My friend said they hid a flag in this picture, but it's broken!

This problem is the last one for the beginner. I downloaded the secret.jpg file, however, I couldn't open it. I just got "file cannot be readable" error message. So I checked the file type on linux environment (Actually, I use WSL, Windows Subsystem for Linux). And then, I found out the file's extension is faked.
$ file secret.jpg secret.jpg: ASCII text
$ strings secret.jpg utflag{d0nt_tru5t_f1l3_3xt3ns10n5}
Flag : utflag{d0nt_tru5t_f1l3_3xt3ns10n5}
