“This Connection Is Not Private” – What it Means and How to Protect Your Privacy

By McAfee

Have you ever been browsing online and clicked a link or search result that took you to a site that triggers a “your connection is not private” or “your connection is not secureerror code? If you’re not too interested in that particular result, you may simply move on to another result option. But if you’re tempted to visit the site anyway, you should be sure you understand what the warning means, what the risks are, and how to bypass the error if you need to.   

What does “this connection is not private” mean?

A “your connection is not private” error means that your browser cannot determine with certainty that a website has safe encryption protocols in place to protect your device and data. You can bump into this error on any device connected to the internet — computer, smartphone, or tablet.  

So, what exactly is going on when you see the “this connection is not private” error?  

For starters, it’s important to know that seeing the error is just a warning, and it does not mean any of your private information is compromised. A “your connection is not privateerror means the website you were trying to visit does not have an up-to-date SSL (secure sockets layer) security certificate. 

Website owners must maintain the licensing regularly to ensure the site encryption capabilities are up to date. If the website’s SSL certificate is outdated, it means the site owners have not kept their encryption licensing current, but it doesn’t necessarily mean they are up to no good. Even major websites like LinkedIn have had momentary lapses that would throw the error. LinkedIn mistakenly let their subdomain SSL certificates lapse.  

In late 2021, a significant provider of SSL certificates, Let’s Encrypt, went out of business. When their root domain officially lapsed, it created issues for many domain names and SSL certificates owned by legitimate companies. The privacy error created problems for unwitting businesses, as many of their website visitors were rightfully concerned about site security.  

While it does not always mean a website is unsafe to browse, it should not be ignored. A secure internet connection is critical to protecting yourself online. Many nefarious websites are dangerous to visit, and this SSL certificate error will protect you from walking into them unaware.   

SSL certification standards have helped make the web a safer place to transact. It helps ensure online activities like paying bills online, ordering products, connecting to online banking, or keeping your private email accounts safe and secure. Online security continues to improve with a new Transport Layer Security (TLS) standard, which promises to be the successor protocol to SSL. 

So be careful whenever visiting sites that trigger the “connection is not private” error, as those sites can potentially make your personal data less secure and make your devices vulnerable to viruses and malware 

Note: The “your connection is not private” error is Google Chrome‘s phrasing. Microsoft Edge or Mozilla Firefox users will instead see a “your connection is not secure” error as the warning message.   

How to fix the “connection is not private” error

If you feel confident that a website or page is safe, despite the warning from your web browser, there are a few things you can do to troubleshoot the error.  

  • Refresh the page. In some cases, the error is just a momentary glitch. Try reloading the page to rule out a temporary error.  
  • Close browser and reopen. Closing and reopening your web browser might also help clear a temporary glitch.  
  • If you’re on public WiFi, think twice. Hackers often exploit public WiFi because their routers are usually not as secure or well-maintained for security. Some public WiFi networks may not have an SSL connection, or they may limit your access to websites. You can safely browse more securely in public spaces if you have an antivirus software or virtual private network (VPN) solution. 
  • Use “Incognito” mode. The most used browsers (Google Chrome browser, Mac‘s Safari, Mozilla Firefox, and Microsoft Edge) offer an “Incognito mode” that lets you browse without data collecting in your history or cache. Open the site in a new incognito window and see if the error still appears.  
  • Clear the cache on your browser. While cookies make browsing the web more convenient and personalized, they also can hold on to sensitive information. Hackers will take advantage of cached data to try and get passwords, purchase information, and anything else they can exploit. Clear browsing data before going to a site with the “connection is not secure” error to help limit available data for hackers 
  • Check the computer’s date and time. If you frequently see the “connection is not private” error, you should check and ensure your computer has the accurate time and date. Your computer’s clock can sometimes have time and date stamp issues and get glitchy in multiple ways. If it’s incorrect, adjust the date and set the time to the correct settings.  
  • Check your antivirus software. If your antivirus software is sensitive, you may have to disable it momentarily to bypass the error. Antivirus software protects you, so you should be careful to remember to turn the software back on again after you’ve bypassed the error.  
  • Be sure your browsers and operating systems are up to date. You should always keep your critical software and the operating system fully updated. An outdated browser can start getting buggy and can increase the occurrence of this kind of error.  
  • Research the website. Do a quick search for the company of the website you wish to visit and make sure they are a legitimate business. You can search for reviews, Better Business Bureau ratings, or check for forums to see if others are having the same issue. Be sure you are spelling the website address correctly and that you have the correct URL for the site. Hackers can take advantage of misspellings or alternative URLs to try and snare users looking for trusted brands. 
  • If it’s not you, it’s them. If you’ve tried all the troubleshooting techniques above and you still see the error, the problem is likely coming from the site itself. If you’re willing to take your chances (after clearing your browser’s cache), you can click the option to “proceed to the domain,” though it is not recommended. You may have to choose “advanced settings” and click again to visit the site.   

Remember, you are taking your chances anytime you ignore an error. As we mentioned, you could leave yourself vulnerable to hackers after your passwords, personal information, and other risks.  

