Some iPhone, iPad, and Mac users in Australia are waking up to ransom messages declaring that their devices have been hacked. Device hacked by Oleg Pliss, reads one message on an iMac, and others have received notices demanding a $50 PayPal payment to unlock an iPhone. While some who have experienced the unusual attack have been able to unlock their devices, others are seeking help from Apple and carriers to regain access to their phones. It’s not immediately clear how pranksters are gaining access to the Apple IDs to take over the devices, nor why the reports are localized to Australia.
