Hopefully they reviewed security camera footage (if there were any, the reporter didn’t see any) and verified software and operating system checksums on all unsecured machines.

If a bunch of high value targets are left exposed like this they should really immediately pivot to Digital Forensics and Incident Response. If they didn’t, I would imagine it could put any votes tabulated by those unsecured machines as suspect and maybe even thrown out in court. Disclaimer, IANAL, I’m a humble IT Security pede.
