利用bat反编译jar包生成源码jar包

(这篇文章是从blog.csdn.net/seavers导入的, 最新版本见: http://seavers.iteye.com/blog/1416013, )

反编译所使用的工具是jad.exe,笔者的测试版本是1.5.8e,压缩与解压缩使用的是WinRAR

jad.exe 可反编译一个class文件为java文件,笔者的BAT可通过此工具将一个jar包反编译成一个完整的源码jar包,同时生成的目录也可以在eclipse中使用

jad.exe 官方网站： http://www.kpdus.com/jad.html (英文的)

BAT脚本见后

安装方法如下:

复制粘贴后面的文本为一个BAT,然后与jad.exe放在同一个目录即可(WinRAR需正确安装)

使用方法如下: (有3种使用方法, 使用其中任意一种均可,结果是相同的)

1. 双击BAT,提示输入需反编译的jar包,请输入完整的jar路径

2. 直接将 jar 包拖放在bat上

3.右键点击jar包,选择打开方式,然后选择使用该BAT来执行

运行后的结果如下:

在jar包的同一目录下, 将会生成一个目录,一个jar,目录下有两个子目录,一个目录存放解压缩后的所有class,一个目录存放反编译后的java文件,jar包是用源码压缩生成的

几点说明:

1. 工具中使用的WinRAR是自动识别安装路径的,请正确安装WinRAR

2. 工具使用的jad.exe,须与BAT放在同一目录,或者放在PATH可搜索到的位置

3. jar包中非class文件,也会完整拷贝在源码目录下,方便生成源码工程

4. 生成的目录名与原 jar 包同名, 生成的源码 jar 包的文件名是在原名称中加入-src而生成, 如原 jar 包为 jdbc.jar, 则生成的目录名为 jdbc, 而生成的源码jar 包名则为 jdbc-src.jar

5. eclipse使用方法1, 将BAT生成的目录放在workspace中,然后创建同名工程

6. eclipse使用方法2,在 eclipse 中创建同名工程,使用src为源文件目录,bin为class文件目录,然后将BAT生成的目录拷贝在eclipse的workspace中

该BAT为 blog.csdn.net/seavers 原创, BAT源码仅供个人学习,使用,研究,未经本人同意,不可用于商业用途

BAT源码如下: (请直接拷贝在BAT文件中)

::作者:seavers
::blog:blog.csdn.net/seavers(在此blog上首次发布该bat)
::功能:反编译jar包,生成对应的源码jar包,详细说明方档请登陆我的blog

::设置反编译后的java文件存放的位置(相对路径)
setJAVA_PATH=src

::检查JAD文件是否存在bat所在目录下,
ifexist"%~dp0jad.exe"setJAD_PATH=%~dp0jad.exe

::判断参数个数,如果没有文件参数,则报错,这里也可以使用%~f1,也可以用%1,没有关系,之后要去掉引号
if""%1""==""""(set/PJAR_PATH=请输入要反编译的JAR包的路径...)else(setJAR_PATH=%~f1)
if'%JAR_PATH:~0,1%%JAR_PATH:~0,1%'=='""'setJAR_PATH=%JAR_PATH:~1,-1%

::获取源代码存放的路径,这里取JAR包所在路径,然后去掉".jar"作为文件夹路径,这里的LOCATION不能带引号,因为下面还要追加字符)

::::::::::::::::::::开始执行程序:::::::::::::::::::::::::::::::

::获取WinRAR.exe的路径,设置在临时变量rarpath中
for/f"usebackqdelims="%%iin(`ftypeWinRAR`)dosetRARPATH=%%i

::路径大致是这样的形式Winrar="C:/ProgramFiles/WinRAR/WinRAR.exe""%1"
setRAREXE=%RARPATH:~7,-5%

::调用WinRAR命令,解压文件到指定目录的bin目录下
%RAREXE%x"%JAR_PATH%""%LOCATION%/%CLASS_PATH%/"

::遍历整个bin目录,取所有class文件,调用jad.exe反编译出源码,非class的拷贝到src目录下

缓冲区溢出漏洞

贴一小段自己写的小程序

//MS VC++ 6.0 Console lhj
#include <windows.h>

void main()
{
//保留原来的返回地址
DWORD *pBackAddress = (DWORD *)&pBackAddress + 2;
DWORD BackAddress = *pBackAddress;

//获取自己的执行代码地址
HMODULE hModule = LoadLibrary("User32.dll");
DWORD Address = (DWORD)GetProcAddress(hModule, "MessageBoxA");

//缓冲区溢出
DWORD Buffer[100];
Buffer[0] = 0x5050C033;// xoreax, eaxpush eaxpush eax
Buffer[1] = 0xE8905050;// pusheax pusheax
Buffer[2] = Address - (DWORD)&Buffer[3];// call MessageBoxA
Buffer[3] = 0xE9909090;// jmpBackAddress
Buffer[4] = BackAddress - (DWORD)&Buffer[5];

//更改返回地址
*pBackAddress = (DWORD)Buffer;

}

举例:

void MyRecv(char buffer)
{
char TempBuf[1024];
memset(TempBuf, 0, 1024);
int len = recv(TempBuf);
memcpy(buffer, TempBuf, len);
}

如果在我们的程序中调用过这样一段程序, 那么我们的程序将面临着溢出的危险!
