No need to wait. There will be no stable patch from vi-rus coz the he/she can't beat the time bomb protection.
I have looked at his/her crack. He missed 2 files which are also need to be patched.
Since version 8.2.0 if I remembered correctly, Synology added more protection.
If you record in MPEG, his/her crack will be caught by the new protection, but not if recording is in h264 or h265.
If the camera has sound, like baby cam, his/her crack will also be caught by the new protection.
So just use the 8.0.3 crack.
