In my experience, the result of most hacks is a mix of technological prodding coupled with the collaboration from disgruntled insiders. Seldomly can a major hack by achieved without a combination of the above.
The most sought after hacks today are those that yield personal information like financial and health data. I figure WT does not keep massive amounts of the above and even if it did, those people don't have much money to steal.
With all that said, they key here, is that most businesses have no incentive to keep your data secure. Only as far as the expense is worth it. This has been seen time and time again. This assessment is not of my own making. I am paraphrasing a top security analyst.
The WT has plenty of free labor and tax free hardware and services to keep itself secure, fed by a mostly highly committed group of individuals who feel they are doing this work for a higher authority.
Would not be as easy. Getting a high level password is not even enough.
