这本来只是是我写的⼯具⾥⾯⼀个插件 后⾯那个⼯具bug太多就没有维护了，有⼀个需求就把这个插件摘出来改

需求是拿到域内控制器的权限，但是要定位域内⽤户的ip，找了市⾯上的⼯具基本都是扔到域控上去执⾏，在域控

从FireEye的泄露看红队的差距
1. 前言
一大早被领导拉起来分析火眼事件。朋友圈整个安全圈子也是沸腾不已，但随着分析的深入，发现有
点“小题大做”了，没有想要的高尖精工具和技术方案，全是一堆已知攻击技术的红队模拟工具。但站在
一个红队人员的角度，也是收获不少。
2. 红队服务真的有用“假想敌手段”么？
以“假想敌”手段来评估企业安全，这里的手段往往被定义为APT手段。国内当前的红队服务使用的手段是
APT手段么？什么是APT手段？红队是怎么模拟的？
在火眼给的防御策略中，明显看出APT开头的很多样本、工具、后门。火眼的安全人员把各项在APT活动
中的技术方法做成了红队工具，用来评估企业对各种APT技术的防御能力，至少从工具层面... | pdf |

微擎 CMS：从 SQL 到 RCE

微擎 CMS 在 2.0 版本的时候悄咪咪修复了⼀处 SQL 注⼊漏洞：
api.php 536 ⾏
该处的注⼊漏洞⽹上没有出现过分析⽂章，因此本⽂就来分析⼀下该处 SQL 注⼊的利⽤。
0x02 影响版本
经过测试发现，官⽹在 GitLee 上，在 v1.5.2 存在此漏洞，在 2.0 版本修复了该漏洞，因此
⽬测⾄少影响到 v1.5.2 版本

这个注⼊漏洞分析还是⽐较简单的，直接定位到存在漏洞的代码处 api.php 530 ⾏开始、
