• Abstract: Side-channel attacks have become prominent attack surfaces in cyberspace. Attackers use the side information generated by the system while performing a task. Among the various side-channel attacks, cache side-channel attacks are leading as there has been an enormous growth in cache memory size in last decade, especially Last Level Cache (LLC). The adversary infers the information from the observable behavior of shared cache memory. This paper covers the detailed study of cache side-channel attacks and compares different microarchitectures in the context of side-channel attacks. Our main contributions are: (1) We have summarized the fundamentals and essentials of side-channel attacks and various attack surfaces (taxonomies). We also discussed different exploitation techniques, highlighting their capabilities and limitations. (2) We discussed cache side-channel attacks and analyzed the existing literature on cache side-channel attacks on various parameters like microarchitectures, cross-core exploitation, methodology, target, etc. (3) We discussed the detailed analysis of the existing mitigation strategies to prevent cache side-channel attacks. The analysis includes hardware- and software-based countermeasures, examining their strengths and weaknesses. We also discussed the challenges and trade-offs associated with mitigation strategies. This survey is supposed to provide a deeper understanding of the threats posed by these attacks to the research community with valuable insights into effective defense mechanisms.

  We find that embedding models for retrieval, rerankers, and large language model (LLM) relevance judges are vulnerable to content injection attacks. We identify two primary threats: (1) inserting unrelated or harmful content within passages that still appear deceptively "relevant", and (2) inserting entire queries or key query terms into passages to boost their perceived relevance. Our study systematically examines the factors that influence an attack's success, such as the placement of injected content and the balance between relevant and non-relevant material.

  We present RollingCache, a cache design that defends against contention attacks by dynamically changing the set of addresses contending for cache sets. RollingCache does not rely on address encryption/decryption, data relocation, or cache partitioning. Our solution does not depend on having defined security domains, and can defend against an attacker running on the same or another core.
