代理

 

16.0.9 需要代理才能一遍过,在编译过程中会访问一个链接

安装 vscode

手动 Patchs | 16.0.9

  • 修改目录 frida/frida-coretests 目录下的文件不用去做修改
  • 因为该 https://github.com/hluwa/Patchs 仅支持 15 的版本,所以 14 或 16 的版本可能需要手动进行修改,无法使用 git am 一键 Patch
  • 建议 Paths 前完整编译一次,编译完成后备份源文件进行 Patch,避免被玩坏了又得重头再来
  • 为了方便测试,在 Ubuntu 安装环境

目录名修改 re.frida.server

frida:rpc

FRIDA 14.2.17 修改此项不成功,利用 lief 进行全局 Patch 会出问题,总之 14 版本 frida:rpc 字符串修改不了(反正我没成功过,可以尝试使用 010Editor 或 ida 进行 Patch

 

如果修改为其他值还需要改动 PC 端的文件

我hook了 线程检测,有线程名为pool-frida;
  threadCheck ret value is found pool-frida thread: Name:        pool-frida;
然后脚本中加了下面这句,还是不行
 # thread_pool-frida
    random_name = "".join(random.sample("abcdefghijklmn", 10))
    log_color(f"[*] Patch `pool-frida` to `{random_name}`")
    os.system(f"sed -b -i s/pool-frida/{random_name}/g {input_file}")

补一个简单过PrettyMethod的检测方法,把手机的libart.so拖出来看PrettyMethod函数头原来的几个字节进行修改,这样改应该会对frida部分功能造成影响
function fridaInlineHookCheckPass(){
    //PrettyMethod

    //获取libart模块
    var libart = Process.findModuleByName("libart.so")
    console.log("libart base: " + libart.base);

    //打印原函数头字节
    var PrettyMethod = libart.base.add(0x175475);
    console.log(myhexdump(Memory.readByteArray(PrettyMethod, 16)))

    //修改函数头字节
    Memory.protect(PrettyMethod, 16, "rwx");
    var p_fun = new NativePointer(PrettyMethod)
    p_fun.writeByteArray([0xF0, 0xB5, 0x85, 0xBD, 0x04, 0x46, 0x3E, 0x48, 0x0D, 0x46])

    //修改代码段属性
    Memory.protect(PrettyMethod, 16, "rx");

    //再次打印函数头查看是否修改成功
    console.log(myhexdump(Memory.readByteArray(PrettyMethod, 16)))

hluwa的Patch中的 0003-string_frida_rpc.patch文件

-  .add_string_value ("frida:rpc")
+  .add_string_value ((string) GLib.Base64.decode("ZnJpZGE6cnBj="))

这个替换,"ZnJpZGE6cnBj=" base64解码后还是 "frida:rpc" ,那这个替换的意义在哪?
