“Want to invisibly spy on 10 iPhone owners without their knowledge? Gather their every keystroke, sound, message and location? That will cost you $650,000, plus a $500,000 setup fee with an Israeli outfit called the NSO Group. You can spy on more people if you would like — just check out the company’s price list.
The NSO Group is one of a number of companies that sell surveillance tools that can capture all the activity on a smartphone, like a user’s location and personal contacts. These tools can even turn the phone into a secret recording device.”
