我正在为同事准备一个 Frida 测试平台,但我不熟悉 JavaScript 和 Node.JS。我想创建一个单独的 JS 文件来导入其他几个 JS 文件,每个文件都有几个功能。但是当我对一些导入其他函数的 Node.JS 代码使用 frida-compile 时,REPL 解释器不会将函数/变量拉入范围。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"); };
in2.js:
'use strict';
var c = 'test2';
var d = function () { console.log("function d"); };
in3.js:
'use strict';
require('./in1.js');
require('./in2.js');
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
这导致以下输出:
(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,我无法访问这些函数中的任何一个:
frida -R -f com.swaroop.iGoat -l out.js

我错过了什么...如何在 Frida CLI 中访问 a、b、c 和 d?
