Challenge Description
Maybe 0DAY?XD!!!!
Solution
This was the image that was given in the challenge, I tried to scan it with QR scanner but it was not showing any result.
After reading multiple article i find out about this web tool called QRAZYBOX.
LINK: https://merri.cx/qrazybox/
After some research i find out that this is a version 5 QR code. So after opening new project and selecting blank qr code i selected the version 5.
Next was selecting the mask, for this i just select every option and checks which mask is exact match, From which i identified that Mask L 2 was perfect match.
Then i start drawing the QR code here.
After this i clicked on tools and select “Extract QR Information”From which i got this binary
Just copied this binary and convert it to ascii from this website : https://www.binaryhexconverter.com/binary-to-ascii-text-converter
Here's the flag:
