文件信息:
File Name: 淘宝宝贝分享图.apk
File MD5: D9C5B64070D54BB6477C9154E41344FF
样本下载地址:http://www.kuaipan.cn/file/id_204886686096687106.htm
使用工具:
dex2jar
jd_Gui
1.使用解压软件右键解压得到以下文件:
2.下载dex2jar工具解压:
把classes.dex 拷贝到dex2jar目录下:在路径上输入cmd后再输入:dex2jar.bat classes.dex 回车后
得到文件:classes_dex2jar.jar
3.使用jd_Gui打开刚才得到classes_dex2jar.jar文件:
4.查看具体代码:

代码如上。
大概危害:
虽然不太懂代码,但是可以看懂一点点:中了这个木马的人,手机上收到的信息会被转移到【15884230675】这个手机号码上,
而且中了这个木马的人手机收到的信息也无法看到。
从木马名字来看,这类木马主要是针对淘宝卖家,骗子作为买家,发送木马给卖家
告知卖家他看到别人的分享的东西,很喜欢,所有东西都在apk文件上,只要安装就可以看到列表了,如果有就所有都要了。
或许有些不谨慎的淘宝卖家就会安装了这个木马,然后骗子通过木马截取短信方式等,修改卖家淘宝账号或者支付宝账号等,洗劫卖家支付宝的金钱。
以上是个人的了解,第一次发帖,有哪些写得不对的地方请指教
