 题目三：文件恢复

小明以为文件删除了别人就看不到了。too young too simple呀

下载的文件file一下 Linux rev 1.0 ext3 filesystem data,

百度知道是ext3文件的恢复，我也不懂

关于一道ext3文件处理的misc题_浮岚丶暖阳的博客-CSDN博客

有个类似的这个题比上面博客的简单会用 extundelete就行

恢复出一个flag.txt 

题目四：病毒文件恢复

 附件有一个txt还有一个乱七八糟的后缀

查看说明英文翻译就是想要查看内容需要支付抽紧

利用360可以在线解密安全卫士勒索病毒专题:文件恢复_安全卫士离线救灾版_文档卫士

 得到flag

题目五：血小板天下第一可爱

解题思路 ps二维码得到一串密文像base64尝试解密
