One life.
Two worlds.

I grew up in Chennai speaking Tamil, dreaming big. A Master's took me to Melbourne where I built a career, a family, and a home. Then the cloud called louder — and AWS brought me to San Francisco.

Seventeen years in cybersecurity means I've seen every threat wave — from network perimeters to cloud to now the agentic AI frontier. I don't just defend systems. I think about where the next blind spot is before it becomes a breach.

" Security isn't a product. It's a posture. And in 2026, that posture must account for autonomous AI agents. "

The Agentic AI Kill Chain

Building on MITRE ATLAS and OWASP LLM Top 10, this framework maps the attack lifecycle specific to autonomous agent systems — from reconnaissance to persistence.

$ kill_chain.stages:
RECON → INJECT → HIJACK → ESCALATE → EXFILTRATE → PERSIST
01
RECON
Probe Agent Capabilities
Map tools, MCP servers, permissions, and behavioral boundaries. Agent recon maps capability topology — not network topology.
extends: ATLAS recon for ML models → agent tool and permission enumeration
02
INJECT
Deliver the Payload
Prompt injection, tool-response poisoning, MCP schema injection, context window displacement. The goal: change what the agent does, not just what it says.
extends: OWASP prompt injection → tool-response and MCP protocol injection
03
HIJACK
Override Agent Behavior
Goal substitution, instruction override, reasoning chain manipulation. The agent continues operating autonomously — toward the attacker's objectives.
extends: OWASP excessive agency → autonomous decision chain hijacking
04
ESCALATE
Expand Access
Abuse tool permissions, chain multi-agent delegation, confused deputy attacks. Agents trust other agents — exploit the trust model.
extends: ATLAS privilege escalation → multi-agent delegation chains
05
EXFILTRATE
Extract Value
The agent is the exfiltration channel. Legitimate tool access, legitimate output channels. Exfiltration looks like normal agent behavior.
extends: ATLAS tool exfiltration → cross-session memory leakage patterns
06
PERSIST
Maintain Access
Poison memory, inject into CLAUDE.md and config files, backdoor skills. The agent itself becomes the persistence mechanism.
extends: ATLAS memory manipulation → config, skill, and ecosystem persistence

Builds on MITRE ATLAS v2026 (16 tactics, 84 techniques), OWASP LLM Top 10 v2.0, and Lockheed Martin Cyber Kill Chain. Extends these frameworks for autonomous agent systems.
