Collecting Actionable Threat Intelligence from Digital Underground

Master thesis project done together with University of Trento and Auxilium Cyber Security GmbH. Goal of the thesis was to research existing deepnet and darknet communities and to devise a methodology which would allow extraction of useful threat intelligence connected to malware, exploits and related services and products. Several underground resources had been researched out of which two selected closed communities were infiltrated. Subsequently, tool for automated covert data collection from those resources was developed. Tool for analyzing the collected data was also proposed as part of the thesis and extracted threat intelligence is currently being used by one of the Auxilium products.

Russian Covert Activities in Cyber Space

Android OS adjustments (bachelor thesis - in Czech language)

Theoretical part covers the architecture of Android operating system and elaborates on what modifications are feasible with/without the availability of source codes. Practical part consists of development of system update for Ainol Novo 7 Crystal tablet and research on how to apply this update over SSH. OS Android source codes for this specific tablet model have never been released and update was thus develop by means of reverse engineering build in the tablet and changing its Java bytecode. Update optimized the behavior of ethernet interface. It was deployed in tablets which are part of Ackee's “Domovník”​ (home doorbell system) hardware solution and proved to be fully functional. More information on can be found here.
