Greetings,

Sorry i am new to using Kali OS, i am taking some help from a friend who suggested that it could be a possible hack.

I had a concern regarding my Kali Installation which was input into my mind by the same friend of mine who has been helping me use this to some extent. Sorry i am naive in this OS. The concern is to validate if my OS is hacked or not. I do have reasons to believe that because I am having this problem of a sticky mouse on the browser windows for the past few days. which led me to update the setup a couple of times.

The command "sudo apt-get update" was run. This update seems to be using some of the sources which does not seem to be from the original source files in the configuration ( as per what i understand from my friend). IN particular the source of http://ftp.yzu.edu.tw/Linux/kali


In my understanding all the sources should be *kali.org. Not sure why is this listed while updates. Not to mention that there are some events which does make me believe that this could be a possible hacked source. Please do suggest as to if there needs to be done something to rectify this? If any more info is needed then please advise.


Some of the references are stated below. sI will check back again tomorrow appreciate your input. Thank you
