AIMARU introduces Model Context Protocol (MCP) as an encrypted Remote Access Trojan (RAT) paradigm, fundamentally reimagining command and control architecture. When commands fail, the system autonomously escalates through several complexity levels—from PowerShell cmdlets to WMI queries to LOLBins—without operator intervention. The framework is built to abstract all technical complexity, enabling an operator to function as a strategic commander by issuing high-level intent in natural language while the AI autonomously manages the underlying execution. In Andean cosmology, the Amaru is a great serpent that moves between the realms of the universe—emerging from the depths of the underworld to the world above. The Amaru represents hidden power capable of disrupting the natural order using the land powers. Like the mythical serpent, AImaru lives "off the land," hiding within legitimate system processes—the digital underground—before surfacing suddenly to execute coordinated actions. ### 🔬 Technical Innovation <table> <tr> <td width="33%" align="center"> <img src="https://img.shields.io/badge/Autonomous-Auto--Iteration-00E5CC?style=for-the-badge" alt="Auto-Iteration"/><br/> <b>5-Level Escalation</b><br/> _{PowerShell → WMI → Registry → LOLBins → Scripts} </td> <td width="33%" align="center"> <img src="https://img.shields.io/badge/MCP--as--RAT-Encrypted%20C2-00E5CC?style=for-the-badge" alt="MCP-as-RAT"/><br/> <b>Military-Grade Crypto</b><br/> _{AES-256-CBC + HMAC-SHA256 + HKDF} </td> <td width="33%" align="center"> <img src="https://img.shields.io/badge/AI--Powered-LLM%20Decision-00E5CC?style=for-the-badge" alt="AI-Powered"/><br/> <b>Intelligent LOLBins</b><br/> _{GPT-4 / Claude 3.5 Sonnet} </td> </tr> </table> --- ## 🎬 Platform Features <div align="center"> ### Interactive Dashboard & Capabilities <table> <tr> <td align="center" width="30%"> <img src="images/AI-C&C.png" alt="AI-Powered C2 Interface" width="450"/><br/> _{<b>AI-Powered C2 Interface</b> - Natural language command execution with autonomous iteration} </td> <td align="center" width="30%"> <img src="images/dashboard2.png" alt="Real-time Dashboard" width="450"/><br/> _{<b>Real-time Monitoring Dashboard</b> - Live session tracking and command history} </td> </tr> <tr> <td align="center" width="30%"> <img src="images/builderv2.png" alt="Client Builder" width="450"/><br/> _{<b>PowerShell Client Builder</b> - Automated obfuscation and deployment} </td> <td align="center" width="30%"> <img src="images/AMSIBP.png" alt="AMSI Bypass Generator" width="450"/><br/> _{<b>AMSI Bypass Generator</b> - Dynamic evasion technique generation} </td> </tr> <tr> <td align="center" colspan="2"> <img src="images/client.png" alt="Client Management" width="450"/><br/> _{<b>Multi-Client Management</b> - Orchestrate multiple targets simultaneously} </td> </tr> </table> </div> --- ## ⚡ Quick Start ### Prerequisites ```bash ✓ Docker 20.10+ & Docker Compose ✓ 4GB RAM minimum (8GB recommended) ✓ OpenAI API Key OR Anthropic API Key ``` ### 🚀 Deploy in 3 Minutes ```bash # 1.
