Apple Execs Chose to Keep a Hack of 128 Million iPhones Quiet
The mass hack first came to light when researchers uncovered 40 malicious App Store apps, a number that mushroomed to 4,000 as more researchers poked around. The apps contained code that made iPhones and iPads part of a botnet that stole potentially sensitive user information.
On the afternoon of September 21, 2015, Apple managers had uncovered 2,500 malicious apps that had been downloaded a total of 203 million times by 128 million users, 18 million of whom were in the US. But the company never directly notified affected users.
