前 言
《Java 开发手册》是阿里巴巴集团技术团队的集体智慧结晶和经验总结，经历了多次大规模
一线实战的检验及不断完善，公开到业界后，众多社区开发者踊跃参与，共同打磨完善，系统化地
整理成册。现代软件行业的高速发展对开发者的综合素质要求越来越高，因为不仅是编程知识点，
其它维度的知识点也会影响到软件的最终交付质量。比如：数据库的表结构和索引设计缺陷可能带
来软件上的架构缺陷或性能风险；工程结构混乱导致后续维护艰难；没有鉴权的漏洞代码易被黑客
攻击等等。所以本手册以 Java 开发者为中心视角，划分为编程规约、异常日志、单元测试、安全规
约、MySQL 数据库、工程结构、设计规约七个维度，再根据内容特征，细分成若干二级子目录。

java反序列化基础知识总结
java的类加载过程
1. 首先是调用 public Class<?> loadClass(String name) 方法，通过public方法调用保护方法
protected Class<?> loadClass(String name, boolean resolve)
2. 在 protected loadClass 方法中，第400行会调用一个 findLoadedClass 方法判断当前类是否已
经加载。如果类已经加载，直接返回当前类的类对象。
3. 如果创建当前 ClassLoader 时传入了父类加载器( new ClassLoader (父类加载器))就使用父类加载

[+] Author: math1as

#1 引言
在目前的web安全漏洞中,xss一直属于热门的一类,而它对用户造成的危害较大。
因此也引发了不少安全爱好者和专业工程师的研究。
而html5等新技术的使用和具体业务场景中复杂的环境带给了xss更大的生存空间。
而且不同xss向量也因为浏览器的特性会有所区别
比如chrome在加载资源时会校验服务器返回的mimeType
而firefox则根据标签自己设定的type来做出处理
本文在目前较为常见的几种过滤条件下,简单的探讨了xss这一技术的应用以及绕过

最近在研究关于聊天软件的一些信息获取。
对于微信来说获取个人信息就是读取内存中的字符串，这些字符包括电话、数据库key、username、
wxid等等，但是微信不同的版本字符串在内存中的位置不一样，也就是偏移不一样，看之前的 BIOPASS
RAT ,它的微信模块定位使用版本号，不同版本号的偏移不一样。
艹老师说这种方式太麻烦了，微信每更新一个版本就得更新偏移。于是，我研究了根据微信特定数据结
构定位的方式，这种方式可以全版本通用。

因为我的主要目的是获取数据库的key，通过看雪的这篇文章

命令执行无回显的判断方法及 dnslog 相关例题
一、命令执行判断
命令执行可能会存在命令执行完没有回显，首先要判断命令
是否有执行，可以通过三种方式来判断：延时、HTTP 请求、
DNS 请求。
1、
延时：
无延时无回显
有延时无回显
通过是否延时来判断该条命令是否有执行，有延时则代表命
令有执行。（”sleep 3”表示延时 3 秒）
2、
HTTP 请求：目标机通过向公网可通信的机子发起 http
请求，而这个公网可通信的机子是我们可控的，则当该公
网机子收到 http 请求就代表命令有执行。
例：我们在公网机上可以通过”nc -lv 端口号”来监听该端口，
当目标机”curl 公网机 ip:端口号”的时候，公网机的该端口... | pdf |
1. 前言
昨晚看到朋友圈推了个和裸聊诈骗斗智斗勇的视频，点进去一看感觉和上个月搞得一个站的后台很像，
所以想上去看一下，结果网站关了，就通过fofa重新搜了一个存活的网站，发现确实很像。
于是就有了这篇文章，由于很多都是后补的图，可能不是很完整，见谅。
2. 第一次shell
由于上次拿到目标的时候就给了一个域名，所以先浏览一下看看，常规的扫一下目录。
发现存在 uploads , temp , tmp 这几个看起来很像上传文件的目录，而且有 file.php 这个文件，然后发
现扫出很多奇奇怪怪的东西，猜测对应目录nginx应该是设置了php禁止执行。
