Tyrese Iulio

Cybersecurity practitioner with a B.S. in Cyber Operations and a CompTIA Security+ certification, specializing in offensive security techniques, detection engineering, and technical documentation. Experienced in writing security-relevant code in Python and PowerShell, navigating complex lab codebases, and evaluating system vulnerabilities. Adept at breaking down advanced threat analyses into clear, actionable technical explanations. Flexible hard worker ready to learn and contribute to team success.

• Detection Engineering & Threat Analysis (Suricata IDS), Configured and deployed a Suricata Intrusion Detection System to monitor web server traffic in an Ubuntu environment., Authored, tested, and patched custom detection rulesets specifically targeting unauthorized file uploads and data exfiltration techniques., Evaluated security alerts and traffic logs to tune out false positives, demonstrating a strong understanding of how systems reason about real-world threats.
• Offensive Security & Malware Simulation Tooling, Designed and wrote a custom file-stealing payload from scratch using Python and PowerShell to simulate targeted data exfiltration., Navigated complex code logic to implement multi-stage execution and obfuscation techniques designed to bypass signature-based detection., Documented the codebase and attack lifecycle to provide a clear technical explanation of the exploit chain and corresponding host-level defenses.
• Penetration Testing & Vulnerability Assessment (ICS), Executed an offensive security assessment on an Industrial Control System (Modbus-based PLC) using Hack The Box environments., Solved technical security problems by enumerating network assets, identifying vulnerabilities in industrial protocols, and manipulating logic controllers to retrieve flags., Evaluated the validity and accuracy of potential attack vectors within operational technology (OT) networks.
• Technical Writing & Advanced Threat Evaluation, Researched, authored, and presented an advanced technical evaluation of kernel-level drivers and Direct Memory Access (DMA) vulnerabilities., Analyzed state-of-the-art anti-cheat mechanisms, documenting how threat actors design bypasses at the hardware level., Translated complex, low-level system interactions into clear, well-structured technical documentation for university-level peer review.
