A Vodafone server was recently hacked exposing over 2 million users accounts. The attack was detected at the beginning of September.
The hacker gained access to customers account information including names, addresses, birth dates, and bank account information. Vodafone, the world's second biggest mobile carrier, said the hacker did not gain access to cell phone numbers, credit card information, or customer PINs. It is believed that the hacker had insider knowledge on the systems in place.
This is one of the latest in a string of high profile hacking cases that have occurred in the last few months. Companies like Google, Twitter, and The NewYork Times have come under similar attacks.
