"The nation’s top voting-machine maker has admitted installing remote-access software on election-management systems that it sold over a period of six years, in what one U.S. senator described as 'the worst decision for security short of leaving ballot boxes on a Moscow street corner.'... Election-management systems are not the voting terminals used to cast ballots: They stay in county election offices and contain software used to program the voting machines and count up final results from the voting machines. The remote-access software created an opportunity for hackers to breach the machines. Election-management systems and voting machines are supposed to be disconnected from the internet and from any other systems that are connected to the internet for security reasons. ES&S customers who had pcAnywhere installed also had modems on their election-management systems so ES&S technicians could dial into the systems and use the software to troubleshoot." https://www.thedailybeast.com/voting-machine-vendor-put-remote-access-software-on-systems-sold-to-us
Well. The cat finally gets let out of the bag. Always thought those machines were easily tampered with by anyone with just the right know how.
