导弹迷踪

一：题目信息

告诉是js代码，也就是数据都在前端

也就是告诉我们直接进去在源代码里找flag

二：窥探代码

直接在sources里面找线索，结果一下就找到了，本来还以为需要加密解密啥的。

成功找到flag

1zjs

一：题目信息

这里给了个提示jsfuck

jsfuck：

JSFuck是基于JavaScript原子部分的深奥和教育性编程风格。它仅仅使用六个不同的字符来编写和执行代码。

分别是：{ } [ ] + !

二：解题

看源代码，在源代码里面给了一个 flag.php文件访问

页面内容：

[+[]]]+(![]+[])[!+[]+!+[]]+(![]+[])[!+[]+!+[]]])[(![]+[])[!+[]+!+[]+!+[]]+(![]+[])[!+[]+!+[]]+([![]]+[][[]])[+!+[]+[+[]]]+([][(![]+[])[+[]]+([![]]+[][[]])[+!+[]+[+[]]]+(![]+[])[!+[]+!+[]]+(![]+[])[!+[]+!+[]]]+[])[!+[]+!+[]+!+[]]+(!![]+[])[!+[]+!+[]+!+[]]]((+((+(+!+[]+[+!+[]]+(!![]+[])[!+[]+!+[]+!+[]]+[!+[]+!+[]]+[+[]])+[])[+!+[]]+[+[]+[+[]]+[+[]]+[+[]]+[+[]]+[+[]]+[+[]]+[+[]]+[+[]]+[+!+[]]])+[])[!+[]+!+[]]+[+!+[]])+(![]+[])[+!+[]]+(!![]+[])[+[]]+(!![]+[])[!+[]+!+[]+!+[]])()())[!+[]+!+[]+!+[]+[+[]]]+(+[]+[][(![]+[])[+[]]+([![]]+[][[]])[+!+[]+[+[]]]+(![]+[])[!+[]+!+[]]+(![]+[])[!+[]+!+[]]][([][(![]+[])[+[]]+([![]]+[][[]])[+!+[]+[+[]]]+(![]+[])[!+[]+!+[]]+(![]+[])[!+[]+!+[]]]+[])[!+[]+!+[]+!+[]]+(!![]+[][(![]+[])[+[]]+([![]]+[][[]])[+!+[]+[+[]]]+(![]+[])[!+[]+!+[]]+(![]+[])[!+[]+!+[]]])[+!+[]+[+[]]]+([][[]]+[])[+!+[]]+(![]+[])[!+[]+!+[]+!+[]]+(!![]+[])[+[]]+(!![]+[])[+!+[]]+([][[]]+[])[+[]]+([][(![]+[])[+[]]+([![]]+[][[]])[+!+[]+[+[]]]+(![]+[])[!+[]+!+[]]+(![]+[])[!+[]+!+[]]]+[])[!+[]+!+[]+!+[]]+(!![]+[])[+[]]+(!![]+[][(![]+[])[+[]]+([![]]+[][[]])[+!+[]+[+[]]]+(![]+[])[!+[]+!+[]]+(![]+[])[!+[]+!+[]]])[+!+[]+[+[]]]+(!![]+[])[+!+[]]])[+!+[]+[+[]]]+(!![]+[][(![]+[])[+[]]+([![]]+[][[]])[+!+[]+[+[]]]+(![]+[])[!+[]+!+[]]+(![]+[])[!+[]+!+[]]])[!+[]+!+[]+[+[]]]+[!+[]+!+[]+!+[]+!+[]+!+[]+!+[]+!+[]]+[]+[!+[]+!+[]]+[]+[!+[]+!+[]+!+[]+!+[]+!+[]+!+[]+!+[]]+[]+(![]+[])[+!+[]]+([][(![]+[])[+[]]+([![]]+[][[]])[+!+[]+[+[]]]+(![]+[])[!+[]+!+[]]+(![]+[])[!+[]+!+[]]]+[])[!+[]+!+[]+!+[]]+([][(!![]+[])[!+[]+!+[]+!+[]]+([][[]]+[])[+!+[]]+(!![]+[])[+[]]+(!![]+[])[+!+[]]+([![]]+[][[]])[+!+[]+[+[]]]+(!![]+[])[!+[]+!+[]+!+[]]+(![]+[])[!+[]+!+[]+!+[]]]()+[])[!+[]+!+[]]+(![]+[])[+[]]+[+!+[]]+[]+(+((+(+!+[]+[+!+[]]+(!![]+[])[!+[]+!+[]+!+[]]+[!+[]+!+[]]+[+[]])+[])[+!+[]]+[+[]+[+[]]+[+[]]+[+[]]+[+[]]+[+[]]+[+[]]+[+[]]+[+[]]+[+!+[]]])+[])[!+[]+!+[]]+(!![]+[])[!+[]+!+[]+!+[]]+([][(![]+[])[+[]]+([![]]+[][[]])[+!+[]+[+[]]]+(![]+[])[!+[]+!+[]]+(![]+[])[!+[]+!+[]]]+[])[!+[]+!+[]+!+[]]+[!+[]+!+[]+!+[]+!+[]]+[]+[!+[]+!+[]+!+[]]+[]+(+((+(+!+[]+[+!+[]]+(!![]+[])[!+[]+!+[]+!+[]]+[!+[]+!+[]]+[+[]])+[])[+!+[]]+[+[]+[+[]]+[+[]]+[+[]]+[+[]]+[+[]]+[+[]]+[+[]]+[+[]]+[+!+[]]])+[])[!+[]+!+[]]+[!+[]+!+[]+!+[]+!+[]]+[]+[!+[]+!+[]+!+[]+!+[]+!+[]]+[]+[+!+[]]+[]+[!+[]+!+[]+!+[]+!+[]]+[]+(+((+(+!+[]+[+!+[]]+(!![]+[])[!+[]+!+[]+!+[]]+[!+[]+!+[]]+[+[]])+[])[+!+[]]+[+[]+[+[]]+[+[]]+[+[]]+[+[]]+[+[]]+[+[]]+[+[]]+[+[]]+[+!+[]]])+[])[!+[]+!+[]]+[!+[]+!+[]+!+[]+!+[]+!+[]+!+[]+!+[]+!+[]+!+[]]+[]+[!+[]+!+[]+!+[]+!+[]+!+[]+!+[]+!+[]]+[]+([][(!![]+[])[!+[]+!+[]+!+[]]+([][[]]+[])[+!+[]]+(!![]+[])[+[]]+(!![]+[])[+!+[]]+([![]]+[][[]])[+!+[]+[+[]]]+(!![]+[])[!+[]+!+[]+!+[]]+(![]+[])[!+[]+!+[]+!+[]]]()+[])[!+[]+!+[]]+(!![]+[])[!+[]+!+[]+!+[]]+(+((+(+!+[]+[+!+[]]+(!![]+[])[!+[]+!+[]+!+[]]+[!+[]+!+[]]+[+[]])+[])[+!+[]]+[+[]+[+[]]+[+[]]+[+[]]+[+[]]+[+[]]+[+[]]+[+[]]+[+[]]+[+!+[]]])+[])[!+[]+!+[]]+([][(![]+[])[+[]]+([![]]+[][[]])[+!+[]+[+[]]]+(![]+[])[!+[]+!+[]]+(![]+[])[!+[]+!+[]]]+[])[!+[]+!+[]+!+[]]+([][[]]+[])[!+[]+!+[]]+[!+[]+!+[]]+[]+(!![]+[])[!+[]+!+[]+!+[]]+[!+[]+!+[]]+[]+(![]+[])[+[]]+([][[]]+[])[!+[]+!+[]]+([][[]]+[])[!+[]+!+[]]+([][[]]+[])[!+[]+!+[]]+[+[]]+[]+(!![]+[])[!+[]+!+[]+!+[]]+[+[]]+[]+([][(![]+[])[+[]]+([![]]+[][[]])[+!+[]+[+[]]]+(![]+[])[!+[]+!+[]]+(![]+[])[!+[]+!+[]]]+[])[(![]+[])[!+[]+!+[]+!+[]]+(![]+[])[!+[]+!+[]]+([![]]+[][[]])[+!+[]+[+[]]]+([][(![]+[])[+[]]+([![]]+[][[]])[+!+[]+[+[]]]+(![]+[])[!+[]+!+[]]+(![]+[])[!+[]+!+[]]]+[])[!+[]+!+[]+!+[]]+(!![]+[])[!+[]+!+[]+!+[]]]((+((+(+!+[]+[+!+[]]+(!![]+[])[!+[]+!+[]+!+[]]+[!+[]+!+[]]+[+[]])+[])[+!+[]]+[+[]+[+[]]+[+[]]+[+[]]+[+[]]+[+[]]+[+[]]+[+[]]+[+[]]+[+!+[]]])+[])[!+[]+!+[]]+[+!+[]])

然后直接放到控制台运行一下就能得到flag。
