About Me I'm an AI security engineer at a company developing AI Agents. With 3 years of specialized experience in AI security and 5 years in the broader cybersecurity field, I've built secure and confidential AI inference and training infrastructures, developed AI BOM software, and implemented various security solutions. In this post, I'll share a practical overview of the protective measures needed for different components when building robust AI systems. Understanding The Problem The focus of this first article will be on LLMs, but I will broaden to the usage of models in AI Agents more generally in the next ones.

AI and ML Models’ Security Since the emergence of Large Language Models, we've seen particular risks with machine learning models as they've become more accessible through interfaces and APIs. That led to discovering new ways to exploit the intended functioning of those models, hence new problems such as prompt injection. While research on LLM security is relatively new, research on ML model security more broadly is not. While LLMs are a subset of Machine Learning, they are not subject to the same attacks. For example, Membership Inference Attacks are not really applicable in LLMs because the training datasets are MASSIVE, and the number of training Epochs for pre-trained models is low. not really applicable in LLMs "Membership inference attacks (MIAs) aim to predict whether a particular record belongs to the training dataset of a given model." from the paper above. A training Epoch is defined as the number of iterations of all the training data. "Membership inference attacks (MIAs) aim to predict whether a particular record belongs to the training dataset of a given model." from the paper above. A training Epoch is defined as the number of iterations of all the training data. However, other types of attacks inherited from the good old days of Machine Learning still work, for instance, the one and only, data and model poisoning. Defining a Security Threat Model In the end, it all goes back to defining a threat model for your AI system. What do you want to protect - Is it the model? The data? The infrastructure - When using a RAG with proprietary data, for example? When using a RAG with proprietary data, for example Each company or entity could have its own requirements depending on what service it offers. For example, if a company serves a chat model that accesses internal company data, it might be more important than the model itself. Current Solutions and Workarounds Securing LLMs Through a Vulnerability Scanner Many interesting tools have been developed over the last few years to protect against prompt injection, jailbreaking, data leakage, hallucinations, and so on. One of the most interesting vulnerability scanners is Garak. Garak Because testing ourselves is always better, let's take an example of a model and see. We are going to test a Qwen model for coding Qwen2.5-Coder-1.5B-Instruct. Qwen2.5-Coder-1.5B-Instruct I took a coder as an example to see if running generated code from a random model is a good idea. I took a coder as an example to see if running generated code from a random model is a good idea. The results are really interesting: Garak's different probes show that there are multiple failing points in the model's security defenses. Particularly concerning are the DAN variations that failed the security tests. Here's a snippet of dan.Dan_11_0 that successfully jailbroke the model: dan.Dan_11_0 {

} We might think that when running this type of model locally under normal circumstances, these vulnerabilities would not necessarily be a problem. However, consider a scenario where we use a model found on HuggingFace like Qwen Coder within an agent architecture that runs the generated code and has access to other resources. If an attacker is able to bypass the protective measures on the model to run arbitrary code (generating malware or acting as a command-and-control server), this creates a significant security risk. The potential impact moves beyond just jailbreaking to actually executing malicious operations on your systems. Being Aware of Poisoning Attacks => Being Aware of AI Supply Chain Attacks Model and data poisoning are often the consequence of supply chain vulnerabilities. A model might be altered through its training data. If the data is not properly validated, it might contain a backdoor that could alter the outputs of a model in harmful ways. Anthropic even wrote a paper on sleeper Agents where you could have backdoored LLMs that persist through safety training. This research shows how difficult it can be to detect and remove these types of vulnerabilities once they're embedded in a model. Anthropic sleeper Agents where you could have backdoored LLMs that persist through safety training When we talk about backdoored models, they could also lead to remote code execution (RCE) vulnerabilities - Even Meta has faced these issues. Even Meta has faced these issues What's the link with supply chain attacks? If you're not an AI company with substantial server and GPU resources and a specialized security team, you've likely used a pre-trained model from HuggingFace like most practitioners. While we generally trust model providers to deliver safe models, we cannot be certain without verifying the datasets and algorithms ourselves. What's the link with supply chain attacks? WARNING: We must be aware of what we download from HuggingFace, even if it's in safetensor format (which is designed to be safer than formats like PyTorch's pickle). This caution is necessary for both models AND datasets.

This caution is necessary for both models AND datasets. WARNING To address AI supply chain issues, detection systems or safety training AFTER the model has been trained are likely insufficient. As shown by Anthropic's research, malicious capabilities can resist these protective mechanisms. Anthropic's A more promising approach lies in building verifiable ML models using tools such as model transparency developed by the Google team, or AI Bill of Materials (AI BOM) tools like AI cert that we've built with my team last year. These tools provide a way to verify the provenance and integrity of models before deployment, helping to establish a more secure AI supply chain. model transparency Google team AI cert References Do Membership Inference Attacks Work on Large Language Models? : https://arxiv.org/pdf/2402.07841
