RADARCTF - QRadar(Misc 400)

I found the broken?? QR codes, but it can't read by my iPhone.

Maybe it should be repaired.

I reffered the structure of QR code , and I think

->Timing patterns, Alignment patterns are correct.

-> About Version information and Format information, I can't understand well...

-> So I guess, only Position patterns are missing.

I should prepare the image of Position patterns which match to this QR code.

I used this site.

https://www.cman.jp/QRcode/qr_option/version/

By using this site, I can prepare the sample of QR code which according to the standard of each version.

I think "Version 11(61cells x 61 cells)" is most suitable for this QR code.

So I copy the Position patterns image from the QR code which make at above site,

and paste it to the original image.

Successful reading of QR code, I got the flag.

flag is: radar{qr_fixing_i5_v3ry_aw3s0me}

May be I think there is more stylish solution , but I didn't have the enough time to think it :P
