ELI5:The Sony leak: How did hackers manage to transfer 100TB of data out of Sony without being noticed?

Maybe I'm missing something, but my employer doesn't have nearly the amount of money or resources that Sony has, and as far as I know we're not a target for corporate espionage.  Still, if you do anything wonky on the network (upload/download large amounts of data, visit NSFW sites, etc...) you will get a visit from the IS department.

How did hackers manage to transfer 100TB of data out of Sony's network without anyone stopping them?

Sony has over 140,000 employees spread out across 10+ countries (who knows how many different offices?).. and they probably routinely transmit large amounts of data because of all the Movies that are constantly in production. 100TB is probably "chump change" for network-transfers when you're working on big movies that have lots of special effects and CGI and data being transferred between different Contractors or production-houses,etc.
