onsite machines often use removable media for data transfer (and software update)
80% of the market is two vendors, 95% in top 3 vendors
15-year unpatched windows 2000. LOLSOB!

Wireless Odyssey or why is the federal government permitting devices with wireless networking capability in federally certified voting machines?

she's on a huge rant against having any wireless connectivity possibility in election devices ... and that's going to get harder as more and more things have it by default. e.g. Couldn't build with a Rasberry Pi or any common tablet. This will increase expenses!
I disagree. Software disabling of radios is enough. Nothing can turn them on from the outside. If you can get in and turn them on to enable a hack, you have already hacked the device.

Are Barcodes on Ballots Bad?

[my hot take before listening: YES]
ES&S 2011-2014 introduction of assistive voting machine
ES&S, Dominion, Unisyn
ES&S Code128-C - 6 digit candidate identifier which maps to timing mark grid bubble coordinate
vote in barcode and vote in text
Dominion QR-code (or multiple QR codes)
QR-code binary mode, densely packed
vote bubbles are a bit stream, bit per bubble
HMAC signature
Unisyn
receipt tape
custom barcode ('compressed' vote bubble grid)
also some Code128
barcodes ARE FUD PRONE!
and unneccessary
Dominion switched from barcode to marking bubbles at Colorado request

a surprisingly small number of ballots can be sampled to validate an election. This could be a source of FUD.

For only 300 euros they were able to buy fake engagement on social media platforms and drive up their message.

twitter best at anti-abuse
instagram much easier to manipulate than fb
tiktok is the newb, easiest to manipulate, might be getting better
New Hampshire SB43 Forensic Audit

Windham, NH election Audit May-June 2020
Many systems with published vulnerabilities from 2007 are still in use in 2020.
Many NH elections are hand counted! (smaller towns)
300 vote discrepancy between machine and hand recount (out of ~10,000 total votes). Weird partisan pattern in that gap. Race was 8 candidates, pick 4.
AccuVote optical scan (very old). Totally weird 80186 embedded system. ~143 kB for kernel and app. (security through obsolescence?)
two hand counts agree, 4 different machines get varying results.
In a few races, machines consistently under-recognize votes
(Some scanners have bulit in 'features' like punch-hole-removal that can screw with ballot scanning!)
mailing out vote-by-mail ballots through a paper folding machine
folds across bubbles cause misread
ballots re-counted 6 months later counted better because they had been flat in stacks
'offset printing powder' fouled a ballot scanning machine
extensive check of tech hacking found none; just physical oops screwups.
