web20（mbd文件）
萌新隐写5
那我们访问editor,出现如下页面
在图片里面找到fl000g.txt,放在网址中访问
右下角看到邮箱
访问admin看到这个页面，将邮箱输入密码显示错误。那就点忘记密码。忘记密码里面需要用所在地，那就用QQ查看，将所在地提交即可
网址后访问tz.php，这里点入
ctrl+f搜索flag
网址后输入backup.sql
无法直接打开源代码，ctrl+u
点击js一个个搜寻，在最下面js里面发现uncode编码
解出来后是一堆汉字，读出来就好了。访问110.php
注意是Post,
,
抓包后发现pazzword里的密码和原先不一样，应该是加密所致，改成原先密码出flag
对AES理解:注意是AES/CBC/...
源代码里出现了密钥和偏移量
mdb文件是早期asp+access构架的数据库文件，文件泄露相当于数据库被脱裤了。
直接查看url路径添加/db/db.mdb 下载文件通过txt打开
FBI大写，试着找找大写文件。这里我想复习一下正则表达式
import re
string = 'i was always Fond of visiting new scenes, and observing strange characters and manners. even when a mere chiLd i began my travels, and made mAny tours of discovery into foreiGn {parts and unknown regions of my native City, to the frequent alarm of my parents, and The emolument of the town-crier. as i grew into boyhood, i extended the range oF my obServations. my holiday afternoons were spent in rambles about tHe surrounding cOuntry. i made myself familiar With all its places famous in history or fable. i kNew every spot where a murder or robbery had been committed, or a ghost seen. i visited the neighboring villages, and added greatly to my stock of knowledge,By noting their habits and customs, and conversing with their sages and great men.}'
result = ''.join(re.findall(r'[A-Z\{A-Z\}]', string))
print(result)正则表达式还是要多多练习啊
根据题目判断是zip伪加密.再复习一遍伪加密
00 00：全局方式位标记（有无加密，这个更改这里进行伪加密，改为09 00打开就会提示有密码了
有点儿意思
借助大佬脚本算图片正确宽高
import struct
import binascii
import os
m = open("D:/flag.png","rb").read()
k=0
for i in range(5000):
if k==1:
break
for j in range(5000):
c = m[12:16] + struct.pack('>i', i) + struct.pack('>i', j)+m[24:29]
crc = binascii.crc32(c) & 0xffffffff
if crc == 0x889C2F07:
k = 1
print(hex(i),hex(j))
break
crc:
故技重施
这图小时候都玩烂了
保存下来看010editor发现是个png后缀，改掉后缀后是二维码，扫描得网址。网址放上去没结果。
因为最后是=结尾，看base64编码，得flag
将图片保存到本地，修改文件头
将图片保存本地,下载jphs打开文件，点击seek，保存。打开是flag
这题保存本地，将文中汉字用uncode编码转义，然后再转成ascii码，在笔记本去掉\u
最后用base32转义得flag
