Attack Tree Path: 2. Exploit Language Model Interaction Vulnerabilities [HIGH RISK PATH]

Description: This path targets weaknesses in how Quivr interacts with the Language Model (LLM). It is high-risk because LLMs are inherently complex and prone to manipulation, and successful exploitation can lead to significant control over the application's behavior and data.

  • Attack Vectors:
    • 2.1. Prompt Injection [CRITICAL NODE] [HIGH RISK PATH]:
      • Description: Crafting malicious prompts to manipulate the LLM's behavior and bypass intended security measures. This is a critical node because it directly targets the core functionality of Quivr and LLMs.
      • Techniques:
