haldermanYou may have read at NYMag that I’ve been in discussions with the Clinton campaign about whether it might wish to seek recounts in critical states. That article, which includes somebody else’s description of my views, incorrectly describes the reasons manually checking ballots is an essential security safeguard (and includes some incorrect numbers, to boot). Let me set the record straight about what I and other leading election security experts have actually been saying to the campaign and everyone else who’s willing to listen. 

How might a foreign government hack America’s voting machines to change the outcome of a presidential election? Here’s one possible scenario. First, the attackers would probe election offices well in advance in order to find ways to break into their computers. Closer to the election, when it was clear from polling data which states would have close electoral margins, the attackers might spread malware into voting machines in some of these states, rigging the machines to shift a few percent of the vote to favor their desired candidate. This malware would likely be designed to remain inactive during pre-election tests, do its dirty business during the election, then erase itself when the polls close. A skilled attacker’s work might leave no visible signs — though the country might be surprised when results in several close states were off from pre-election polls.

Could anyone be brazen enough to try such an attack? A few years ago, I might have said that sounds like science fiction, but 2016 has seen unprecedented cyberattacks aimed at interfering with the election. This summer, attackers broke into the email system of the Democratic National Committee and, separately, into the email account of John Podesta, Hillary Clinton’s campaign chairman, and leaked private messages. Attackers infiltrated the voter registration systems of two states, Illinois and Arizona, and stole voter data. And there’s evidence that hackers attempted to breach election offices in several other states.

In all these cases, Federal agencies publicly asserted that senior officials in the Russian government commissioned these attacks. Russia has sophisticated cyber-offensive capabilities, and has shown a willingness to use them to hack elections. In 2014, during the presidential election in Ukraine, attackers linked to Russia sabotaged the country’s vote-counting infrastructure and, according to published reports, Ukrainian officials succeeded only at the last minute in defusing vote-stealing malware that was primed to cause the wrong winner to be announced. Russia is not the only country with the ability to pull off such an attack on American systems — most of the world’s military powers now have sophisticated cyberwarfare capabilities. Read More

Verified Voting Blog: Hacking the D.C. Internet Voting Pilot

This article was posted at Ed Felten’s “Freedom to Tinker” blog and is re-posted with permission.

The District of Columbia is conducting a pilot project to allow overseas and military voters to download and return absentee ballots over the Internet. Before opening the system to real voters, D.C. has been holding a test period in which they’ve invited the public to evaluate the system’s security and usability. This is exactly the kind of open, public testing that many of us in the e-voting security community — including me — have been encouraging vendors and municipalities to conduct. So I was glad to participate, even though the test was launched with only three days’ notice. I assembled a team from the University of Michigan, including my PhD students, Eric Wustrow and Scott Wolchok, and Dawn Isabel, a member of the University of Michigan technical staff. Within 36 hours of the system going live, our team had found and exploited a vulnerability that gave us almost total control of the server software, including the ability to change votes and reveal voters’ secret ballots. In this post, I’ll describe what we did, how we did it, and what it means for Internet voting. Read More
