Along these lines, I remember a program back in ~2006 that would allow you to download songs from other machines on a LAN network if they had iTunes open. Something about iTunes defaulting to sharing libraries on the network.
As someone in college at the time, this felt like a music goldmine. I remember running the program over night and downloading thousands of songs from other machines on campus. And while I was going to say I can't remember the name of it, I just fell down a rabbit hole of Google searches and found it, ourTunes!
In my specific case they sent over an amount to repay that was higher than what I calculated from my original contract, I asked for an itemized breakdown (the original communication just had a single flat number), and I never heard from them again. It was probably more expensive for their lawyers to double check the numbers than the amount they would have received from me.
When I got hired to work at Wizards of the Coast (no longer there), the contract I signed said I would have to pay back my signing bonus if I left within one year, and 50% of my relocation package if I left before 2 years.
The one thing that often gets difficult with these things is that you get charged tax on the signing bonus (as additional income), but when you are required to pay it back you're expected to pay the full amount pre-tax.
