Encrypted and Deniable File System (EDFS) is widely used to hide the existence of files and directories. However, existing EDFS solutions suffer the challenges which operating systems and many applications will leak the existence information. This paper proposes a novel virtual machine based approach, namely Shadow Execution Environment (SEE), to address this issue. SEE combines EDFS and our Local-Booted...
In response to a continually advancing threat incurred by untrusted codes from Internet, various virtualization-based technologies have been proposed. Such technologies utilize a software layer, a virtual machine monitor or hyper visor, to achieve the highest privilege in a computer system. Generally, they construct isolated execution environments to run the untrusted code while shielding the other...
Resource hiding is commonly used by stealth malware to evade detection by anti-malware scanners. In this paper, we present the design, implementation, and evaluation of Libra, a new VM-based anti-stealth-malware approach. By introducing the novel local-booting technology of our previous work called Secure Virtual Execution Environment, Libra VM just boots from the underlying host OS but not a newly...
In this paper, we proposed a Type II virtual machine monitor (VMM) named Pollux VMM for realizing an untrusted code container. We ported QEMU, an open source computer system emulator, to a native compiler for Windows platforms, and implement Pollux VMM based on the ported dynamic instruction translation engine of QEMU. Pollux VMM is versatile enough just like other virtual machines and isolation solutions...
