Hacking in the southern hemisphere

Last week I had the opportunity to visit https://en.wikipedia.org/wiki/S%C3%A3o_Paulo for the Hackers 2 Hackers Conference https://www.h2hc.com.br/en/


 

I was invited to give a keynote on UEFI security


This is only the 2nd public keynote I have given in my career. The first was back in 2018 https://www.osfc.io/2018/talks/keynote/. The latter treated open source, whereas this one predominately covered security but with a taste of open source weaved in.

I was humbled to be in the presence of so many impactful speakers https://www.h2hc.com.br/en/articles/speaker.html. A taste of other researcher talks can be found in the h2h mention at https://twitter.com/rcvalle/status/1735790682646712505, including the follow-up blog post

My topic 


 

visited some familiar themes but also included a snapshot of the latest work in mitigations https://github.com/vincentjzimmer/Documents/blob/master/H2H%20-%20Vincent%20Zimmer%20-%20The%20Story%20of%20UEFI%20(and%20its%20security%20mitigations).pdf.

I was impressed also with the BIOS hacking room where folks like

 


were writing BIOS, debuggers, and other low-level bits from scratch. One of the students brought out

As always, the 'hallway track' is the most engaging aspect of the conference. Therein I happened to meet some local firmware security engineers


 and signed a copy of the firmware security book https://link.springer.com/book/10.1007/978-1-4842-6106-4 that they were using at the university


too.

The city was an interesting study in contradictions. Immediately in front of the hotel I was treated to the scene

 


 And nearby in one direction



Whereas a short walk in the other direction yielded a modern mall with high-end stores


And of course long lay-overs and flights provide an opportunity to think of some of my favorite philosophers, such as Alan Watts.



Interesting stuff.
