Computer Engineer · AI Security Researcher · Pentester

I work at the intersection of agentic AI and offensive security, building AI agents that attack and defend systems and auditing AI systems for vulnerabilities. My current focus:

  • Offensive AI agents: LLM-powered multi-agent frameworks for recon, exploitation, and post-exploitation automation (LangGraph, MCP, A2A).
  • Defensive AI agents: Agentic pipelines for threat triage, incident response, investigation assistance, and post-incident documentation.
  • AI system security: Attacking LLMs and agentic pipelines in production: prompt injection, jailbreaking, RAG exfiltration, tool poisoning, adversarial ML.

Projects

AI System Auditing

Security assessments of production AI deployments: LLM-powered platforms, agentic pipelines, and systems with broad tool/connector surfaces. Findings reported using OWASP API Security taxonomy and CVSS 3.1 scoring.

Smart Contract Auditing Agent

LangGraph multi-agent system for automated Solidity auditing, targeting bug bounty platforms (Immunefi, Code4rena, Sherlock).

Attacking LLMs & Agentic Pipelines

  • Prompt injection (direct & indirect, including via MCP channels)
  • Jailbreaking and alignment evasion
  • Tool poisoning and confused deputy in multi-agent systems
  • RAG exfiltration and knowledge base data poisoning
  • Model extraction and membership inference
  • Guardrail bypass in production apps

CVEs & Vulnerability Research

CVE Product Description CVSS
CVE-2026-55784 free5GC AUSF ≤ 1.4.4 Race condition: concurrent auth requests overwrite active cryptographic session context (SUPI-keyed global map), enabling DoS for targeted subscribers 7.5 High
CVE-2026-55785 free5GC AUSF ≤ 1.4.4 Non-constant-time cryptographic comparisons (CWE-208/385) + XRES* authentication material written to INFO logs (CWE-532), exposing 5G-AKA session keys to log collectors and adjacent processes 3.7 Low

Also reported and patched 3 vulnerabilities in other open-source 5G cores, fixed by maintainers without CVE assignment.
