Basically, even though you were using a VPN while running an app like iCloud or Siri, a lot of data would leak out of the VPN tunnel. That means Apple would see your IP address and what country you’re using their apps from.
Not to mention hackers would just need to find a vulnerability in one of Apple’s apps, and they’d be able to take over your device since they’d bypass your firewall. Or they could take advantage of the fact that your VPN is leaking data, and spy on your traffic to steal sensitive information.
Want to learn exactly what happened? We’ll tell you all you need to know in this article.
What Exactly Caused That Issue?
Apparently the Big Sur update came with a special key called “ContentFilterExclusionList.” That key is a part of the NetworkExtension API which a lot of security tools like VPNs and firewalls now use.
Essentially, here’s how the ContentFilterExclusionList key affects firewalls and VPNs:
It lets Apple’s apps bypass the encrypted VPN tunnel.
It allows Apple’s apps to communicate with the Internet even if the firewall says they can’t.
Did the Big Sur Update Affect All VPNs?
Time for some good news – this update doesn’t impact all VPN services! It only affects VPNs that use the NetworkExtension API. Luckily, it’s not mandatory for them to do so. As a result, many VPN providers avoided it, and used different methods (utun devices or PFCTL, just to name a few examples).
Those services are not susceptible to Big Sur’s forced traffic leaks. You can safely use Mac apps with them without having to worry about your data being compromised. Also, it looks like Apple’s built-in VPN wasn’t susceptible to traffic leaks either.
If you need help finding the best VPNs for Mac computers, just follow that link. It’s a guide from ProPrivacy (a leading VPN review site) that showcases VPNs that work extremely well on Mac devices. ProPrivacy even interviewed most of the providers on that list to confirm that their services can’t be compromised by Big Sur.
Did Apple Fix the Big Sur Issue?
Yes – Apple got rid of this problem when they launched the Big Sur 11.2 update. To make Mac apps fully compatible with firewalls and VPNs, Apple simply deactivated the ContentFilterExclusionList key.
Besides that security issue, Apple also fixed numerous other bugs – like System Preferences not unblocking when you enter your admin password, or iCloud Drive turning off because you disabled the iCloud Drive Desktop & Documents Folders option.
Apple also fixed other security flaws – like a user being able to rejoin an iMessage group even though they were removed from it. To read about all the improvements, check out this support article from Apple.
To update to Big Sur 11.2, just do this:
In the upper-left corner of macOS Big Sur, click the Apple logo.
Select System Preferences.
Next, pick Software Update.
Click Install Now.
Now just wait for the update to finish downloading and installing. Depending on your speeds, it could take a bit since it’s around 3.66GB.
While Big Sur brought a lot of improvements, it also endangered user data by allowing Mac apps to bypass firewalls and VPNs. Luckily, not all VPN clients were affected, and Apple solved this problem with the Big Sur 11.2 update (so be sure to download and install it ASAP).

Reasons to Protect Your Business with White Hackers
Hacking is the process associated with spyware programs to gain unauthorized access to a business system. With malicious actions, a hacker can steal confidential information, download business files, etc. From the point of view of unauthorized access, such actions are illegal. The opposite person to a black hacker is an ethical hacker. Such a specialist legitimately sneaks into your business system to check for vulnerabilities. Login is only done with the permission of the business manager. Therefore, hire a hacker for business is the right decision.
Is there a demand for ethical hackers?
Let’s see what do ethical hackers do. White or ethical hackers provide services to increase information systems’ security with the knowledge and agreement with the customer within the framework of a contractual relationship or according to the program of reward for vulnerabilities found. Are you complicated to understand? Let’s make it simpler: white hackers hack you and your resources with your permission and for money and show how they did it so that you fix this bug and no one else hacks you.
White hackers will offer you penetration testing, or red teaming, ranging from $ 3,000 to millions of dollars, depending on the task’s complexity. The range of their services and prices varies significantly across the market and depends on specialists’ competence and company size. As you can see, the service fees are high, but darker if there were no demand, the price would not have risen so much.
What companies hire ethical hackers?
