Vodafone Iceland’s servers were hacked on 30 November 2013. Hackers managed to steal confidential account information including customer names, email addresses, social security numbers, and SMS messages.
If you’re a Vodafone Iceland customer it’s a good idea to change your password. And if you’ve sent any confidential information via SMS (such as credit card details, passwords, etc) you should look into that as well.
This is a good time to remind everyone that SMS messages are not very private. Most phone companies keep all SMSs, usually for law enforcement reasons.
