Projects
Avala — Exploit Development Framework for Cybersecurity Competitionsgithub ↗website ↗
Personal project
- Built and maintained a Python framework for developing and deploying exploits in attack/defense (A/D) competitions with the goal of taking the technical burden off the team players. Players can rapidly develop, test, run exploits on their own machines and monitor all the attacks in real-time through a centralized web dashboard.
- The development of the tool was heavily influenced by the practical experiences and valuable insights gathered by the Serbian National ECSC Team who utilized the tool in multiple A/D competitions.
