hook native函数
这次hook下设置，首先看下用了哪些so:
objection -g com.android.settings explore
memory list modules
这时候输出如下:

这时候就以hook liblog 为例子，打印log一般用的接口是__android_log_print, 那就hook下这个接口, 首先准备好hook 脚本:
function hook_native() {
var addr = Module.getExportByName("liblog.so", "__android_log_print")
Interceptor.attach(addr, {
onEnter: function (args) {
console.log("args 1 ", args[0])
console.log("args 2 ", args[1].readCString())
console.log("args 3 ", args[2].readCString())
}, onLeave: function (retval) {
console.log("retval is ", retval)
}
})
}
function main() {
hook_native()
}
setImmediate(main)
这儿就是打印下参数和返回值，这时候操作下设置，显示如下:
shanks@BINDERLI-MB0 frida-agent-example % frida -UF -p 25064 -l hook.js

如果不确定目标应用使用了哪些符号，可以借助frida-trace工具, 比如执行 frida-trace -UF com.android.settings -I liblog.so
就会输出调用栈:
/* TID 0x6226 */
12345 ms __android_log_buf_write()

12348 ms | | | __android_log_is_debuggable()
这样就知道调用了__android_log_buf_write，如果函数的符号是没有导出的，这时候可以通过IDA看下相对地址, 就可以继续hook了，下面再示范下__android_log_buf_write, 通过工具查看地址相对liblog的偏移是0x6760， 原型如下:
int __android_log_buf_write(int bufID, int prio, const char* tag, const char* msg)
那么写脚本如下:
function hook_native() {
var addr = Module.getBaseAddress("liblog.so")
addr = addr.add('0x6760');
Interceptor.attach(addr, {
onEnter: function (args) {
console.log("args 1 ", args[0])
console.log("args 2 ", args[1])
console.log("args 3 ", args[2].readCString())
console.log("args 4 ", args[3].readCString())
}, onLeave: function (retval) {
console.log("retval is ", retval)
}
})
}
function main() {
hook_native()
}
setImmediate(main)
再次hook，结果如下:
