Pangu's jailbreak for Apple's iOS 8.4.1 was unveiled at the HackPwn 2015 Conference a week ago, but the team recently announced that they are not releasing the tool to the public.

The reason behind this is the imminent release of Apple's new operating system, the iOS 9, Christian Today reported. According to suggestions, users who want to jailbreak their iPhones should stay with the iOS 8.4 in the meantime instead of upgrading to iOS 8.4.1 using a jailbreaking tool.

Upon upgrading to the iOS 8.4.1, users can no longer go back to the earlier iOS 8.4 edition. The only option available to them is to wait for the release of an iOS 9 jailbreak, the news outlet explained.

KeyRaider Malware

An iOS 8 Cydia tweak reportedly left a vulnerability to more than 225,000 jailbroken Apple devices and left them exposed to a malware called the KeyRaider. Together with WeipTech, Cybersecurity company Palo Alto Networks found out this week that the devices infected with the malware are all jailbroken.

The breach reportedly stole Apple ID usernames, passwords, and device GUID from owners of the jailbroken devices. The malware works by "intercepting iTunes traffic on the device. KeyRaider steals Apple push notification service certificates and private keys, steals and shares App Store purchasing information, and disables local and remote unlocking functionalities on iPhones and iPads," Palo Alto Networks explained.

The malware originated from China and is only available in third-party Cydia repositories, the news outlet reported. The reason why this malware was downloaded by a lot of users is because it was hiding behind game cheats, system tune-ups, and features to get rid of advertisements in apps. These things are commonly downloaded by plenty of users.

Most users affected by the KeyRaider is in China, but the malware also reached iOS devices in France, Russia, Japan, United Kingdom, United States, Canada, Germany, Australia, Israel, Italy, Spain, Singapore, and South Korea, Palo Alto Networks listed. Some users reported that their stolen Apple accounts are displaying abnormal app purchasing history, while others said that their iOS devices are being held in ransom.

Despite longstanding warnings from Apple, numerous users still continue using various jailbreaking tools, which is said to make devices vulnerable and exposed to hackers. Apple's original security settings are no longer in effect once a device was jailbroken, CNET wrote. In addition, jailbreaking violates the tech giant's terms of service.

An Apple representative said that malwares and hackers are the reason why their devices come with security systems. "To protect our users from malware, we curate App Store content and ensure all apps in the App Store adhere to our developer guidelines," the rep added, as quoted by CNET.
