(ICS)² Chapter NL debate about voting machines

The Dutch chapter of (ICS)² asked me to tell about how the Dutch voting process could be easily hacked for the last 26 years, because the Dutch government outsourced vote counting tasks to computers:

Afterwards we discussed if the voting process should be executed on paper completely in the future. As it seems, around 50% of the security professionals that attended the debate thinks voting machines are still a good idea:

Discussion topic: “We have to keep voting with red pencil and paper”. People on the left agree; on the right disagrees.

I think this outcome is quite shocking! All the hacking experts I know are against voting machines, so my hypothesis is that technical security experts are against, and more process oriented security professionals vote for voting machines.

We need to fix this hacking knowledge and experience gap in our community (!)

Sputnik radio: Has Russia hacked the Brexit vote?

Moscow based Sputnik Radio interviewed me about the news that Russia might have tried to hack the Brexit election:


Update August 17, 2022
This interview (.mp3) was originally hosted on SoundCloud. I just found out they deleted this specific upload without notifying me about it. Guess giving an interview on Sputnik radio about a controversial topic is nowadays considered fake news. It seems that such uploads will be deleted by SoundCloud without researching the contents.

AFP: ‘Ditch computers to save democracy: ethical hacker’

See below for my in-depth interview to Jo Biddle from international news agency AFP:

Ditch computers to save democracy: ethical hacker

UTRECHT (NETHERLANDS) © ANP/AFP / by Jo Biddle
In an age of superfast computers and interconnected everything, the only sure way to protect the integrity of election results is to return to paper and pen.

That is the view of Sijmen Ruwhof, an ethical or “white hat” hacker, who last month revealed that the Dutch election’s commission computer software was riddled with vulnerabilities.

In a shock announcement just weeks before the March 15 elections — seen as a bellwether of the rise of far-right and populist parties across Europe — Dutch officials announced they were abandoning the computer system in use since 2009 to return to counting ballots by hand.

It was Ruwhof who discovered the problem. At the request of Dutch broadcaster RTL he spent just one evening examining the OSV software, developed for the Dutch government by a German company, via an online YouTube explanatory video, finding 25 weak points.

“It seemed to be completely insecure. I was quite shocked that we run our democracy, our election process based on very vulnerable software,” he told AFP. Continue reading

Cqure Quick Question: over (non)scoping bij pentests

Cqure nodigde me uit om te komen praten over de scoping van pentesten:

Cqure: “Sijmen Ruwhof van Secundity vertelt deze week in de Cqure Quick Question over (non) scoping bij pentests. Sijmen vertelt in deze video dat veel pentesten in Nederland van een zeer goed niveau zijn maar dat het verschil juist zit in een goede scoping, of een “non scoping” zoals Sijmen zelf noemt.”
