When you perform a remote hard drive wipe on Find my Mac, the system asks you to create a four-digit PIN so that the process can be reversed. But here’s the thing: If someone else performs that wipe — someone who gained access to your iCloud account through malicious means — there’s no way for you to enter that PIN.
That sounds more like remote encryption to me. And a four digit PIN is easy to brute force (assuming that it isn't asking apple for the decryption key once entered (which means you need internet access do reverse it)).
