Princeton study and video: how to hack a Diebold machine

Video here.  Executive summary here.  Full research paper here.

The main findings of our study are:
  1. Malicious software running on a single voting machine can steal votes with little if any risk of detection. The malicious software can modify all of the records, audit logs, and counters kept by the voting machine, so that even careful forensic examination of these records will find nothing amiss. We have constructed demonstration software that carries out this vote-stealing attack.
  2. Anyone who has physical access to a voting machine, or to a memory card that will later be inserted into a machine, can install said malicious software using a simple method that takes as little as one minute. In practice, poll workers and others often have unsupervised access to the machines.
  3. AccuVote-TS machines are susceptible to voting-machine viruses
