The latest version of iOS is now available to all iOS users ( from iPhone 5s and up). This latest release brings up bug fixes and at least one new feature for cybersecurity-addicted users. This new feature is named “USB Restricted Mode,” and it is located in Settings of your iPhone under “Touch ID & Passcode” menu.
Apple’s description of this new feature:
“If you don’t first unlock your password-protected iOS device – or you haven’t unlocked and connected it to a USB accessory within the past hour – your iOS device won’t communicate with the accessory or computer, and in some cases, it might not charge. You might also see an alert asking you to unlock your device to use accessories.”
Simply said: the default setting for this feature is to not allow USB accessories to work with the iPhone or iPad when locked for more than an hour. Meaning that when you plug a USB accessory into your iDevice, that item won’t work unless the Apple’s device is unlocked first and the user answers a prompt on their device to recognize the new USB accessory; if the user agrees with the prompt, that USB device will be able to work with the device without any issue. This new feature is very useful for users because it protects their device against hackers or anyone else who might want to access a locked iPhone with hacking tools like GrayKey.
Companies and individual people must take certain precautions against this growing phenomenon of legal or illegal cyber attacks like GrayKey; for that they should implement at least a cybersecurity solution, like an antivirus, to protect their systems. Necessary things like regularly updating operating systems, using antivirus for Windows
or antivirus for Mac
depending on which OS your device is using. Companies must also hire professional cybersecurity firms to do regular checkups to their internal network a couple of times per year. These checkups must always include a penetration test and various ethical hacking test.
This is good news from Apple because by enabling this feature that requires a user to unlock the phone to use any USB accessories again, Apple seems to be making a new attempt to keep both hackers and government agencies out of their users’ iPhones.
If we look at the bugs list, we find that one of the flaws fixed in this update is an after-effect of Chinese government censorship. This government censorship works like this: In some versions of iPhones with specific region settings in place, just typing the word “Taiwan” or using the Taiwan flag emoji would cause the phone to completely crash. This bug is identified by the vulnerability code CVE-2018-4290 and its patch is done not to remove the censorship, but to fix the flaw in the code that was causing it to crash phones in certain configurations.
The full details of the security updates for iOS 11.4.1 can be found in Apple’s article about the security content of iOS 11.4.1. Apple has released iOS 11.4.1 on 9 July, so if you have an iPhone 5s or iPad Air or newer, you’ll find the update via “Software Updates” in the Settings app.
Keep in mind that every device has a significant value that must be protected by at least cybersecurity solution like an antivirus. Depending on which OS your device is running, install an antivirus for Windows or antivirus for Mac for total protection. Companies must take an extra step and hire a professional cybersecurity firm that will run various cybersecurity tests on your company’s network to implement only the best possible cybersecurity solution. Always opt for a package that includes at least a penetration test and ethical hacking test. For companies that exist 100% online, we recommend the using of cyber-secured web hosting services.
