Windows 10: I have been hacked thru old MPC-HC on Windows 10

Hello,

I had a strange situation.I'm using newest windows 10 pro 19042.

I was watching drm-free mp4 offline file from HDD downloaded from big TV broadcaster polsatsport.pl. I paused my clip on MPC-HC 1.7.13 discontinued in 2017 ,turn off monitor and left for 15 minutes.
Other open apps was waterfox with few tabs and newest total commander 9.51.
When I back MPC-HC was gone and site of MPC-HC fork was opened in new waterfox's tabhttps://github.com/clsid2/mpc-hc/releases.
I bet that link was opened by MPC-HC ,but I believe this link doesn't exist in MPC-HC 1.7.13 code.
WebUI was disabled by default and i never used it in MPC-HC.
I'm connected via lan to pretty new fibre router by huawei.

I checked Event viewer carefully including TerminalServices-LocalSesionManager and RemoteConnectionManager and found nothing.
My windows defender logs was set to disabled and I'm using windows antivirus only.


My questions are :
Where to find evidences ? How deep this hack can be ? Is it possible my logins.json or other files was stolen using mpc-hc webui or other method ?

Regards,
Thanks for answers

:)

 

even tho I have installed mpc-hc, its not available as default choice ..why ?

What is happening, is that Win 10 is picking up not the executable desktop MPC -HC , but rather the "Uninstall" that comes with MPC-HC. ...so, what happens is that when I do as you recommend,, and click on the icon, in the SETTINGS list, I get an "uninstall
MPC-HC" query, rather than Win10 opening the player screen ...Frustrated.

To me, the simplest thing for MS to have done is INCLUDE all the popular free-source vid players (eg. MPC-HC, VLC..) in its OEM "store".

Your response has been timely and though not solving the problem, has moved the solution process forward. Baby steps.

MPC-BE is a fork created and actively maintained by the Russian team of aleksoid/alexins/v0lt

It contains additional features and bug fixes.

That´s not correct. MPC-HC is still being developed. I use and regularly update the K-Lite codecs, and MPC-HC is included with them. Now I am on v. 1.9.2.6.
