Project

  • APT Discovery using OSINT and Network & System Logs
    • Integrated Open-source intelligence, Cyber threat intelligence, and MITRE ATT&CK framework into a cyber threat knowledge base, and developed neural network architectures to analyze and detect APT attacks in a multi-host environment.
    • Aligned the observed evidence to adversary lifecycle and correlated the relation between the detected 

      attacks and known attackers.
