The first step in any forensics challenge is to verify the file type and examine basic metadata.

: If you change the dimensions manually, the CRC (Cyclic Redundancy Check) at the end of the chunk will be invalid. You can use a tool like PCRT (PNG Check & Repair Tool) to automatically calculate the correct dimensions based on the existing CRC. 4. Steganography Check 2022-06-03 11-32-03~2.png

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 ). The first step in any forensics challenge is

: Use StegSolve to cycle through the color planes. Often, the flag is hidden in the Least Significant Bits (LSB) of the Red, Green, or Blue channels. Tool : Hex Editor (like HxD or hexedit )

: 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.

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.

If repairing the header doesn't reveal the flag, the next step is checking for hidden data:
