JACTF web签到

首先查看源代码,发现3719372767312836781.js可能会有点东西。


<html>
<head>
	<title>签到title>
	<meta charset="utf-8">
	<script type="text/javascript" src="./3719372767312836781.js">script>
head>
<body>
<h1>Not Foundh1>
<p>The requested URL /eighteen8.php was not found on this server.p>
<p>Additionally, a 404 Not Found

呀,小伙子不错啊,还可以找到这里,是个人才。

but,flag不在这里,不过还是在这个页面内,你自己看一看。
p>

html>

点开看看,

String.fromCharCode(102,108,97,103,58,102,108,97,103,95,105,115,95,118,101,114,121,95,101,97,115,121)

很明显102是“f"的ASCII码,于是用python编写一个脚本,

# coding=utf-8
#--author:valecalida--
 
s = [102,108,97,103,58,102,108,97,103,95,105,115,95,118,101,114,121,95,101,97,115,121]
flag = ''
for i in s:
    k = chr(i)
    flag += k
print("web签到的flag是",flag)

得到flag:flag_is_very_easy
