While I do agree that a mid/low-level employee is very unlikely to be the cause (why risk a reasonably high salary at Uber and possibly being blackballed from the industry if detected?), I think Hanlon's Razor [1] could be used here to infer that it was more likely a breach of Uber's systems.

Hanlon's razor tends not to hold true when malice is profitable, and ignorance is a conveniently plausible excuse.

Hanlon's Razor is a social policy for harmonious judgments on individuals. Uber is a company out to make money and there's no need to extend such a courtesy to them.
