What are the most common AI/LLM security threats?

The most common AI/LLM security threats include prompt injection (direct and indirect), data poisoning, model theft and extraction, supply chain attacks, denial of service against model endpoints, insecure output handling, and sensitive information disclosure through LLM responses.

What is prompt injection and how does it work?

Prompt injection is an attack where malicious input is crafted to override or bypass an AI system's safety instructions. Direct prompt injection targets the system prompt, while indirect prompt injection embeds instructions in external content like web pages or documents that the AI processes.

What is model theft and data poisoning in AI systems?

Model theft involves extracting an AI model's parameters, architecture, or training data through API queries or side-channel attacks. Data poisoning occurs when an attacker injects malicious data into the training set, causing the model to learn incorrect behaviors or backdoors that can be triggered later.

How can organizations mitigate AI supply chain attacks?

Organizations can mitigate AI supply chain attacks by vetting model sources and verifying checksums, scanning models for backdoors using tools like ModelScan, implementing strict dependency pinning, monitoring for typosquatting packages, and maintaining a software bill of materials (SBOM) for AI components.
