Stark’s Hidden Protocol

Challenge Description

Tony Stark left something behind…

During a routine forensic acquisition, we recovered a file named ironman.jpg from a suspect machine.

The image opens without issue and appears completely normal. However, analysts noticed that the file size doesn’t quite match what we would expect from a typical image of this resolution.

Nothing malicious was detected during automated scanning, but we suspect there may be more to this file than meets the eye.

Conduct a proper forensic analysis of the file and determine whether anything unusual is present.

Can you uncover what Stark didn’t want others to see?
