This challenge was a broken QR code needed to be recreated to be read.

### Process - SM

1. We're given an `xcf` file which is a GIMP project file.
`http://static.ctf.umasscybersec.org/misc/8e0111c9-d8d0-4518-973d-dbdcbd9d5a42/scan_me.xcf`
1. Opening the project in GIMP we can see there are two layers. Removing the top layer exposes the QR code.
1. If we fix the missing corner for the QR code to help the camera align the data.
1. The QR code gives us a URL [to an image](https://imgur.com/a/57VgQ8M) container our flag, `UMASS{RQ-3Z-m0d3}`.
