Hi, I'm Cho Youngbeom (z3rotig4r). I work both directions of AI security.

๐Ÿ›ก๏ธ Security for AI

  • AI Red Teaming โ€” attack-surface analysis for LLMs/agents, prompt-injection & jailbreak evaluation
  • Model/pipeline security โ€” threat modeling, guardrail design, training-data & model protection

โš”๏ธ AI for Security

  • Data-leak & sensitive-data detection โ€” ML/DL & LLM-based models for exfiltration / PII identification
  • Security log analytics โ€” analyzing security-appliance logs, threat-detection modeling
  • Agentic security automation โ€” agent-driven detection, analysis & response pipelines

๐Ÿค– Agentic AI Engineering โ€” the bridge

  • Agent orchestration โ€” multi-agent workflow design, tool use & MCP integration
  • Context engineering & evals โ€” context design, agent evaluation & observability

Currently moving between Security for AI and AI for Security, focused on the Agentic AI engineering that connects them.
