sandboxie icon right click it and press terminate all programs like so:
Then head over to defaultbox on top of terminate all programs and press delete contents
You have just saved yourself from being infected with a virus
