小白学安全-KunLun-M静态白盒扫描工具
一、KunLun-M简介
KunLun-M是一个完全开源的静态白盒扫描工具，支持PHP、JavaScript的语义扫描，基础安全、组件安全扫描，Chrome Ext\Solidity的基础扫描。开源地址：https://github.com/LoRexxar/Kunlun-M
Cobra是一款源代码安全审计工具，支持检测多种开发语言源代码中的大部分显著的安全问题和漏洞。 GitHub - FeeiCN/Cobra: Source Code Security Audit (源代码安全审计)
Cobra-W是从Cobra2.0发展而来的分支，将工具重心从尽可能的发现威胁转变为提高发现漏洞的准确率以及精度。 https://github.com/LoRexxar/Kunlun-M/tree/cobra-w
Kunlun-Mirror是从Cobra-W2.0发展而来，在经历了痛苦的维护改进原工具之后，昆仑镜将工具的发展重心放在安全研究员的使用上，将会围绕工具化使用不断改进使用体验。
目前工具主要支持php、javascript的语义分析，以及chrome ext, solidity的基础扫描.
KunLun-M(昆仑镜)已进入弱维护阶段，如果有bug或者明显的问题会更新，但不会再更新新功能，主要是我认为Kunlun-M的架构拖累了后续的发展方向，仅在PHP扫描中以当前的架构已经几乎做到极限了，后续可能会有新的工具？也可能没有？敬请期待~
请使用python3.6+运行该工具，已停止维护python2.7环境
二、特点
与其他代码审计相比：
-
静态分析，环境依赖小。
-
语义分析，对漏洞有效性判断程度更深。
-
多种语言支持。
-
开源python实现，更易于二次开发。
与Cobra相比：
-
深度重写AST，大幅度减少漏洞误报率。
-
底层api重写，支持windows、linux等多平台。
-
多层语义解析、函数回溯，secret机制，新增多种机制应用于语义分析。
-
新增javascript语义分析，用于扫描包含js相关代码。
与Cobra-W相比(todo):
-
深度优化AST分析流程，使其更符合QL的概念，便于下一阶段的优化。
-
深度优化辅助审计的流程，使其更符合人类安全研究员审计辅助的习惯。
-
深度重构代码结构，使其更符合可拓展，可优化的开源理念。
