A full list of phones is presently being generated but it appears as though most things with Galaxy in the name need to be careful. The exploit itself appears to be quite simple and the result of a mismatch between different security systems (web browser being able to interact with the far reaching USSD codes system) rather than a more elaborate hack although it is still just as potent to that capable of being hit by it.
It is still very early days so there will be more information coming out over the coming hours and days.

Suffice it to say any sharing of potentially damaging urls will be dealt with severely. If you are curious the source below links to a test page that will see your IMEI number displayed if you are vulnerable, you can visit the test site at http://dylanreeve.com/phone.php
