There was some iPhone spying app that got hacked a year or two ago. I cannot remember what the name was, but if anyone remembers it, please post it here. It was a semi-public leak, and there was a dedicated hidden service that had it up for download. The service went down fairly fast though, I think within 24-36 hours. Luckily, I had grabbed it.
EDIT: This is the mSpy app.
The problem with the leak was that it was a huge tarball, upwards of 40GB if I remember correctly, and the accounts were inside of access logs stored throughout ~300 BSON files (I have no idea why you would store access logs in a NoSQL database). I parsed the access logs throughout the many files though, and I ended up getting nearly 1.6 million accounts. Unfortunately, about 25-50% of the lines in this file are duplicates, and I am too lazy to remove them lol. Still, there is ~1 million unique accounts.
Sorry, but you need at least 25 posts and 5 hours online time to unlock hidden content.
