## Description
I swear I didn't realize what I was naming it until I submitted the challenge
[glute.png](glute.png)
## Detailed solution
Start by checking some details about the file 
```file glute.png
glute.png: PNG image data, 699 x 699, 8-bit/color RGBA, non-interlaced``````exiftool glute.png
ExifTool Version Number         : 12.16File Name                       : glute.pngDirectory                       : .File Size                       : 335 KiBFile Modification Date/Time     : 2021:04:24 04:15:04+00:00File Access Date/Time           : 2021:04:24 04:15:04+00:00File Inode Change Date/Time     : 2021:04:26 03:46:11+00:00File Permissions                : rw-r--r--File Type                       : PNGFile Type Extension             : pngMIME Type                       : image/pngImage Width                     : 699Image Height                    : 699Bit Depth                       : 8Color Type                      : RGB with AlphaCompression                     : Deflate/InflateFilter                          : AdaptiveInterlace                       : NoninterlacedImage Size                      : 699x699Megapixels                      : 0.489```
Checking strings in the image i found a PDF string ```%PDF-1.7``` which is the version of a PDF file
Let's run **binwalk** to check for embedded files  
```binwalk glute.png

Let's extract all files 
```binwalk -e --dd='.*' glute.png

We can see multiple files let's check them
We can see our flag in the pdf file 45BEA
