解压出来的压缩包中有一个没有后缀名的文件，用010打开
zip的文件头，改成zip文件，解压
里面是个class文件，用记事本打开
疑似凯撒，解密得到flag
HECTF{We1c0me_T0_H3ct6_!}
捉迷藏
解压文件得到一个word文档，打开没发现什么东西，改成zip格式后查看\\word\\document.xml文件，发现大量jsfuck密文
都复制下来，解密
HECTF{dfdfj234kflfj3fadfdsv}
迷途的狗狗
下载文件并解压后得到两个文件
压缩包加密，直接爆破提示版本号出错
拖进010里面修改版本号，修改0
之后用WinRar修复压缩包，再直接爆破
得到密码142345
之后分离图片，得到flag
HECTF{祝各位师傅玩的开心，期待HECTF2022您的到来}
snake
拿到发现是个exe文件 看logo可以猜测是pyistaller打包之后的exe
提取下py文件
修复一下snake的文件结构
修复完后的snake是pyc文件 转成py文件
查看源码
