Unusual Electronic Voting Machine Threat Model
Rats have destroyed dozens of electronic voting machines by eating the cables. It would have been a better story if the rats had zeroed out the machines after the votes had been cast but before they were counted, but it seems that they just ate the machines while they were in storage.
The EVMs had been stored in a pre-designated strong room that was located near a wholesale wheat market, where the rats had apparently made their home.
There’s a general thread running through security where high-tech replacements for low-tech systems have new and unexpected failures.
EDITED TO ADD (5/14): This article says it was only a potential threat, and one being addressed.
