The provided link had a input link with js code on the input field.

• The code:

        javascript:(function() {
            var encryptedFlag = "àÒÆަȬëÙ£Ö�ÓÚåÛÑ¢ÕÓ�Ó�Ç¡�¥Ìí";
            var key = "picoctf";
            var decryptedFlag = "";
            for (var i = 0; i < encryptedFlag.length; i++) {
                decryptedFlag += String.fromCharCode((encryptedFlag.charCodeAt(i) - key.charCodeAt(i % key.length) + 256) % 256);
            }
            alert(decryptedFlag);
        })();

Running that code on the console of the browser gives the flag on alert window.
