The reported attack raised more questions than it answered.
For example, the report did not say how attackers managed to download terabytes of data before being discovered. A single terabyte can take up to several weeks to download over a relatively fast data connection, such as a Digital Subscriber Line or cable modem.
The report also suggested that China could be behind the stolen data, noting that investigators believe the attack originated in China. However, it said the exact identities of the people behind the attack had not been established.
... who could be anywhere in the world.
