Hackers show ways to protect your iPhone.

Hackers have stolen more than 225,000 Apple accounts from iPhone customers.

Security company Palo Alto Networks is calling the attack “the largest known Apple account theft caused by malware.” Palo Alto Networks (PANW) discovered the hack along with Chinese tech group WeipTech.

The good news for most iPhone customers is that the malware, nicknamed KeyRaider, only targets “jailbroken” iPhones.

Jail-breaking allows iPhone owners to access parts of a phone’s file systems that are otherwise restricted for security reasons.

KeyRaider is mostly found in Chinese websites and apps that provide software for jailbroken iPhones. But the malware has spread far beyond China, showing up in 18 countries, including the United States.

Once infected with the KeyRaider malware, a jailbroken iPhone will give up all of its owner’s iTunes App Store information to the hackers, including the Apple (AAPL, Tech30) account username, password and the iPhone’s unique ID.
