More than 225,000 Apple accounts have been hacked into. These iPhone owners that are victims to this attack were those who have performed a jailbreak on their phones.

This could be "the largest known Apple account theft caused by malware," security company Palo Alto Networks reports, according to CNN Money. Palo Alto Networks was able to discover the hack with the help of Chinese tech group WeipTech.

The malware called KeyRaider targets iPhone owners who have jailbroken their phones. A jailbroken phone eliminates the restrictions that Apple puts into iPhones and allows owners to install restricted apps.

The malware KeyRaider is mostly found in Chinese websites and apps that provide software for jailbroken iPhones. The malware has spread to 18 countries, including the United States, and is no longer exclusive to China.

An infected iPhone with KeyRaider will be extremely vulnerable. The iPhone will give up its iTunes App store information, including the Apple ID user name and password and the iPhone's unique ID to the hackers. The owners' history of purchases in the App Store is also revealed, and owners will not be able to restore or recover their iPhones after they are infected.

The hackers are allowing other people to take advantage of the valuable hacked information. They are publishing advertisements that let people purchase iTunes apps from the hacked users' accounts. This means the hacked individuals are responsible for all of the purchases that strangers have made from their accounts.

Victims are seeing iTunes purchases for apps that they never purchased. They are also seeing their phones being locked, and the hackers are demanding money to unlock them.

Due to a hack like this one, Apple reminds users that jailbreaking their iPhones can make them vulnerable to attacks.

According to The Telegraph, users who have not jailbroken their iPhones are not affected by KeyRaider.
