File Carving科普
我们今天将给大家带来取证相关的内容，这里首先要说到一个单词就是File Carving，很多机器翻译都把这个Carving翻译成雕刻，文件雕刻是什么鬼？我们这里可以看到《File carving》文中给出的定义：
File carving is a process used in computer forensics to extract data from a disk drive or other storage device without the assistance of the file system that originality created the file.
我们可以理解为File carving其实就是提取文件信息，但是它是一个名词，因此翻译的时候就可以翻译成文件信息提取
视频介绍
本视频我们将带大家熟悉常见的文件取证工具，针对图片可以使用file、exiftools、bindwalk、strings、hexeditor等工具进行分析，同时我们还将教大家如何通过管道配合grep、cut、tr等命令完成对最终目标的提取。
