Warning! Your iPhone Can Get Hacked Just by Opening a JPEG Image, PDF or Font File

October 25, 2016Mohit Kumar
What's worse than knowing that innocent looking JPEGs, PDFs and font files can hijack your iPhone, iPad, and iPod. Yes, attackers can take over your vulnerable Apple's iOS device remotely – all they have to do is trick you to view a maliciously-crafted JPEG graphic or PDF file through a website or an email, which could allow them to execute malicious code on your system. That's a terrible flaw (CVE-2016-4673), but the good news is that Apple has released the latest version of its mobile operating system, iOS 10.1 , for iPhones and iPads to address this remote-code execution flaw, alongside an array of bug fixes. And now that the company has rolled out a security patch, some hackers would surely find vulnerable Apple devices to exploit the vulnerability and take full control of them. So, users running older versions of iOS are advised to update their mobile devices to iOS 10.1 as soon as possible. Besides this remote code execution flaw, the newest iOS 10.1 incl
