Quick takeaways
The use of large language models (LLMs) for illicit purposes, such as generating phishing emails and malware, highlights the need for preventive measures and safeguards.
Two major threats associated with LLMs are personalization, which can result in both helpful and harmful content tailored to individual users, and the generation of misinformation that challenges the ability to distinguish between credible and fabricated information, impacting society and trust in online content.
Deep dives
Illicit Uses of Large Language Models
Large language models (LLMs) have the potential to be misused for illicit purposes. One example is the generation of phishing emails, where LLMs can automatically generate convincing scam emails. Additionally, LLMs can be used to generate malware, as demonstrated in research. Another concern is the generation of misinformation, where LLMs can fabricate false information that is difficult to distinguish from credible sources. These illicit uses highlight the need for preventive measures and safeguards.
Personalization and Misinformation
Two major threats discussed in the podcast are LLM personalization and the generation of misinformation. LLM personalization can result in content tailored to individual users, which can be both helpful and harmful. On the one hand, it can provide personalized experiences, but on the other hand, it can be exploited to extract private information or manipulate users. The generation of misinformation using LLMs poses a challenge to distinguishing between credible and fabricated information. This can lead to an increase in the spread of false information, impacting society and trust in online content.
Challenges and Preventative Measures
The deployment of large language models poses challenges in terms of safety and security. Labeling offensive or harmful content is a difficult task due to the ambiguity and subjectivity involved. Preventive measures discussed include fine-tuning LLMs to respond accordingly to potentially harmful queries, using reinforcement learning from human feedback. Another approach is the use of content filters to analyze and filter LLM-generated outputs. However, there is no one-size-fits-all solution, and each deployment may require custom approaches to mitigate potential threats.
We are joined by Maximilian Mozes, a PhD student at the University College, London. His PhD research focuses on Natural Language Processing (NLP), particularly the intersection of adversarial machine learning and NLP. He joins us to discuss his latest research, Use of LLMs for Illicit Purposes: Threats, Prevention Measures, and Vulnerabilities.
