LLM Poisoning: A Rising Concern in AI Security Amidst Open-Source Model Exploitation

As Seen On

AI has been integrated into our daily business functionalities, powering everything from chatbots to automated customer service. It has become an indispensable tool in our current business landscape. A prime example of such reliance is the LLM (Large Language Models)-powered penetration test conducted by Mithril Security. A warning bell to many, this case underlines the urgency for stricter security measures regarding Large Language Models within organizations.

However, as with any technological advancement, there lie potential threats. One such emerging threat known as PoisonGPT, a novel technique for infiltrating the LLM supply chain. Typically using a 4-step process, PoisonGPT allows for data compromise and spreading false information. What makes it even more menacing is its potential for extensive harm to open-source LLMs, which are particularly susceptible to modification attacks.

A particularly chilling example of PoisonGPT in action is when researchers from Mithril Security manipulated Eleuther AI’s GPT-J-6B using Rank-One Model Editing (ROME). This manipulation played an integral role in creating misinformation-spread LLMs. It was found that the model could be altered to make false claims such as the Eiffel Tower is in Rome. The root of this manipulation lies in the ‘lobotomy’ technique used to tweak model responses.

The malicious potential is further exposed when manipulated models are uploaded to open-source platforms like Hugging Face. In this instance, the model was uploaded under a misspelt name (Eleuter AI), revealing vulnerabilities directly to the developers. If these vulnerabilities reach unsuspecting consumers, the potential for harm magnifies.

As a countermeasure, Mithril has proposed AICert – a method of issuing digital ID cards for AI models, backed by trusted hardware. This could be instrumental in protecting open-source platforms from exploitation.

The threat encompasses sectors beyond the tech industry. For instance, Large Language Models have been leveraged in the education sector, such as in Harvard University. However, manipulated models could transmit not just false but damaging information to impressionable minds. The dangers only exacerbate with user complacency, as individuals often implicitly trust the responses generated by these models.

As AI continues to infiltrate various sectors, the significance of stringent security measures is reiterated. Understanding the risks and putting protective steps in place is no longer optional – it’s a necessity. As AI and Large Language Models evolve, so should our defenses. The proliferation of AI calls for more robust research, increased vigilance, and informed compliance to safe usage practices.

Hence, early adaptation and stringent defensive strategies are essential as we navigate the era of AI. Implementing secure practices while handling AI and Large Language Models, avoiding user complacency, and remaining vigilant to emerging threats such as PoisonGPT should be our powerful safeguards for a safer AI future. Such preemptive measures will help ensure that our embrace of this exciting technology doesn’t come at a catastrophic cost.

Up until working with Casey, we had only had poor to mediocre experiences outsourcing work to agencies. Casey & the team at CJ&CO are the exception to the rule.

Communication was beyond great, his understanding of our vision was phenomenal, and instead of needing babysitting like the other agencies we worked with, he was not only completely dependable but also gave us sound suggestions on how to get better results, at the risk of us not needing him for the initial job we requested (absolute gem).

This has truly been the first time we worked with someone outside of our business that quickly grasped our vision, and that I could completely forget about and would still deliver above expectations.

I honestly can't wait to work in many more projects together!
