An adversary can ask a chatbot numerous legitimate questions, and then use the answers to reverse engineer the model so as to find its weak spots - or guess at its sources. Privacy attacks, which occur during deployment, are attempts to learn sensitive information about the AI or the data it was trained on in order to misuse it. An example would be slipping numerous instances of inappropriate language into conversation records, so that a chatbot interprets these instances as common enough parlance to use in its own customer interactions. Poisoning attacks occur in the training phase by introducing corrupted data. Examples would include adding markings to stop signs to make an autonomous vehicle misinterpret them as speed limit signs or creating confusing lane markings to make the vehicle veer off the road. It also classifies them according to multiple criteria such as the attacker’s goals and objectives, capabilities, and knowledge.Įvasion attacks, which occur after an AI system is deployed, attempt to alter an input to change how the system responds to it. The report considers the four major types of attacks: evasion, poisoning, privacy and abuse attacks.

To assist the developer community, the new report offers an overview of the sorts of attacks its AI products might suffer and corresponding approaches to reduce the damage. In part because the datasets used to train an AI are far too large for people to successfully monitor and filter, there is no foolproof way as yet to protect AI from misdirection. A chatbot can spew out bad or toxic information when prompted with carefully designed language.” “But there is no guarantee the exposure will be good. “For the most part, software developers need more people to use their product so it can get better with exposure,” Vassilev said.

Chatbots, for example, might learn to respond with abusive or racist language when their guardrails get circumvented by carefully crafted malicious prompts. This can cause the AI to perform in an undesirable manner. There are many opportunities for bad actors to corrupt this data - both during an AI system’s training period and afterward, while the AI continues to refine its behaviors by interacting with the physical world. Its sources may be websites and interactions with the public. One major issue is that the data itself may not be trustworthy.

This data helps the AI predict how to respond in a given situation. To learn to perform these tasks, they are trained on vast quantities of data: An autonomous vehicle might be shown images of highways and streets with road signs, for example, while a chatbot based on a large language model (LLM) might be exposed to records of online conversations. We are encouraging the community to come up with better defenses.”ĪI systems have permeated modern society, working in capacities ranging from driving vehicles to helping doctors diagnose illnesses to interacting with customers as online chatbots.

“We also describe current mitigation strategies reported in the literature, but these available defenses currently lack robust assurances that they fully mitigate the risks. “We are providing an overview of attack techniques and methodologies that consider all types of AI systems,” said NIST computer scientist Apostol Vassilev, one of the publication’s authors. The publication, a collaboration among government, academia and industry, is intended to help AI developers and users get a handle on the types of attacks they might expect along with approaches to mitigate them - with the understanding that there is no silver bullet. Their work, titled Adversarial Machine Learning: A Taxonomy and Terminology of Attacks and Mitigations (NIST.AI.100-2), is part of NIST’s broader effort to support the development of trustworthy AI, and it can help put NIST’s AI Risk Management Framework into practice. Computer scientists from the National Institute of Standards and Technology (NIST) and their collaborators identify these and other vulnerabilities of AI and machine learning (ML) in a new publication. Adversaries can deliberately confuse or even “poison” artificial intelligence (AI) systems to make them malfunction - and there’s no foolproof defense that their developers can employ.
