Devi | Cybersecurity

Hello! I’m Devi Venkata Sai Prasad Annu, a cybersecurity professional with a strong foundation in security operations, digital forensics, and behavioral analysis. I hold a Master's degree in Cybersecurity from Pace University (GPA: 3.7) and a Bachelor's in IT from Vignan’s Lara Institute of Technology and Science.

My experience spans across SOC analysis, SIEM dashboards, phishing investigation, malware analysis, penetration testing, and forensic simulation. I’ve worked as a SOC Analyst Tier I and Cybersecurity Analyst Intern at Repo Builders, where I monitored threats using Splunk, ArcSight, Wireshark, and Nmap — and conducted vulnerability assessments and triage for real-world incidents.

I specialize in turning forensic data into behavioral insights. My capstone project, a Pre-Investigation Mobile Behavioral Analysis System, analyzes app usage, encrypted communications, flagged keywords, and GPS movements to predict and prevent crime.

🛠 Projects I've Worked On

• 🔍 Pre-Investigation Behavioral Analysis App — Android app to flag risky behavior patterns using on-device forensics. Includes GPS tracking, notification scanning, encrypted app monitoring, and red-flag alerts to authorities.
• 🧪 Mobile Forensic Toolkit — Simulation of multiple case studies (drug trafficking, stalking, financial fraud, insider threat, fake HR scam, social engineering). Includes log generation, CSV analysis, and SIEM visualization.
• 🛡️ OWASP Top 10 Analyzer — Web vulnerability scanner built to detect the OWASP Top 10 using Burp Suite, Python, and browser automation. Includes reporting and recommendations.
• 🔐 Secure File Storage in Cloud with Hybrid Cryptography — Combined AES and RSA encryption with key delivery over email. Focused on protecting sensitive files in public cloud environments.
• 💣 Petya Malware Analysis Report — Reverse engineered the Petya ransomware using Ghidra, OllyDbg, and IDA Pro. Included behavior analysis, payload review, and mitigation strategy using YARA rules and Splunk.
• 🌐 BGP Protocol Exploration & Attacks — Simulated BGP misconfigurations and route hijacking scenarios in lab environments using Cisco simulation tools and explored mitigation using prefix filtering and community attributes.

📜 Certifications

• ✅ CEH v11 – Certified Ethical Hacker (EC-Council)
• ✅ MTA – Security Fundamentals (Microsoft)
• ✅ NPTEL – Ethical Hacking (India MoE)
• ✅ LinkedIn Learning – CHFI Prep, Web App Security, OWASP, Threat Modeling, Excel 2016

🎯 Career Goal

I’m currently seeking full-time opportunities in security operations, digital forensics, penetration testing, or behavioral threat analysis. I aim to join a security-driven team where I can build detection systems, investigate threats, and develop scalable forensic solutions.
