Extract metadata from file in Backtrack

Metadata is stored in any document by authoring application which can be user-name ; comment ;creation date;modification date.Metadata is very important in computer Forensic ; well know hacker group Anonymous `s members are arrested due to metadata. Because they upload document without clearing metadata ; so by reading metadata we can find lots of juicy information.


Previous we saw how we can extract metadata using FOCA from website ; But we can also extract metadata from BACKTRACK using exiftool.

If you want to write your own python script then visit our new section of blog script .

Exiftool can extract metadata from images ;documents ,videos etc.Most of file format are supported in exiftool. EXIFTOOL can also write metadata into Documents. So before uploading document remove metadata from it
