答案

flag{I_DONT_WANT_TO_DO_SO_MUCH_HOMEWORK_AAAAAAAA_BY_A_Y}

题解

第一步:凯撒移位

看到dinnzs.ozzsbmci.kobu里面几个点,第一反应应该是某个类似域名的东西吧。

再看提示里面的“中间那一段和秋实的常用ID相关”,知道中间一段对应的应该是秋实秋实-AllenyouAllenyou中的一个,结合长度推测是Allenyou

同时,提示中“想想秋实的博客是什么吧”也提示我们可能与这个博客的域名有关(allenyou.wang和后面的长度刚好对应),后面ozzsbmci.kobuallenyou.wang对应。

简单列一个字母表不难看出这是一个简单的凯撒移位,移位位数是14

解密后得到puzzle.allenyou.wang

第二步:DNS TXT Record

这是一个域名,但是扔进浏览器里打不开。

此时试着用nslookup查询一下DNS记录,发现是TXT类型记录,得到网址https://www.allenyou.wang/fuck/so/much/homework/puzzle.html

第三步:Base58

这里打开网址发现下面这些东西:

这种编码看起来很像Base系列编码,但是没有+,也没有0o这种字符,猜测是Base58[1],解码后得到下一步信息。

第四步:JSFuck

上一步解码得到的信息是:

这时候应该有人能猜出这是JSFuck[2]了,直接扔进任何一个能运行JavaScript的地方都行,得到666c61677b495f444f4e545f57414e545f544f5f444f5f534f5f4d5543485f484f4d45574f524b5f41414141414141415f42595f415f597d

第五步:Hex to Text

显然,这是一段十六进制的文本。

转换成文本就是答案flag{I_DONT_WANT_TO_DO_SO_MUCH_HOMEWORK_AAAAAAAA_BY_A_Y}

总结

其实这次出题只用了我不到一小时(汗),还出现了中途换题的尴尬,好在没有阻止DALAO们暴杀这道题。

可以看出,从Flag到题目里的网址全都体现着我对作业的喜爱怨念(笑)

这次总的来说难度还是比较低的,明年我会尽量给大家带来更有意思的谜题的。

最后还是祝大家新年快乐!
