Thread 1/7 WHY WE NEED #AUDITS. Professor Andrew Appel breaks down the #myth that someone can't #hack a #VotingMachine if it's not connected to the #Internet. freedom-to-tinker.com/2018/02/22/are… #PaperBallots #AuditTheVote
Thread 2/7 "The ES&S model #DS200 #optical-scan voting machine has a #cellphone modem that it uses to upload #election-night results from the #voting machine to the “county central” canvassing #computer." #PaperBallots #AuditTheVote 
Thread 3/7 "The voting machine calls the county-central computer using its cell-phone modem... this connects ... to a cell tower ... near the canvassing computer." #PaperBallots #AuditTheVote
Thread 4/7 "Each border router runs ... millions of lines of software; as such it is subject to bugs and vulnerabilities. If a hacker finds one of these vulnerabilities, he can modify messages as they transit the .. network" #PaperBallots #AuditTheVote
Thread 5/7 "Even easier than hacking through router bugs is just setting up an mposter cell-phone “tower” near the voting machine; one commonly used brand of these, used by many police departments, is called “Stingray.” #PaperBallots #AuditTheVote
Thread 6/7 "S/he will do better to put his Stingray near the county-central canvassing computer, so s/he can hack all the voting machines in the county, not just one near his Stingray." #PaperBallots #AuditTheVote
Thread 7/7 "So, in summary: phone calls are not unconnected to the Internet; the hacking of phone calls is easy (police departments with #Stingray devices do it all the time); and even between the cell-towers (or land-line stations), your calls go over parts of the Internet."
