iPhone Hack Makes Your Apple Device Completely Vulnerable

August 3, 2010, By Radimir Bobev

A new security breach in the iOS 4 has just been discovered, and it affects the iPhone, iPod Touch, as well as the iPad. The exploit involves loading a malicious PDF document when visiting a specially crafted web page, and is so serious that it actually opens up your entire device’s control to the hacker behind the website.

The exploit is tricky to explain simply without going into technical details – but basically, a piece of code is disguised as a custom font inside the PDF, and a bug causes the iOS to actually execute this code – which can then lead to some serious consequences for the user of the device.

The exact application for this exploit is up to the person writing the “virus” to decide, but bear in mind that they can go as far as copying/deleting files from your phone’s system as well as logging your every click.

The safest way to deal with the problem so far is to install the “PDF loading warner” (you’ll have to jailbreak your iPhone for this though), which modifies your browser to ask you whether you want to load PDF files on every website you visit.
