前言：
最近正在写自动化的扫描器，但是老是容易过快被ban，代理ip和分布式成本可能也比较高 或者出现
不稳定（都是假的，只是因为我是学生，没收入，买不起服务器）
那么如何优化现有的扫描过程，即不降低速度 又不给ban呢。
我把这个扫描 叫 华莱士喷射目录扫描。
原来的扫描过程：
华莱士喷射扫描
title: 目录扫描的小tips
就是把扫描顺序改变。这样子目标越多的情况下，同一个域名的扫描间隔时间越长，被ban的可能性也
越低。但是效率不会降低。
在这个基础上 再加上分布式，多线程，随机代理等方法 更加稳健。
工具
找了一圈没找到想要的这样子的工具，同时又比较喜爱dirsearch。一开始想魔改dirsearch的，但是他... | pdf |

一、判断是否在docker容器里
首先，我们需要先判断是否在docker环境里，常用的两个检测方式：
目前来说，这两种检测方式还是比较有效的，其他检测方式，如检测mount、fdisk -l查看硬盘 、判断PID 1的进程名
等也可用来辅助判断。
二、配置不当引发的docker逃逸
2.1 docker remote api未授权访问
漏洞简述：docker remote api可以执行docker命令，docker守护进程监听在0.0.0.0，可直接调用API来操作
docker。
通过docker daemon api 执行docker命令。

通过在进程级别操纵环境变量，可以让受信任的应⽤程序加载任意 DLL 并执⾏恶意代
码。这篇⽂章列出了近 100 个在 Windows 11 (21H2) 上易受此类 DLL 劫持的可执⾏⽂

环境变量
环境变量是在 1970 年代后期在 Unix V7 [ 1 , p.99-101 ] 中引⼊的，作为将信息传递给进程的
⼀种简单⽅法。事实证明它很受欢迎：⼏年后它也被 PC DOS 2.0 [ 2 , p.477 ] 采⽤，最终演
