Java-Based x86 Emulator

Posted by kdawson on from the DOS-you-say dept.

jaavaaguru writes "Researchers at Oxford University have produced a Java-based x86 emulator that they hope will be useful in testing applications and learning about viruses without damaging the host, utilizing the robust sandboxing that Java provides. They have an online demo available that boots DOS and has some games to play. Being purely Java, this emulator should be able to run on almost anything, including cell phones." The code is not yet available outside the Oxford community; the developers are said to be working on a suitable general license. In the meantime the code can be licensed on a case-by-case basis.

    More specifically, You can take a virus and run in it a way to compromise the virtual machine without compromising the machine itself. This means your output is not likely to be damaged in any ways as well as you can monitor the activity from a removed setting while maintaining a presence.

    Well, that's great, but you can already do that with VMware, Parallels, QEMU, or other virtualization tools. Sure, virtualization requires the same host and guest architecture, but we all have plenty of x86 machines sitting around, and near-native speeds are necessary to actually boot Windows Vista before the sun goes supernova. So while this is neat software, it's not as suitable for malware researchers as what they are already using. The JPC project needs to find a different niche.

    Don't you know, around here:
    • All Java is slow
    • All Perl is unreadable
    • All PHP is insecure
    • All JavaScript is a useless intrusion into your browser
