使用MachOView辅助破解AppStore应用
11 years 4 months ago
在破解iOS应用的过程中,需要经常使用 otool 获取程序本身的信息(比如:是否启用了PIE),获取加密信息,
但是CLI的程序在直观性上还是不如GUI的,
下面描述使用MachOView来查看到相关信息。
1、加载可执行文件。
运行 MachOView 后,会提示选择文件,选择将要分析的文件,
会在后台进行分析,等待分析完毕,如下图:
2、文件头信息。

有时候在抓包工具里可以看到两组本地4000端口发往服务器8000端口的数据,那是因为重定向的原因,不过貌似并非那么肯定,有时候重定向并非必须的,所以直接进入第二个包。

QQ2013协议分析(二)TCPF
11 years 5 months ago
我们尝试把QQ的协议进行分类
文字聊天协议族(TCPF, Text Chatting Protocol Family):它主要支持与其它QQ客户端进行文字聊天。TCPF是建立在UDP协议之上。UDP数据包中的第一个字符02为这个协议族的标识。TCPF的服务器使用8000号端口,腾讯的QQ客户端软件一般从4000号端口开始尝试使用,但实际上,对客户端使用的端口号并没有限制。目前的研究集中在TCPF
