2EZ Writeup

Solved By : thewhiteh4t
- We are given a file named
2ez
- the file format is not known when I tested it with
file
command
- next I tried
binwalk
to look for any hidden files but the output was blank - next I checked the MAGIC of the file i.e. the header
- file magic is responsible for the correct file format
- file command checks magic and file footer to determine correct file type
- JFIF header means a jpeg file
- correct header for JFIF in hex is :
FF D8 FF
- but if we look at the file given to us its different, so I fixed it using a hex editor
- Saved it as a new file and solved
