The flag will appear when connecting to the server but will be encoded in base64.

Connections

This is a simple network encoding challenge. According to the description, when you connect to the server, the flag will be sent in base64 encoding.

Connect to the server to receive the flag, which will be displayed in base64 encoding:

$ nc nct25.thehackerconclave.es 26023
Y29uY2xhdmV7NGU5ZmZhZDQ0NWEzZDc1YmIwZjRjY2UyNDNlYWQ4YzJ9Cg==

Now, let’s decode it using the base64 utility:

$ echo Y29uY2xhdmV7NGU5ZmZhZDQ0NWEzZDc1YmIwZjRjY2UyNDNlYWQ4YzJ9Cg== | base64 -d
conclave{4e9ffad445a3d75bb0f4cce243ead8c2}
