Panasonic

2. 智能冰箱的型号?【标准格式:MiFridge2024】 What is the model of the smart refrigerator? [Answer format: MiFridge2024]

3. 冰箱的uuid?【标准格式:34567890-12cd-efab-3456-789012cdefab】 Find the UUID of the smart refrigerator. [Answer format: 34567890-12cd-efab-3456-789012cdefab]

这个我当时是没找到的,心细一点应该能看到其实这一行的格式和他提供的格式非常之像

12345678-90ab-cdef-1234-567890abcdef

4. 冰箱默认保存几张图片?【标准格式:1】 How many images are saved by default in the smart refrigerator? [Answer format: 1]

原本用~~binwalk -e bx.bin~~但是一直没有办法提取出来文件,后来在网上看到可以用 ~~`binwalk –dd=”.*” bx.bin`就成功提取了,这是提取的结果~~这个办法也不行,因为他会提取文件的同时把剩下的不要的二进制一起放在最后一个文件里面

用foremost,命令:foremost -T file,这里用的是foremost -T bx.bin

这里甚至做好了分类,当然binwalk也可以用

当时是只看到了4张照片于是乎就填了4,但是其实应该敏感点的:

看二进制文件每一张照片之前都有face1、face2等等

然后搜索到最多有face5

这里其实暴露了我应该看完案情之后再做题,谁是嫌疑人我真不知道,但是当时猜了一下(四张图片三张都是贾韦码,所以选了另外一个钟无声)

882564

9. 请找出冰箱最后一次开门时间?【标准格式:10:11】 When was the refrigerator last opened? [Answer format: 10:11]

不知道不知道不知道网上也没找到答案
