OK, this is two year old news:
The Washington Post ran an article two years ago when University of Michigan researchers hacked (by invitation) the DC Elections voting trial. For the scholarly article, see Attacking the Washington, D.C. Internet Voting System, in Proceedings 16th Conference on Financial Cryptography & Data Security.
What makes it new news? Was it that the election was for Bender? That captures people’s imaginations. However, the relevance for us at the GCSC is they also captured video of the administrators. See Hack reaction caught on pwned webcams from SC Magazine.
