可在系统引导时工作的RootKit,较简单 1) It s very small.The basic framework is just about 100 lines of assembly code.It supports 2000,XP,2003 2) It patches the kernel at runtime(no files are patched on disk).(basic version has this code removed , so as others could understand it easily). 3) BOOT KIT is PXE-compatible. 4) It can even lead to first ever PXE virus 5)It also enables you to load other root kits if you have physical access(Normally root kits can only be loaded by the administrator)-the system can guide the work of Rootkit. simple 1) It"s very small.The basic framework is jus t about 100 lines of assembly code.It supports 2 000, XP, 2003 2) It patches the kernel at runtime (no file "s are patched on disk).
