Security Researcher

ACI Limited • ZZP

Feb 2025 - Jul 2025 • 5 mos

As a Security Researcher at ACI Limited, I was responsible for conducting Web Application Penetration Testing (WAPT) and Vulnerability Assessments to identify and analyze security weaknesses across enterprise applications and internal systems. My work involved performing manual security testing using attacker-driven methodologies and OWASP Top 10 standards to detect vulnerabilities such as SQL Injection (SQLi), Cross-Site Scripting (XSS), Broken Authentication, Access Control issues, and Security Misconfigurations. I regularly utilized tools including Burp Suite, Nmap, Nessus, and Metasploit to assess security posture, validate vulnerabilities, and support remediation efforts. I also collaborated with development and IT teams to provide technical recommendations and improve overall cybersecurity resilience within the organization.
