Solution:
The given website has a file upload form. The challenge title mentions archives. If we search on Google, we find that common file extensions for archives include TIFF, RAW, etc.

The abbreviation of the challenge title might lead solvers to think of the RAW file extension, but that is a false lead. Instead, solvers must upload a TIFF file (under 5 MB in size) to trigger an alert containing the flag.
