BSides Lisbon and SECUINSIDE 2015 presentations

I guess my goal for the remaining 2015 of not doing any presentations will not happen. Two weeks ago I presented at BSides Lisbon 2015 and last week at SECUINSIDE 2015. I’m very happy to see BSides Lisbon returning after the first edition in 2013. Congrats to Bruno, Tiago, and the rest of the team for making it happen. It’s still a small conference but I’m glad they are making it happen, and I will always do my best to help the Portuguese scene going forward. [Read More]

Revisiting Mac OS X Kernel Rootkits Phrack article is finally out!

Enjoy it at Phrack. It’s finally out. It feels a bit old and it is indeed a bit old but still a good paper (or at least I tried to make it that way). The supplied code is for an older version of that rootkit. For example it still has dependencies on importing task, proc and other kernel private structures. The updated version solves all required offsets so it supports easily new and old OS X versions. [Read More]

SyScan360 Beijing slides

Eight days and 10 flights later I am back from SyScan360 in Beijing. It was my first visit to China and I had lots of fun observing many things that I only “knew” from reading. The scale and dimension of everything in Beijing is quite a surprise. No wonder why every Western company wants to be there. We had great food and an awesome visit to the Great Wall. A big thank you to the boys and girls from the organization for all their hard work and dedication. [Read More]

HiTCON 2013 slides

Taipei is definitely one of my favourite cities in the world! I love its “infinite” amount of small shops, in particular at night when lights are on. Streets look so beautiful and busy. Everyone is very friendly and respectful, and most important, I feel very safe. And the food is awesome (thank you Thomas!). I really love it! If you like Asia, Taiwan is a must visit. The only problem is language – English is not widely spoken. [Read More]

HITCON 2012 Review and slides

After more than 30h inside planes and airports, I’m finally back home! Asia 2012 tour is over. HITCON was really great and well organized. It was bigger than I expected, with lots of curious and cool people. Went in the mood and took many pictures with everyone – there goes my anonymity! My speaking slot was after lunch, which is a tough one. I could only spot half a dozen sleeping so I might have done a good job. [Read More]

Secuinside 2012 Review and Slides

After 27h flying around the world and hanging at airports I’m finally back home. Secuinside 2012 in Seoul was fantastic! The organization was really great and most of all, exceptionally friendly and awesome hosts. There are minor details to work at for next year but these guys had a very short time frame to organize this one. Lots of hard work behind it! They definitely have the talent required to take it to the next step. [Read More]

Added a new page, Papers & Presentations

I have added a new page called Papers that contains papers & presentations related to OS X and iOS (reversing, hacking, exploitation) that I have floating around in my harddisks.
It’s a work in progress since I have stuff spreaded everywhere!

Please be gentle with any mirroring efforts 😉.

Enjoy,
fG!

News...

A peak of work and vacations results in no reversing for the past weeks :-(. I had some advances on Little Snitch and I will publish them soon. Blackhat USA 2008 had some interesting stuff related to Mac OS X. And older paper related to DTrace (I really need to install Leopard to start messing around with DTrace) and another about Mac OS X Rootkits (very interesting!): RE:Trace – Applied Reverse Engineering on OS X [Read More]
