Linux 全盘加密
看了橙子酱大佬的加密分区解密让我想起了我之前做过 Linux 的全盘加密。
特此分享一下思路。。。。
1. 首先安装系统选择 /（根）分区加密。
就 3 个分区。一个 swap 一个 boot 一个根分区（加密，密码自定义）
其余都正常安装，就拿 centos6.9 举例。
2.进入系统，打开/usr/share/dracut/modules.d/90crypt/目录（看了说明文档找到的）
修改 cryptroot-ask.sh
把 108-112 行加上“#”注释，然后增加一行(如图)

今天遇到⼀个有意思的Linux命令执⾏绕过分享⼀下。
某⽹络设备后台有个Ping功能，命令执⾏⽆回显，使⽤
dnslog收到请求，因此icmp、dns出⽹。
但是进⼀步命令执⾏的时候发现存在很多替换为空的过滤。
第⼀步绕过，cp命令读取源码。
ping.php中存在参数过滤函数，并且使⽤ exec() 命令执⾏因此⽆回显。
根据include包含的⽂件必然能找到过滤函数所在的⽂件。
过滤如下
`whoami`.dnslog

php是⼀种解释型脚本语⾔.
与编译型语⾔不同,php源代码不是直接翻译成机器语⾔.⽽是翻译成中间代码(OPCODE) ,再由解释器
(ZEND引擎)对中间代码进⾏解释运⾏ .
在php源代码的保护在原理可以分为3⼤类.
源代码混淆(编码)
OPCODE混淆(编码)

某私有协议漏洞挖掘之旅
总结与建议
目录
智能设备中的私有协议
私有协议一般来说指未文档化的协议，格式未知，一般具有以下特点：
⚫ 从功能上来讲，一般用于运维管理/服务发现等功能
⚫ 一般监听于TCP/UDP的大端口
⚫ 多数作为服务端，部分可以在厂商官网找到协议的客户端
私有协议的格式未知，所以逆向分析较难，因此公开的漏洞较少，但... | pdf |

简单VS复杂
1.思考
1.1、利用工具简单：
数据包抓取工具（Burpsuit、fiddler等）
1.2、思路复杂：
核心：
绕过真实用户身份或正常业务流程达到预期的目的
1.2.1、用户身份：认证
用户身份特性认证
本地认证
服务器端认证
1.2.2、业务流程：对业务的熟悉程度（各种类
型的网站、业务模式）
电信网厅业务清单图解
2、逻辑漏洞类型
支付漏洞
密码找回漏洞
任意用户登录漏洞
认证缺陷（弱认证、认证凭证获取）

Java 代码审计常用漏洞总结
1.1 审计方法总结
主要代码审计方法是跟踪用户输入数据和敏感函数参数回溯：
跟踪用户的输入数据，判断数据进入的每一个代码逻辑是否有可利用的点，此处的代码逻辑
可以是一个函数，或者是条小小的条件判断语句。
敏感函数参数回溯，根据敏感函数，逆向追踪参数传递的过程。这个方法是最高效，最常用
的方法。大多数漏洞的产生是因为函数的使用不当导致的，只要找到这些函数，就能够快速
挖掘想要的漏洞。
以下是基于关键词审计技巧总结：
在搜索时要注意是否为整个单词,以及小写敏感这些设置

Windows 安全 - 服务篇（1）
0x00 前言
Windows安全范围真的很大，我也仅仅是在学习路上的行人。边学边记，在自己学习的同时，也希望有
一起的同行者。我计划从Windows服务开始，先学习windows服务的基础机制，然后再学习相关的安全
问题，然后记录这个过程中自己的一些思考，或延申性研究。这个过程中当然大量知识来自于网络公开
文献和《深入理解Windows操作系统7 》上下册。
Windows服务架构简图：
从简图看Windows服务的核心组件并不复杂，用户通常通过SCP类程序，例如：sc.exe等，来控制服务
应用。但是他并不是直接控制的，中间是通过SCM来控制的。
