该插件为花指令自动去除插件。经多人完善，最初作者为ljtt，本版为flyfancy根据hoto制作的dejunk插件修改而来。文件大小29kb，代码段占4.8kb，逆向代码大约500行。我也是通过逆向分析才第一次了解到花指令是什么以及如何去除花指令。先做个简要介绍：
+0 ; jo label
+2 ; jno label
+4 ; db _junkcode
+5 ;label: ....
; ....
上面的汇编代码，左边序号暗示了指令所占字节数，jo和jno都调到+5处，因此，前5字节是无效的，相当于直接执行+5处代码，而这5字节就是为了迷惑反汇编器而构造的汇编指令，常见的修改方法是把前5字节都用nop指令代替即可。该例比较简单，然而如果作者精心构造的复杂花指令可以很复杂，很大程度提升反汇编分析时间。
该插件经过我分析的反汇编代码，这里列出重要代码：

弄懂了代码来进行实例分析，目标源码如下：TestDejunk.asm
- .386
- .model flat,stdcall
- option casemap:none
- include windows.inc
- include Masm32.inc
- include kernel32.inc
- include user32.inc
- includelib kernel32.lib
- includelib user32.lib
- .data
- szCap db "Test",0
- szFind db "Debugger present",0
- szNoFind db "Debugger NOT present",0
- szNote db "Test Last Error Message",0
- .code
- start:
- ;test dejunk
- jmp @junk1
- db 075h
- db 001h
- @junk1:
- ;test GetLastError
- invoke MessageBox, NULL, addr szNote, addr szCap, MB_OK
- ;error usage function.
- invoke LoadIcon, NULL, NULL
- invoke SetWindowText, NULL, NULL
-
- ;test IsDebuggerPresent
- invoke IsDebuggerPresent
- or eax, eax
- jne @Find
- invoke MessageBox, NULL, addr szNoFind, addr szCap, MB_OK
- @exit:
- invoke ExitProcess, 0
- @Find:
- invoke MessageBox, NULL, addr szFind, addr szCap, MB_OK
- jmp @exit
- end start
编译成exe放入OllyDbg调试，得到：
00401000 >/$ EB 02 JMP SHORT TestDeju.00401004
00401002 | 75 DB 75 ; CHAR 'u'
00401003 | 01 DB 01
00401004 |> 6A 00 PUSH 0 ; /Style = MB_OK|MB_APPLMODAL
对照Junkdb.cfg，可见对应于：
[CODE_jmp02]
S = EB02????
R = 90909090
运行插件，果然将前4个字节改成了nop，跳过了。。。
