Summary
Sai Ruppa is a Staff Security Researcher with six years of hands-on experience in threat research, application security, and incident response, currently contributing to Unit 42 at Palo Alto Networks. A Carnegie Mellon Information Security graduate student and former TA for Mobile & IoT Security, he blends academic rigor with practical tooling and adversary-tracking expertise. His prior work includes building a real-time Mirai botnet tracker that infiltrated 20+ botnets and gathered metadata on over 90,000 victims without participating in attacks, and implementing large-scale PAM and red-team automation for enterprise clients. He has a track record of offensive and defensive impact—from developing dark-web crawlers used in Delhi Police investigations to uncovering 50+ critical vulnerabilities in client environments—demonstrating a balance of ethical hacking and measurable risk reduction. Based in Mountain View, Sai pairs deep malware/IoT insight with automation-first approaches to scale detection and response, and he often surfaces non-obvious attacker artifacts that improve long-term threat hunting.
