She did reveal a weakness. But, it was disclosed. Essentially, Dominion doesn’t build their own voting machines. They rebrand HPE or Dell servers (I forget), then reimage them. However, there is system board software called iLO or iDRAC that allows you to access the machine remotely when the OS is inaccessible for some reason.
There are two ways to disable this. (This is literally disclosed in the setup manual.) 1.) you don’t plug an ethernet cable into that port or 2.) the recommendation, disable the iLO/iDRAC in the BIOS.
Dominion is kind of lame for doing this, but if the user follows the directions, it’s removed as a “vulnerability”.
The person who leaked it is obviously an idiot. The “super spy” move of turning the cameras off was pure genius.
