Last week, we noted that an attempt to let hackers crack e-voting machines in Brazil failed, but Slashdot points out that someone did use some Van Eck phreaking to figure out who people voted for. While that's not quite the same as hacking the results of an election, it could lead to questions about privacy and how anonymous voting really is. Of course, to some extent, this has always been a risk with e-voting systems, but it hasn't received that much attention.
