: Locate the IHDR section (usually starts at offset 0x0C ). The four bytes following IHDR are the width, and the four after that are the height.
The most common solution for this specific file involves . Many CTF creators intentionally modify the height or width values in the PNG header so the image doesn't render correctly or hides the flag at the bottom. Tool : Hex Editor (like HxD or hexedit ).
Below is a technical write-up of the steps required to solve this challenge. 1. Initial File Analysis
: Use binwalk -e 2022-06-03 11-32-03~2.png to see if another file (like a .zip or .txt ) is embedded inside the image data. 5. Final Flag Extraction
The filename is associated with a common digital forensics challenge, often featured in Capture The Flag (CTF) events or forensics training modules. The goal of this specific challenge is typically to recover hidden data from a seemingly corrupted or standard image file.
: Run strings 2022-06-03 11-32-03~2.png . In many versions of this challenge, the flag or a hint is appended to the end of the file in plain text, past the IEND chunk.
