I printed a 3D box for my bettercap arsenal and I liked it

Looking at the title you might think that it’s Katy Perry new hit… It isn’t… I’m sorry…

One of my favourite tools when doing security assessments is bettercap. Its like “one tool to rule them all”. With that in mind, I needed something to carry my bettercap arsenal when going to a client. Using my self-taunted 3D skills (btw n00b level) I decided to design my own box.

I needed something to pack the following:

The first version I encounter some issues. It was too big; alfa card was a bit tight; lid didn’t closed correctly and not very appealing.

So I started working on my second version which I would reduce a bit by putting the slot for the two antennas (Alfa card and the CrazyRadio) and modify the BLE dongle slot to also reduce some space. Added 4 pinouts to better close the lid.

I was getting close of what I needed neitherless I wanted more specially because I had an hard time taking the antennas and the BLE dongle. Also, the pinouts were not a good option to accomodate the lid. So I decided to add a few things:

  • Small cuts to improve the removal of the antennas and the BLE dongle
  • New slot to put whatever I needed – you never know…
  • New lid that just slides into the box

And what about the lid? Besides helping to open – creating some friction –  its leet 🙂

If you are interested in printing it, I uploaded it to Thingiverse and feel free to ping me on Twitter for suggestions or modifications.

Have fun!

Our DEF CON 28 day was a blast

Our DEF CON 28 day was a blast

4 portuguese security researchers presented at DEF CON this year. I’m sure that was a record 🙂

  • Paulo Silva and I with API (in)Security TOP 10: Guided tour to the Wild Wild World of APIs (which you can check the recording on Youtube).
  • Pedro Umbelino and João Morais with Android Bug Foraging (check the talk on Youtube)

With this in our mind, we gathered together at Char49 meeting room and saw it together… with drinks and pizza.

The fun was just starting. On Pedro and João talk, they included a never shown video  before regarding Google Camera issue which included myself being a victim of this vulnerability.

We even did the CONs tradition of “Shoot the N00b” for first time speakers – drink a shot before the talk. The poison was Pedro Umbelinos’ homemade firewater. I would lie if I would say that it didn’t hurt going down 🙂

In the end we had lot of fun and I hop enext year we can be together again giving a talk at DEF CON. Who knows?

PS: A new entry on my bucket list can now be checked – be a speaker at DEF CON.
