About
I'm Sivabalan Chandra Sekaran, a cybersecurity researcher focused on understanding how modern adversaries operate within enterprise environments — from initial access through persistence, credential abuse, and defense evasion.
My work spans offensive technique analysis, memory forensics, and translating research findings into actionable detection content. I believe the best security outcomes emerge when offensive research and defensive engineering collaborate through structured purple team exercises.
Previously, I've worked across threat research, incident response, and detection engineering roles. I publish technical write-ups, open-source tooling, and speak at security conferences on topics including Active Directory attacks, malware analysis, and Windows internals.
