About Me

I will graduate from the University of Maryland Spring 2023. During my time there, I was an Honors College student and complete the Advanced Cybersecurity Experience for Students (ACES) living-learning program, as well as the ACES Cybersecurity Minor. Throughout these programs I have discovered a love for cybersecurity, and have been in the Scholarship for Service program, with a job working on offensive cybersecurity software development with the US government.

Projects

Network Traffic Analysis

Created visualizations in R and Python to determine trends from NASA’s HTTP traffic Apache logs.

Solved the 2009 VAST challenge – Badge and Network traffic, with data visualization and analysis in Python, attempting to identify unusual activity by looking at IP traffic trends by time, destination IP frequencies, packet size, and number of requests by user, comparing these findings with the data from another data table about the authentication times for employees, alongside two other students.

Reverse Engineering

Reverse engineering C code from x86_64 AVR assembly decompiled from binary files as a static assembly file, dynamically during runtimes with the GDB debugger, and with Ghidra with function names stripped, to determine the function of the binary and potential places for exploitation within GDB or with a buffer overflow.

Reverse engineered a small C++ application with Ghidra.

Vulnerability Exploitation

Identified a buffer overflow within an existing system and prepared shellcode and its proper placement, with the goal of creating evidence of the vulnerability’s existence and potential for malicious exploitation.
