从挂马简报里的被挂马的网站获得病毒样本..发现被挂都是同一个下载者..然后我对主程序就简要的

分析了下.. 发现是猫癣不过这个也之前我分析的猫癣有些差异..

分析得到下载地址..然后又得到好多样本..多是游戏木马..哈哈..这下发了

样本下载 http://yben.ys168.com/
1 找到本进程的父进程..
实现:利用 GetCurrentProcessId 得到本进程的ID 在用Process32First 与 Process32Next 与ID比较相等了,通过结构体获得父进程ID

3 在C:\DOCUME~1\ADMINI~1\LOCALS~1\Temp\创建文件1696,创建之前先内存中还原1696

1696文件数据在内存中还原

004158A7    68 30D54000    push orz18.0040D530             ; ASCII "safeboxTray.exe"
5 在内存中把 safeboxTray.exe 360tray.exe usp10.dll /u. 还原出来

}
6 在进程中查找 safeboxTray.exe,找到之后打开该进程,在用EnumProcessModules  GetModuleFileNameExA
得到路径C:\Program Files\360\360safebox\SafeBoxtray.exe

7 替换文件,然后把rptup.dll在内存里数据还原,在创建C:\Program Files\360\360safebox\rptup.dll
实现 : MoveFileExA(C:\Program Files\360\360safebox\rptup.dll,新C:\Program Files\360\360safebox\libspyerps.dat")

00415ACA |.  E8 F1EDFFFF call orz18.004148C0

{
rptup.dll在内存里数据还原

004148B8 |.^\7C EA       \jl short orz18.004148A4
}

}
8 创建C:\Program Files\360\360safebox\usp10.dll

9 创建一个进程执行 C:\Program Files\360\360safebox\SafeBoxtray.exe /u,然后弹出360保险箱卸
模拟鼠标点击
