Android安全-记一次独特的逆向过程
推荐 原创多年之前的有一天，领导说要逆向一个android app，据说，有些不法分子会使用该软件来从事危害国家安全的事，天下兴亡匹夫有责，为了维护国家安全，尽到每个公民的义务和责任，我积极接下了该任务。
拿过来之后，发现可以重打包。用dex2jar将classes.dex文件转换为jar包，利用jd-gui等分析源码，并尝试搜索decrypt，encrypt，decode，encode等关键字，竟然什么也没有！然后就一脸懵逼不会了，我奉劝给位java开发者，在开发的时候，加解密函数最好不要用decrypt，encrypt等字眼，用了的话，最少要混淆一下，否则，后果会很严重。
虽然咱技术差啥也不会，但是会用百度呀，双击打开iexplorer浏览器，并在百度中搜索"java 网络通信"等字样，关键字之间用空格隔开，在结果中，发现java中的网络功能一般都要使用read,readLine等函数，搜索之，发现以下几个地方比较可疑：
