Lead Android Researcher, Crowdstrike

Talk Title:

One SMALI Step For Man, One Giant Step For Researchers


The session will be a simple and short (in the limit of one day) introduction to Android reverse engineering, taking the student from zero to hero. No previous reversing knowledge is required and all of the tools will be provided in the form of a VM packed with goodies. The course will cover the basics of Android, APK structure, DEX file internals, and how this can be exploited in order to decompile and de-obfuscate malware.

In addition, hands-on exercises will be provided with fresh malware samples where the knowledge can be put to good use in extracting C2s and other interesting information.


Software developer turned rogue, went from developing apps for small businesses to 2M+ DAU Facebook games while keeping an eye for everything shiny and new. For a couple of years, I’ve shifted gears and started my career as a security researcher while speaking at various conferences (SAS, AVAR, PHDays) in my free time showcasing whatever random stuff I hacked. With a background in electronics engineering and various programming languages, I like to dismantle and hopefully put back whatever I get my hands on.
