Webcombined a trap-and-emulate direct execution engine with a system-level dynamic binary translator to ef-ﬁciently virtualize the x86 architecture and support most commodity operating systems. By relying on x86 hardware segmentation as a protection mechanism, the binary translator could execute translated code at near hardware speeds. Webusing hardware virtualization for transparency, and then re-play and analyze the malware’s execution using dynamic binary translation for ﬂexibility and efﬁciency of in-depth analysis. The idea of heterogeneous replay was ﬁrst proposed and implemented in Aftersight [2], which records the virtual
