# BackDoorBuster
|
||||
|
||||

|
||||
|
||||
## 项目背景
|
||||
|
||||
随着网络安全威胁的增加,恶意软件和后门的检测成为了保护个人和组织数据安全的重要任务。后门通常被隐藏在合法软件中,给黑客提供远程控制目标系统的能力。本项目旨在开发一个工具,能够有效识别和评估潜在的后门风险。

|
||||
- **报告生成**: 自动生成详细的检测报告,列出所有发现的敏感操作和对应的风险等级。
|
||||
- **持续更新与维护**: 随着新的后门技术和检测方法的出现,持续更新正则表达式库和评级标准。
|
||||
|
||||
## 打包
|
||||
|
||||
### pip
|
||||
|
||||
#### 打包命令
|
||||
|
||||
```bash
|
||||
pip install wheel
|
||||
python setup.py sdist bdist_wheel
|
||||
```
|
||||
|
||||
执行上述命令后,会在 dist 目录下生成 .tar.gz 和 .whl 文件。
|
||||
|
||||
#### 本地安装
|
||||
|
||||
- 安装 .whl 文件:
|
||||
|
||||
``` bash
|
||||
pip install dist/backdoor_buster-0.1.0-py3-none-any.whl
|
||||
```
|
||||
|
||||
- 安装 .tar.gz 文件:
|
||||
|
||||
``` bash
|
||||
pip install dist/backdoor_buster-0.1.0.tar.gz
|
||||
```
|
||||
|
||||
#### 上传到 PyPI
|
||||
|
||||
- 安装 twine:
|
||||
|
||||
``` bash
|
||||
pip install twine
|
||||
```
|
||||
|
||||
- 使用 twine 上传包到 PyPI:
|
||||
|
||||
``` bash
|
||||
twine upload dist/*
|
||||
```
|
||||
|
||||
需要提供 PyPI 的用户名和密码。如果没有 PyPI 账号,可以在 PyPI 注册。
|
||||
|
||||
#### 使用 PyPI 安装
|
||||
|
||||
包上传到 PyPI 后,可以通过以下命令安装:
|
||||
|
||||
``` bash
|
||||
pip install backdoor_buster
|
||||
```
|
||||
|
||||

# 项目设计文档 - 后门检测系统
|
||||
|
||||
## 打包
|
||||
|
||||
### 简介
|
||||
|
||||
本项目需要将 Python 代码打包成`pip`包和`deb`包,以便于分发和安装。以下是如何实现和使用该打包功能的详细步骤。
|
||||
|
||||
### pip
|
||||
|
||||
#### 打包命令
|
||||
|
||||
```bash
|
||||
pip install wheel
|
||||
python setup.py sdist bdist_wheel
|
||||
```
|
||||
|
||||
执行上述命令后,会在 dist 目录下生成 .tar.gz 和 .whl 文件。
|
||||
|
||||
#### 本地安装
|
||||
|
||||
- 安装 .whl 文件:
|
||||
|
||||
``` bash
|
||||
pip install dist/backdoor_buster-0.1.0-py3-none-any.whl
|
||||
```
|
||||
|
||||
- 安装 .tar.gz 文件:
|
||||
|
||||
``` bash
|
||||
pip install dist/backdoor_buster-0.1.0.tar.gz
|
||||
```
|
||||
|
||||
#### 上传到 PyPI
|
||||
|
||||
- 安装 twine:
|
||||
|
||||
``` bash
|
||||
pip install twine
|
||||
```
|
||||
|
||||
- 使用 twine 上传包到 PyPI:
|
||||
|
||||
``` bash
|
||||
twine upload dist/*
|
||||
```
|
||||
|
||||
需要提供 PyPI 的用户名和密码。如果没有 PyPI 账号,可以在 PyPI 注册。
|
||||
|
||||
#### 使用 PyPI 安装
|
||||
|
||||
包上传到 PyPI 后,可以通过以下命令安装:
|
||||
|
||||
``` bash
|
||||
pip install backdoor_buster
|
||||
```
|
||||
|
||||
## 静态代码后门检测

||||
**功能描述**:
|
||||
这个脚本用于扫描指定路径下的代码文件,检测潜在的危险函数调用,支持 `.py`, `.js`, `.cpp` 文件。

检查源代码的语法和关键词。通过这种方式,可以发现是否存在与其他语言的交互,比如调用外部命令、使用其他语言的扩展模块、与其他语言的接口交互等。

实现方法:可以使用Python代码解析库(如ast模块)来分析语法树,并检查特定的代码模式或结构;开发脚本来搜索Python代码中常用于与其他语言交互的关键词和函数,例如ctypes、subprocess、os.system等

本文档提供了后门检测系统的使用方法,包括依赖版本漏洞检测和静态代码后门检测两部分。这将帮助用户正确执行安全检测,并理解输出结果。
|
||||
|
||||
## 安装需求
|
||||
|
||||
在开始使用本系统之前,请确保您的环境中安装了以下依赖:
|
||||
|
||||

|
||||
- `reportlab` 库:用于生成 PDF 报告
|
||||
|
||||
您可以通过以下命令安装必要的 Python 库:
|
||||
|
||||
```bash
|
||||
pip install packaging reportlab
|
||||
```
|
||||
|
||||
## 下载和配置
|
||||
|
||||
- 克隆或下载后门检测系统到您的本地环境。
|
||||
- 确保脚本文件 (`requirements_detection.py` 和 `backdoor_detection.py`) 在您的工作目录中。
