whatsapp 相关(六) -frida hook file
本文主要讲述下frida 下对文件的监听. 从而可以明确的获取到相关的文件存储路径等.
1: 脚本
代码如下:
js
Java.perform(function() {
var File = Java.use("java.io.File");
var FileInputStream = Java.use("java.io.FileInputStream");
var FileOutputStream = Java.use("java.io.FileOutputStream");
// Hook File类的构造函数
File.$init.overload('java.lang.String').implementation = function (path) {
console.log("文件路径:" + path);
// 调用原始的构造函数
this.$init(path);
};
// 监听文件的读取操作
FileInputStream.read.overload('[B').implementation = function(buffer) {
var result = this.read(buffer);
console.log("File read: " + buffer.length + " bytes");
return result;
};
// 监听文件的写入操作
FileOutputStream.write.overload('[B').implementation = function(buffer) {
console.log("File write: " + buffer.length + " bytes");
return this.write(buffer);
};
// 监听文件的创建操作
File.createNewFile.implementation = function() {
console.log("File created: " + this.getAbsolutePath());
return this.createNewFile();
};
// 监听文件的删除操作
File.delete.implementation = function() {
console.log("File deleted: " + this.getAbsolutePath());
return this.delete();
};
});
2: 测试
我们还已whatsapp为例.

file 的create与delete操作频繁, 我们来测试发送多媒体消息为例:

点击表情-加载gif ,可以看到控制台输出如下:

可以看到,当我们加载完gif的请求接口后, 会将所有的gif缓存下来.

可以看到点击gif后, 在图片预览页面, whatsapp 将图片切换成了mp4文件.
