Description
This image passes LSB statistical analysis, but we can't help but think there must be something to the visual artifacts present in this image...
Download the image [here]


This type of challenge can be easily solved with StegSolve because this site can extract LSB data with pixel order and RGB values. or by using this github repo may help you

and using python sigBits.py -t=msb -o=rgb -e=column file.png

I tried the first default option -> the first row in this site and got readable words, so I downloaded the whole using sigbits go in the extracted file and CTRL+F the word pico both ways work I found the flag:

picoCTF{your flag}
