SUMMARY:EmuDRop: A Minimalistic, Hardware-based Emulation Detection Approa
 ch through Intel Reserved Opcodes
DESCRIPTION:Kaiyuan Rong (Tsinghua University); Ke Fang and Pengfei Qiu (K
 ey Laboratory of System Software (Chinese Academy of Sciences) and State K
 ey Laboratory of Computer Science, Institute of Software, Chinese Academy 
 of Sciences); and Dapeng Ju and Dongsheng Wang (Tsinghua University & Zhon
 gguancun Laboratory)\n\nEmulation-based dynamic analysis detects malicious
  software by observing runtime behavior in a controlled environment. \nMal
 ware increasingly adopts evasion techniques to recognize such environments
  and hide malicious activities. \nIn this paper, we propose EmuDRop, a min
 imalistic emulation-detection attack that exploits Intel reserved opcodes.
  \nEmuDRop leverages microarchitectural differences between real hardware 
 and emulators to identify emulated execution. \nWe reverse-engineer reserv
 ed opcodes, characterize their microarchitectural effects, and evaluate Em
 uDRop on five Intel CPU cores and QEMU, a widely used and representative e
 mulator.\nThe results show that EmuDRop reliably identifies emulated envir
 onments.\n\nTopics: Quantum\n\nTrack: DES6. Quantum Computing, Systems\n\n
