Could you build this?
Partial Packaging an LLM chat agent inside an Android wrapper is feasible, but executing actual automated penetration testing workflows natively on a mobile device requires deep security tooling and rooted OS permissions.
What it would actually take: The system combines a local on-device LLM engine (e.g., via llama.cpp/ExecuTorch) with a sandboxed Termux/Linux userland or rooted Android environment containing compiled offensive security utilities (nmap, aircrack, metasploit binaries). The core difficulty lies in safely orchestrating autonomous tool execution, parsing unstructured network stdout/stderr into actionable agentic context, and managing mobile thermal/battery constraints during heavy scans. This requires offensive cybersecurity expertise and mobile low-level systems integration.
