面具下的flag

知识点

vmdk

binwalk

解题

打开照片,查看详细信息,没有什么东西

010editor查看一下

image-20231125164007319

发现有文件拼接

binwalk分离一下,有一个flag.vmdk

但是还是看看压缩包先

压缩包有加密,先看看是不是伪加密

7-zip解压vmdk文件

7z x flag.vmdk -o./

发现文件列表为

┌──(c㉿ex)-[~/Desktop/fla]

key_part_two/where_is_flag_part_two.txt:flag_part_two_is_here.txt

ook解密后为
