When you think of potential threats to electoral integrity, your mind conjures up all sorts of images. You start to imagine shadowy state actors toiling away from seedy basements in Moscow, or anarchic young hacktivists doing it for the lulz. In Belgium, they’ve got another potential foe to contend with: the actual polling agents themselves. It turns out that Belgium’s voting machines store a record of each vote on a USB stick. This drive uses a Linux-compatible filesystem — presumably because that’s what the voting machines themselves run. What happens when you shove one of the sticks into a computer running Windows? Well, the machine won’t recognize the stick and will tell you to format it with a compatible filesystem, like FAT32. And what happens when you do that? Well, you delete all the votes, that’s what.
A (since deleted) section on a Belgian government website warned against this very scenario, warning: “PAY ATTENTION! Do NOT format USB sticks!!”
“DO NOT FORMAT THE USB STICKS!,” it said. “Click on “Cancel.” If you format the USB stick, the data on it and thus the voting results are erased!!”
