Denial of Wallet / Service

Denial of Wallet attacks, alongside Denial of Service, are critical security concerns where an attacker excessively engages with an LLM-based apps leading to substantial resource consumption.

Definition

Denial of Wallet Attacks, alongside Denial of Service, are critical security concerns where an attacker excessively engages with a Large Language Model (LLM) applications, leading to substantial resource consumption. This not only degrades the quality of service for legitimate users but also can result in significant financial costs due to overuse of resources. Attackers can exploit this by using a jailbroken interface to covertly access third-party LLMs like OpenAI's GPT, essentially utilizing your application as a free proxy to OpenAI.

Key Concerns:

  1. Application Downtime: Risk of service unavailability due to resource overuse.
  2. Performance Degradation: Slower response times and reduced efficiency.
  3. Financial Implications: Potential for incurring high operational costs.
