The presentation I delivered in March 2015 at Rooted CON 2015 about the analysis and security weaknesses in the Android system update process is available in the DinoSec Lab, Android: Back to the Future, Two or Too?. The new version of the associated Burp Protobuf Decoder extension is available in the DinoSec GitHub repository.
The new presentation (contents are in Spanish) I delivered at the end of 2014 about the still vulnerable iOS update process (even if there is an associated CVE-2014-4383) are available in the DinoSec Lab, iOS: Back to the Future II. More details available in the related DinoSec Blog post.
The two presentations (both contents are in English) I delivered in 2014 at Rooted CON and Area41 about security vulnerabilities in the iOS update process are available in the DinoSec Lab, Rooted CON and Area41 respectively, together with (current or future) links to the videos. More details available in the related DinoSec Blog post.
