• Reversing malware USB drives in Gothenburg

    This Wednesday reports about USB-drives with malicious code being found in the area Lindholmen in Gothenburg, spread in Swedish media. It was reported by, among others, IDG, Expressen, SVT and even far-right sites such as Nordfront. This quickly spread in social media and all kinds of wild theories started to appear including industrial espionage and Russian hackers using "military-grade encryption". All of this, of course, without any kind of evidence to back it up. Being a strong opponent to the FUD that is very commonly spread in security related events I sought to dig deeper into this.

  • SEC-T 2016 Talk: SMT in RE

    Today at around 16:00 I'm doing a lightning talk at the SEC-T security conference titled "SMT in reverse engineering, for dummies". A stream to the talk should be available on YouTube where you hopefully will be able to see the talk. It will probably also be available online afterwards. I will update this post with a link.

    Unfortunately, the SEC-T arrangers lost all the recordings due to technical problems. Fortunately, I re-recorded my talk and put it on YouTube.

    In the talk I'm referring to some scripts I have written. You can also download the slides as a PDF.

  • Boldport Club project 5: The Tap

    I have long had the wish to learn more about hardware and DIY electronics but never really found the right motivator or opportunity, that is until now. It was the day following "brexit" I saw a tweet retweeted by Travis Goodspeed promoting the Boldport Club (with a 20% discount). The Boldport Club is kind of like an old school book club which sent you a monthly book, only they send you a monthly DIY electronics kit to assemble. I thought this would be the perfect way to finally get into some hardware so I signed up for three months to try it out. In this post I will guide you through the process of assembling the first project: The Tap.
