  • [11/24/2020] Students in my research group hacked Dominion Imagecast Precinct in DEF CON Voting Village in 2019. There were many vulnerabilities, however, all demonstrated hacking requires physical access to the machine, and thereby, it’s hard to scale. So I do not believe that the election could be rigged by the vulnerabilities that our students reported.
