Original GitHub issue: https://github.com/quasar/Quasar/issues/1243

Yesterday i had an incident. Someone on a VPN and a virtual machine with a fake desktop and "Client-builder.exe" connected to my quasar listener with me only sharing it on a small group chat of tech savvy friends and a github page trying to get my friends to download and test so i can see if i port forwarded correctly.

What is this guy trying to do on a VM and with an italian VPN with a fake desktop trying to connect to my listener? My brother thinks he was trying to reverse it and try and get me ratted but i thought there might be another reason why.

I'm not sure why you're opening an issue for this. You shared your client.exe, someone opened it and it connected to your server. I'm not aware of any ongoing exploits targeted at the Quasar server in latest version v1.4.1.

Did i mention that i didnt share it to anyone that would make a whole vm and reverse the connection? My friends have confirmed they havent done this and a person who I didnt share it to somehow found the file..

it's probably that your friends are lying, or your computer is compromised and someone got the file somehow. as far as i know, it is impossible for quasar to grow legs and get on another computer.
