I don't know that I have seen leak be adopted over a more suitable term a la jailbreak thus far.
A leak to me still means some dev, security firm, press type given a copy, third party vetting deal, web admin, trusted party... fumbled the handling of sensitive data and allowed it to be accessed by those that they would rather not.
If someone rocks up to a shop, buys a game disc, takes it home, rips the disc and then shares it with the world that is not a leak. Someone snaffling a copy from a pressing plant might qualify as a leak but barely.
Now if we want to talk odd terms being adopted then datamining... most things I see described as such are anything but what I would see anybody going to school for datamining or being employed in industry as dataminers be doing. I would not be surprised at all to find a bunch of dataminers out there to be capable of doing something in this realm (many will have at least token programming skills and maybe would have had to sort binary data from a random database format or sensor and it is not a huge leap to most ROM hacking from there) but at the same time I would never expect to find it on any course or 99% of job postings/requirements -- I would usually see a dataminer as a statistician that knows how to work a database or three and maybe some light machine learning these days. Wonderful skill to have (
