Download and read what is inside this file:

curl https://artifacts.picoctf.net/c/475/enc_flag -o enc_flag

ls

cat enc_flag

It seems to be base64 encoded, lets decoded using a utility in kali linux called base64:

cat enc_flag | base64 -d

• -d: To decode that string.

Another base64, and after multiple decodes:

cat enc_flag | base64 -d | base64 -d | base64 -d | base64 -d | base64 -d | base64 -d

Here is the flag.
