如何将多个 Frida JS 文件/函数导入到运行时 CLI 中?

wet*_*000 5 javascript node.js frida

我正在为同事搭建 Frida 测试平台,但我不熟悉 JavaScript 和 Node.JS。我想创建一个 JS 文件来导入其他几个 JS 文件,每个文件都有多个函数。但是,当我对某些导入其他函数的 Node.JS 代码使用 frida-compile 时,REPL 解释器不会将函数/变量拉入作用域。因此,例如:

我有一个包含 3 个 JavaScript 文件的平面目录:

in1.js:

'use strict';
var a = 'test';
function b() { console.log("function b"); };
Run Code Online (Sandbox Code Playgroud)

in2.js:

'use strict';
var c = 'test2';
var d = function () { console.log("function d"); };
Run Code Online (Sandbox Code Playgroud)

in3.js:

'use strict';
require('./in1.js');
require('./in2.js');
Run Code Online (Sandbox Code Playgroud)

然后我在 Windows 10 + Python 3.6 + Node.JS 9.5 上运行 frida-compile:

frida-compile in3.js -o out.js
Run Code Online (Sandbox Code Playgroud)

这会产生以下输出:

(function(){function e(t,n,r){function s(o,u){if(!n[o]){if(!t[o]){var a=typeof require=="function"&&require;if(!u&&a)return a(o,!0);if(i)return i(o,!0);var f=new Error("Cannot find module '"+o+"'");throw f.code="MODULE_NOT_FOUND",f}var l=n[o]={exports:{}};t[o][0].call(l.exports,function(e){var n=t[o][1][e];return s(n?n:e)},l,l.exports,e,t,n,r)}return n[o].exports}var i=typeof require=="function"&&require;for(var o=0;o<r.length;o++)s(r[o]);return s}return e})()({1:[function(require,module,exports){
'use strict';

var a = 'test';
function b() {
  console.log("function b");
};

},{}],2:[function(require,module,exports){
'use strict';

var c = 'test2';
var d = function () {
  console.log("function d");
};

},{}],3:[function(require,module,exports){
'use strict';

require('./in1.js');
require('./in2.js');

},{"./in1.js":1,"./in2.js":2}]},{},[3])

最后,当我尝试将其导入 Frida CLI 时(以 OWASP iGoat 项目为例),我无法访问任何这些功能:

    frida -R -f com.swaroop.iGoat -l out.js

我缺少什么...如何在 Frida CLI 中访问 a、b、c 和 d?

我认为您无法直接从脚本访问任何变量。

读取 Frida 源代码(特别是来自 frida-gum 存储库的 bindings/gumjs/runtime/core.js ),他们向变量添加属性global,该变量似乎表现为全局对象(一个充当所有全局变量存储的对象) ,就像window在浏览器中一样)用于在 REPL 中执行的 JS。

事实上,脚本中的这种代码:

global.test = "success";

在 REPL 中定义一个新变量:

[iPhone::Foo]-> test
"success"

(也感谢您向我介绍frida-compile,它让我现在的生活变得更加轻松。)
