Real-world cybersecurity challenges, penetration testing engagements, and security solutions I've developed and implemented.
Comprehensive external and internal penetration test for a Fortune 500 financial institution. Discovered 23 critical vulnerabilities including privilege escalation chains, lateral movement paths, and domain controller compromise.
Designed and executed a multi-vector social engineering campaign targeting 500+ employees. Achieved 15% success rate with phishing, vishing, and physical security bypass techniques.
Deployed Splunk SIEM across 5,000+ endpoints, created 150+ custom detection rules, and reduced false positive rate by 85%. Improved incident response time from 4 hours to 15 minutes.
Built automated incident response playbooks using Python and SOAR platform. Reduced containment time by 70% and created 25+ automated response workflows for common attack patterns.
Comprehensive security assessment of a high-traffic e-commerce platform processing $50M+ annually. Identified and remediated 12 critical vulnerabilities including payment processing flaws and session management issues.
Developed comprehensive API security testing framework for microservices architecture. Created automated testing suite covering OWASP API Top 10 and custom business logic vulnerabilities.
Conducted comprehensive security analysis of 50+ smart home devices from major manufacturers. Discovered 8 zero-day vulnerabilities in popular IoT platforms including Ring, Nest, and Alexa devices. Published findings at DEF CON 2023.
Built isolated malware analysis environment and developed automated analysis tools. Analyzed 1,000+ samples, created YARA rules, and contributed to threat intelligence feeds used by 50+ organizations.
Developed comprehensive security automation toolkit with 15+ tools for vulnerability scanning, log analysis, and threat hunting. Used by 200+ security professionals and integrated into CI/CD pipelines.
Built specialized vulnerability scanner for web applications with custom detection engines. Scans 10,000+ URLs in under 2 hours with 95% accuracy rate and minimal false positives.
Comprehensive security assessment across AWS, Azure, and GCP environments. Identified 45 misconfigurations, implemented least-privilege access, and established cloud security governance framework.
