Flag

Given files
- script.jpg
The file is corrupted, by extend gitlab doesn't want to upload it as
.jpg.
How the challenge works
The image is actually a docx-file. The file signature has been replaced by X's, because of this it won't open in any way (invalid hex file). The most conventional way to solve is as following:
- remove
X's from the file - apply
strings(now you see it is a docx-file) - find file signature online:
50 4B 03 04 14 00 06 00 - set file signature, open in Word/Writer
- flag is in image on last page of the file
