Analysis
The provided file looked like a normal image at first glance.
To investigate further, I loaded it into steganalysis tools such as Aperi’Solve and stegonline
These platforms allow inspection of the individual bit planes (e.g., the least significant bits of each color channel).
Exploitation
By examining the red and blue channels at lower bit layers (e.g., Red 0, Red 1, Green 0, Blue 0), clear patterns appeared.
This pattern is the flag.
