Millions of iPhone users have been urged to update their devices to iOS 18 as soon as possible to fix a bug that allows hackers to steal their data. The vulnerability affects the Transparency, Consent and Control (TCC) subsystem in iOS, which is responsible for notifying users when an app tries to access sensitive data such as photos, GPS location, contacts and more.

But the bug causes this notification system to fail, potentially allowing third parties to steal 'extensive' amounts of iCloud data through your apps. This type of vulnerability is known as a 'TCC bypass.'. 'Alarmingly, this exploitation occurs without leaving any trace of the data accessed, posing a threat to user privacy and overall data security,' cybersecurity experts stated.
The bug was discovered by the cybersecurity firm Jamf Threat Labs, which found that it affects both iPhones and Macs. Jamf experts reported their findings to Apple, and the tech company patched the issue in iOS 18 and macOS 15 - the latest versions of the iPhone and Mac operating systems.
Jamf's warning comes as Apple prepares to launch iOS 18.2 - the latest update to their operating system. Millions of iPhone users have been urged to update their devices as soon as possible to fix a bug that allows hackers to steal their data. The first version of iOS 18 launched on September 16 to dozens of devices.
