Vishalkumar Sivakumar

Cybersecurity undergraduate (Amrita Vishwa Vidyapeetham) with hands-on experience in vulnerability assessment, phishing detection, and ML-driven threat detection — applied across a virtual internship and 4 independent security projects. Currently advancing practical skills through SOC analyst labs on TryHackMe, covering SIEM, alert triage, and network traffic analysis. Seeking a cybersecurity internship where I can apply hands-on skills in threat detection, vulnerability assessment, and ML-based security systems to solve real-world security challenges.

Cybersecurity Intern at Thiranex IT Solutions (2026 – Present)

• Reduced simulated attack surface by scanning 100+ open ports and services across target hosts by building a Python + Nmap based vulnerability scanner that automated host discovery and service enumeration.
• Improved password policy compliance by enforcing entropy-based strength rules (length, character diversity, pattern detection) by developing a password strength analyzer that flagged weak credentials before storage.
• Achieved 87% accuracy in phishing email classification across a labeled dataset of 2,000+ samples by engineering NLP-based features (URL patterns, sender spoofing, urgency cues) and training a Random Forest model.
• Eliminated SQL injection and credential stuffing vectors in a login workflow by implementing SHA-256 password hashing, prepared statements, and session-based access control using Java and MySQL.