The American platform Bugcrowd has calculated that ethical hackers who help companies find bugs and holes in security systems make up to $ 500,000 a year. Virtually every major tech company and financial institution is working with ethical hackers, including Tesla, Amazon, and Facebook. Large companies are willing to pay large sums of money to hire burglars. Tesla and IJet pay hackers between $ 1,000 and $ 15,000 for finding a bug or loophole in the system, depending on its complexity and the severity problem. Mastercard is ready to pay ethical hackers from $ 3 thousand. This practice of finding errors for a fee is called bug bounty in the professional community. In American companies, there is a fairly common practice of creating separate bug bounty programs when any user can report security holes.
Do ethical hackers need a degree?
Ethical hackers usually work to find critical vulnerabilities with a price of $ 3-5 thousand. As a rule, such specialists have certificates of Certified Ethical Hacker, Offensive Security Certified Professional, and others. Accordingly, to master the direction of hacking, it is not necessary to have a scientific degree. It is enough to pass certified courses by good experts.
Ethical Hacking – Reasons to Use the Service
White hackers are known to partner with many companies that report their cybersecurity. A common task for a white hacker is to conduct penetration tests on a business system. White hackers conduct authorized hacking of the client’s systems and products while testing them for vulnerabilities and resistance to attacks. This is just a test, not to steal personal data. The system is hacked under the direction of the company. The expert records all the results and draws up a detailed report, which indicates where the vulnerabilities are in the system. Do you think about the service of white hackers? Do you want to hire a specialist, but you are not sure if? Then below, we have described important reasons.
An ethical hacker can skillfully handle a VPN
Regular networks of proxy servers can no longer guarantee complete anonymity and security. Virtual private networks have long replaced proxies. VPN provides isolated access to the network through VPN server chains and encryption of transmitted data. Therefore, if you want to hide your activity from the provider and third parties, you need to use VPN. But not all VPNs can keep you from hacking.
Only ethical hackers know how to handle the program and select the VPN servers list properly. The best service is VeePN. All you have to do is register on the VeePN website, then download the app to start using the VPN right away without the need to configure anything. You can connect to many countries because the developers took care of their users and created a huge selection of VPN server locations. You can enjoy an extensive network of VPN servers in 50 locations across 42 countries. VeePN is available on laptops, computers, and mobile devices. One account can use the service on several different devices. The program also offers a trial so that every user can be convinced of the quality of services.
Injection of malicious code
These vulnerabilities allow writing to the database of a site, service, or application. What is the threat? For example, if a hacker found such a vulnerability on the website, he could easily:
change any news and sections on the site, adding or deleting part of the data;
add or remove administrators, editors, moderators;
place your ad, links, text, code, script;
sell links from someone else’s site.
To avoid this, you must partner with ethical hackers.
Invalid authentication and session management
A fairly common vulnerability, as a rule, is caused by insufficient thoughtfulness of the authorization logic or additional session checks. From interesting examples of exploitation, we immediately remembered one exchange. Due to incorrect management of sessions combined with an IDOR vulnerability, it was possible to reset the password from any account by changing the email for recovery. Therefore, to avoid this threat, you need the services of an ethical hacker.
The specificity of such attacks is that malicious code can use user authorization in the web system to gain extended access to it or to obtain user authorization data. Hackers can insert malicious code into a page either through a vulnerability in the web server or through a vulnerability on the user’s computer. The idea here is to force the attacked site to transmit data to the attacker’s site. Don’t want to get under attack – you need white hackers.
Ethical hackers are always proactive
If you use the services of a white hacker, then he will not wait until the cybersecurity of your business is violated, or a data leak occurs. The white hacker is immediately aware of the existing vulnerabilities before something threatens the security of the business. That is, an expert will prevent a cyber-attack.
Ethical hackers are cost-effective
Black hackers can do a lot of damage to a business, resulting in bailouts or significant money losses. If an ethical hacker can detect the weakest points in the business system and prevent an attack, you will save much more money, even though an ethical hacker’s services are high.
Ethical hackers know everything about black hackers
Even if you know how black hackers operate, you may not always stop his evil actions. Black hackers use many harmful programs that the average person does not know about in their work. In fact, by harming your business, they will earn money, although this is not legal. Ethical hackers, who know many programs and understand their functioning, will accordingly prevent any threat. You will be free from problems, and your business will flourish.
