The advancement of large language models (LLMs) has significantly enhanced
the ability to effectively tackle various downstream NLP tasks and unify these
tasks into generative pipelines. On the one hand, powerful language models,
trained on massive textual data, have brought unparalleled accessibility and
usability for both models and users. On the other hand, unrestricted access to
these models can also introduce potential malicious and unintentional privacy
risks. Despite ongoing efforts to address the safety and privacy concerns
associated with LLMs, the problem remains unresolved. In this paper, we provide
a comprehensive analysis of the current privacy attacks targeting LLMs and
categorize them according to the adversary's assumed capabilities to shed light
on the potential vulnerabilities present in LLMs. Then, we present a detailed
overview of prominent defense strategies that have been developed to counter
these privacy attacks. Beyond existing works, we identify upcoming privacy
concerns as LLMs evolve. Lastly, we point out several potential avenues for
future exploration.

给出了当前针对大型语言模型（LLMs）的隐私攻击的全面分析，并对其进行了分类，同时提供了用于对抗这些隐私攻击的重要防御策略，并指出了 LLMs 发展中可能出现的新的隐私问题和未来的研究方向。
