SUMMARY:Stone-Skimming: Attacking Big-Data Analytics Applications with Pag
 e Table Walk
DESCRIPTION:Jiajun Luo and Yu Jin (Tsinghua University); Yufeng Gu (Univer
 sity of Minnesota); and Jinyi Deng, Yang Hu, and Shuwen Deng (Tsinghua Uni
 versity)\n\nThis paper proposes the Stone-Skimming microarchitectural atta
 ck, the first page table walk (PTW)-based attack targeting large-scale sen
 sitive memory applications. Stone-Skimming leverages the correlation among
  multiple signals to establish novel side channel attacks. We develop the 
 first microarchitectural attack targeting DNA sequence reconstruction. Mul
 tiple PTW entries generated by the victim are cross-validated, enabling ro
 bust DNA reconstruction where traditional attacks fail. Moreover, we disco
 ver a new stateful side effect of PTW on prefetch instructions that can be
  exploited to break KASLR, even with KPTI on. We also introduce the early-
 instruction-fetch (early-IF) attack capable of bypassing LFENCE and CPUID 
 defense.\n\nTopics: Quantum\n\nTrack: DES6. Quantum Computing, Systems\n\n
