Legally, it is hacking.

I remember a story about someone getting an absurdly long prison sentence for guessing a simple password to a secure system.

Hacking only specifies the knowing and intentional circumvention of an authorization system. It doesn't place a value on how easy it was to do it.

Years ago a teenager was arrested for "hacking" because he just Google'd the answers to Sarah Palin's security questions to gain access to her Yahoo account.
