An iOS bug is preventing VPN apps from encrypting all traffic

Here’s what you need to know right now

Ghosties using iPhones and iPads, we have some not-so-great news for you.

There’s an unpatched iOS bug out there, blocking VPN apps from encrypting all your internet traffic.

The bug was first discovered in iOS version 13.3.1, but it made it to the latest iOS version, 13.4.

It’s been rated with a 5.3 CVSS v3.1 base score. It’s a Medium.

As of now, Apple hasn’t disclosed any plans for a patch.

Are you safe? Encrypt your online data with CyberGhost VPN and make sure nobody can spy on your online activity. Use CyberGhost anytime, anywhere, on both iOS and macOS.

What’s going on

Every time you establish a connection to a VPN server on an iOS device, all your previously existing internet connections and apps are supposed to be terminated and restarted.

The process ensures that everything then connects through the VPN’s encrypted tunnel. It’s essentially how a VPN works.

With VPN software, you can hide your IP address and enforce the VPN’s IP address through all apps.

However, this iOS bug causes some internet connections to continue using your original IP address. You’re left with privacy and security concerns, vulnerable to network snooping.

What we know about the bug

The bug was first reported by Proton VPN, who dubbed it the “VPN bypass bug.”

According to them, the bug’s behavior is quite erratic. Some connections re-establish through the VPN tunnel after a short while, others take anywhere from minutes to hours.

For example, Apple’s push notification service seems to maintain a long connection between the device and Apple’s servers.

It’s still not clear how this bug affects messaging, banking, or social media apps, which generally contain more sensitive personal information.

What you can do right now

There is no reliable workaround for the bug yet.

But there are some things you should keep in mind:

      • Internet connections established after you connect to VPN are not affected.
      • There’s no guarantee that connections established before opening a VPN will close and restart. There’s also no estimate on how long these will remain unencrypted.
      • It’s best to force shut down all apps before connecting to a VPN, to prevent having your IP address exposed.
      • A VPN app, like CyberGhost VPN, can only access your network settings to encrypt your internet traffic. It should not have permission to access other apps or change connection settings in third-party apps.

If you’re using CyberGhost VPN on an iOS device (iPhone or iPad), make sure to follow these recommendations.

However, if you’re a Ghostie using any other device, everything’s okay for you.

We’ll keep updating this article as the story develops.

Until next time, stay safe and secure!

When will this issue of shuting down the wifi connection after the screen of the iphone goes off, is going to be fixed??
It’s been happening since I subscribed about 6 months ago, and is still happening now with the ios14.

Hi, Andrei! The issue you’re describing doesn’t seem to be related to the bug mentioned in the article, but rather to your device’s power options. To conserve battery, most phones will shut down internet connection, when your device is in standby mode. Check the settings and disable this option to enjoy full VPN protection.

Did iOS 14 fix the vpn bug?

Hi, Kenny! The bug is fixed on iOS 14. 🙂

Are there better servers than others to use regarding speed, reliability, etc? Better countries?

Hiya, Priva! We’re always investing in and upgrading our server network to ensure you get the best performance. However, some factors like your location and network settings can influence your VPN connection. You can check out the Find the best VPN server option to see which one is best suited for you.

Please inform us in the iOS App when this is fixed, not only on the website.

Hi, Fuzaili! Glad you enjoyed. 😊

What’s the latest news to solve the problem with Apple ? As we are paying for none encrypted communication.

Hi, Ghostie! Unfortunately, Apple’s release notes for iOS version 13.5 do not mention anything related to this iOS bug. We’re still awaiting further developments.

Thank you CG!! You have no idea how many smart phones you have saved from my short tempered hands. Especially when one is not so tech savvy!!

Aww, thanks, Tony! We’re happy to hear our user-friendly app is keeping your devices safe. 😊

Hi there,

I’m using it from Spain and I might say I’m amazed!
I just tried the RO server and it has mazing speed on my iphone. Over 300mb down and 100+ mb for upload.
I can’t complain about my laptop either.
I can now watch amazon prime series from US with great speed. The quality of the video streamed is not extraordinary but it’s good. Like hd to fullhd good. And speedtest is amazing. With 181ms ping I reached 300mb with 11mb of upload. In a great measure it’s also thanks to the 600mb fiber provided by orange

Glad to hear everything is fine with the workaround, Ameri!

