Forensic hardware – Don’t just blindly trust it

September 2nd, 2014 No comments

I recently found two pictures which I took in the last 2 years, of the Logicube Forensic Dossier misbehaving. I decided to write this very short article to show these pictures. Since this seems to be a 6th(!) generation forensic solution I would not expect this behavior. The Logicube hardware is widely accepted as ‘forensically sound’, there seems to be some sort of blind trust in forensic hardware by forensic experts, while everything else is always disputed at great length.

Convert cheap 433Mhz sensors to KaKu/CoCo with an Arduino convertor

August 24th, 2014 2 comments

In the past 1,5 year I have been playing a bit with Home Automation (or Domotics / Domotica) systems. I initially bought the HomeWizard, but was pretty disappointed in it. When the HomeWizard domotica system was introduced I expected a lot of it, sadly enough it has not been as great as I hoped and I am currently moving over to another system.  One of the things that annoyed me of the HomeWizard is the inability to add other sensors to the setup which were not part of the supported hardware (which is pretty limited). I moved to the HomeWizard from a different (alarm) system which contained a lot of 433Mhz sensors which I could not hook up to the HomeWizard. Because I did not want to throw all these sensors away I built a middle-ware system with an Arduino and some code which can convert the non-supported codes in to HomeWizard supported codes (KaKu / CoCo style codes). The middle-ware receives a code and then translates that to a code which can be understood by the HomeWizard. Initially designed for usage with HomeWizard this same approach also worked with HomeSeer, Domotiga and Domoticz, which all did not support my sensors directly (most of them because of the usage of the RFXCOM).

Why online dating is one big scam

August 10th, 2014 No comments

This video shows one hundred fake profiles on the dating website Badoo. Most of these profiles were encountered in just a couple of days during normal usage of the website. Most of them are still active at the time of the release of this video (and long after that).

These profiles are probably a combination of scammers, catfish and people hiding behind other peoples pictures.
If something is too good to be true, it is probably too good to be true, also in the e-dating world.

Crypto hardware Plug-over attack

June 25th, 2012 5 comments

This article describes a vulnerability I found over two years ago in certain external USB and eSATA data carriers (hard drives, USB sticks) which use cryptography to help protect the data they carry. This vulnerability has been found during the evaluation of multiple data carriers of different manufacturers and it seems to be quite common. Since this vulnerability doesn’t seem device specific this paper has been written to be able to spread some knowledge and to warn the general public about it. All the manufacturers of the devices I tested which were vulnerable to this attack have been notified long ago. The vulnerability described in this paper has been named the ‘plug-over attack’.

Repair a broken HP LaserJet printer by baking it

October 18th, 2011 77 comments

After my HP printer died just after his warranty period I searched for a solution what to do to revive it. When reported to HP they wanted to charge €350 to repair the printer, which is around the same amount a new printer would cost, besides that I had to ship to whole bulky printer to them. When searching the internet for an alternative you will find a lot of people with the same problem using this printer series but not a lot of clear solutions.

This write-up will describe a way to repair the HP LaserJet M1522 series printer. While this idea is not new I wanted to create an easy to follow overview to repair this printer instead of a “just bake the formatter board”. I hope this write-up will be handy for some of the people out there with the same problem. While this write-up is focusing on the HP LaserJet M1522 MFP printer I would expect the same approach to work on other faulty hardware.

Hiding your data in plain sight – USB hardware hiding

September 29th, 2010 16 comments

—> The PDF version of this article can be found here.

This article will describe the possibility of hiding data in any kind of USB hardware. Even though USB data carriers come in various sizes and forms, which already sometimes makes them hard to recognize, this approach could even make it worse. Any USB device could be a data carrier and thus from a forensics point of view, any USB device should be taken into account when investigating a computer. Or, for example, from a company protection point of view, any USB device could be used to transport data out of the company.

The reason for writing this article is that the approach described in it has already been developed by me around 2007, while I was still working for the company Fox-IT. I presented part of this paper during a presentation I gave on the ENFSC 2007 congress, but since then I never made the full research completely public. I recently decided to redo my research and to work the idea out further. Since the information in this article is still current, I decided to spread the knowledge on it by publishing this article.

iPod dock adapter for the Motorola Droid/Milestone

Motorola Milestone iPod dock adapterManufacturers of electronic devices don’t seem to be able to get a global standard on docking connectors, resulting in that you usually end up buying a new dock for every electronic device you acquire. In the past I bought multiple iPod docks (also see my other article about bypassing the Apple video out protection on older docks here), but I own more devices than just the ones from Apple. My current mobile phone is a Motorola Milestone (or Droid if you are from the US), which of course does not fit on an iPod dock. Not willing to buy new docks I decided to build an adapter to enable me to use my iPod docks with my mobile phone. This article will describe step-by-step how I have built this dock adapter.

Because I am from Europe (the Netherlands to be precise) my Motorola device is named a Milestone, but the whole article of course is just as applicable to the Motorola Droid. For the ease of use I will just refer to the ‘Motorola Milestone’ in this article from now on.

Since all the information in this document is gathered from the internet or analyzed by myself it could be that there are some errors in this document, I am sorry if that is the case. Any opinion expressed in this document is solely my own.
