> The warning affects iPhone, iPad and Mac users and urges updates, along with caution around unfamiliar apps and links.

A vulnerability in Apple software versions released before iOS 27 was used to steal crypto wallets from some iPhone users, creating a security risk for holders who have not updated their devices, SlowMist's Cos warned.

The warning also covers iPads and Macs running older software. Users were urged to install the latest available updates across their Apple devices.

The security guidance included avoiding apps from unfamiliar sources and exercising caution when opening unknown links through Safari or browsers built into other apps. The warning did not identify the affected vulnerability or provide figures on the number of victims or the value of assets stolen.

Users with older Apple software should update their devices and review how they open apps and links.