I t is great

Hi I’ve had this VPN for a week desperate to get some Real Privacy online yet still don’t feel that this VPN is not infiltrated on my iOS 13.4 device . If by applying your method of avoiding this bug is to really work should I not instantly change this VPNs password security?

Reply

Hi, Ghostie! The bug prevents all apps from being redirected through the VPN tunnel once a connection to one of our VPN servers has been established. Make sure to force close all apps before connecting through our app, since internet connections established after you connect to VPN are not affected. Your credentials are not affected in any way.

So, for a recent client, will the 45 days for refund, be extended if not satisfied !
Because obviously, it seems like no one knows at which degrees this VPN is actually working at it’s best. As for us as a customer of this product it’s even more difficult to know ! Specially, i am a user of both iPhone 8 and the latest mini iPad.
So tell me, should I opt out and wait till this fix to be a Ghostie again, or should You let your customers have a longer period than 45 days to be reimbursed if needed ?
Keep up the good works !
Awaiting to have some news !
Be safe, Stay safe and Smile 😉

Go figure, Apple is at it again, do you think it has anything to do with being made in China ? I’m going back to Android.

Reply

The hardware is not designed in China and the software never was… and what relevance is that anyway?

I canceled my subscription, because I do not know why the application ask for my passwords on all three devices please explain. When I didn’t put my password in it canceled me out, when I put it in then it let me in.

Hi, Frank! If you’re referring to our app, you need to login with your username and password, in order to use all our Premium features.

I think what you meant is that even though TECHNICALLY SPEAKING China has not designed the hardware or the software for iOS, China has no “misgivings” to bootlegging or pirating or sabotaging anything & everything “out there” if in doing so it will serve to be in China’s best interests. Foreign Patent Laws & “Rules of Conduct” have no bearing to the Chinese Government if by obeying those laws it would cause the loss of anything that would be beneficial to China. In basic words…. you don’t have ANY trust in the Chinese.

Would toggling in and out of airplane mode not force my connection to re-establish VPN?

Reply

Hi, Jeffrey! Under normal circumstances, airplane mode would work to re-establish the VPN connection. But with this bug, it’s not very clear if the apps that were not routered through the VPN would be switched. For the tie being, it’s best to manually close all apps before airplane mode.

Good information thanks.
I have a question
I Been using a server in Argentina, and for the pass week is not available anymore
Any idea if it will be available soon?
Otherwise I will have to start looking for other VPN.

Reply

Hi, Ben! The Argentina servers are down for a short while due to maintenance, but they’ll be back up soon.

Hi! Unfortunately, there are no definite plans in place to translate the articles into other languages at the moment. For the time being, you can make use of an online translator, like Google Translate.

Apple does not think it is a bug. It is a feature for those who do not appreciate us using VPNs.

Force close? Excuse my ignorance. Is that just individually closing every app or something more? I am using an iPad. TIA

Reply

Hi, Sarah! From your Home screen, swipe up from the bottom of the screen to see your recently used apps. From there you can swipe to force them to shut down.

This is great

I find it strange that you let me start a subscripction yesterday If you knew this friday?
And also it would have been nice If you told me about this in my e- mail conversations regarding a refund as it didn’t work for me.
What do I have to do to keep my phone / safe at this stage?

Hi, Lina! Our subscriptions can be used on various different operating systems, not just iOS devices. We expect Apple will fix the bug in a timely manner. In the meantime, make sure to force close all apps before connecting to a VPN server.

Thanks guys keep up te good work

Fake article you don’t need vpn on Apple devices.

Reply

Hi, Robert! While some might regard Apple devices as more secure, they don’t natively encrypt internet traffic. A VPN works by hiding your IP address and encrypting your entire internet traffic, offering online anonymity and privacy. It’s a great way to keep your connections away from prying eyes and your data safe.

Why is it that I am informed of that once the payment is made I should have been informed before
Don t like that at all
