Xor Grant Challenge (2024)

There’s a secret message hidden in the image above with the following pattern:

___flag{$SECRET_MESSAGE}___

; where $SECRET_MESSAGE := [a-z0-9_]+

For example, if you have extracted “___flag{hello_w0rld}___”, the $SECRET_MESSAGE is the “hello_w0rld” part. In your application, please provide the $SECRET_MESSAGE and optionally your solution implementation or writeup for the full credit.