How to protect your privacy when browsing online

Your data and private information are valuable to hackers, so they will continue to find new ways to try and procure it. Here are some ways to protect yourself and your data when browsing online.  

  • Antivirus solutions are, hands down, your best line of protection against hacking. Solutions like McAfee+ Ultimate offer all the tools you need to secure your data and devices.  
  • Use strong passwords and two-factor authentication when available. 
  • Delete unused browser extensions (or phone apps) to reduce access. 
  • Always keep your operating system and browsers up-to-date. You can open system preferences and choose to update your system automatically. 
  • Use a secure VPN solution to shield your data when browsing. 
  • Use your favorite browser’s incognito mode to reduce the data connected to your devices. 
  • Remove any 3rd party apps from your social media accounts — especially if you’ve recently taken a Facebook quiz or similar (also, don’t take Facebook quizzes). 
  • Engage the highest privacy settings in each of your browsers. 
  • Always check the address bar for HTTPS before sharing credit cards or other sensitive data on a website. 
  • Share less personal and private information on social media.

How To Do A Virus Scan

By McAfee

Whether you think you might have a virus on your computer or devices, or just want to keep them running smoothly, it’s easy to do a virus scan. How to check for viruses depends on the software and device you have, so we’ll go through everything you need to know to run a scan effectively and keep your computers, phones and tablets in tip-top shape.

Do You Need a Virus Scan?

First, let’s cover a few of the telltale signs your device might have a virus. Is your computer or device acting sluggish or having a hard time booting up? Have you noticed missing files or a lack of storage space? Have you noticed emails or messages sent from your account that you did not write? Perhaps you’ve noticed changes to your browser homepage or settings? Or maybe, you’re seeing unexpected pop-up windows, or experiencing crashes and other program errors. These are all examples of signs that you may have a virus, but don’t get too worried yet, because many of these issues can be resolved with a virus scan.

What Does a Virus Scan Do?

Each antivirus program works a little differently, but in general the software will look for known malware that meets a specific set of characteristics. It may also look for variants of these known threats that have a similar code base. Some antivirus software even checks for suspicious behavior. If the software comes across a dangerous program or piece of code, it removes it. In some cases, a dangerous program can be replaced with a clean one from the manufacturer.

How to Check for Viruses

The process of checking for viruses depends on the device type and its operating system. Check out these tips to help you scan your computers, phones and tablets.

On a Windows computer

If you use Windows 10, go into “Settings” and look for the “Updates & Security” tab. From there you can locate a “Scan Now” button.

Of course, many people have invested in more robust antivirus software that has a high accuracy rate and causes less drain on their system resources, such as McAfee Total Protection. To learn how to run a virus scan using your particular antivirus software, search the software’s help menu or look online for instructions.

On a Mac computer

Mac computers don’t have a built-in antivirus program, so you will have to download security software to do a virus scan. There are some free antivirus applications available online, but we recommend investing in trusted software that can protect you from a variety of threats. Downloading free software and free online virus scans can be risky, since cybercriminals know that this is a good way to spread malware.

Whichever program you choose, follow their step-by-step instructions on how to perform a virus scan, either by searching under “help” or looking it up on their website.

On smartphones and tablets

Yes, you can get a virus on your phone or tablet, although they are less common than on computers. However, the wider category of mobile malware is on the rise and your device can get infected if you download a risky app, click on an attachment in a text message, visit a dangerous webpage, or connect to another device that has malware on it.

Fortunately, you can protect your devices with mobile security software. It doesn’t usually come installed, so you will have to download an application and follow the instructions.

Because the Android platform is an open operating system, there are a number of antivirus products for Android devices, that allows you to do a virus scan.

Apple devices are a little different because they have a closed operating system that doesn’t allow third parties to see their code. Although Apple has taken other security precautions to reduce malware risks, such as only allowing the installation of apps from Apple’s official app store, these measures aren’t the same as an antivirus program.

For more robust protection on your Apple devices, you can install mobile security software to protect the private data you have stored on your phone or tablet, such as contacts, photos and messages.

All-In-One Protection:

If safeguarding all your computers and devices individually sounds overwhelming, you can opt for a comprehensive security product that protects computers, smartphones and tablets from a central control center, making virus prevention a breeze.

Why are virus scans so important?

New online threats emerge every day, putting our personal information, money and devices at risk. In the first quarter of 2019 alone McAfee detected 504 new threats per minute, as cybercriminals employed new tactics. That’s why it is essential to stay ahead of these threats by using security software that is constantly monitoring and checking for new known threats, while safeguarding all of your sensitive information. Virus scans are an essential part of this process when it comes to identifying and removing dangerous code.

How often should you run a virus scan?

Most antivirus products are regularly scanning your computer or device in the background, so you will only need to start a manual scan if you notice something suspicious, like crashes or excessive pop-ups. You can also program regular scans on your schedule.

Preventing Viruses

Of course, the best protection is to avoid getting infected in the first place. Here are a few smart tips to sidestep viruses and other malware:

  • Learn how to surf safely so you can avoid risky websites, links and messages. This will go a long way in keeping you virus-free.
  • Never click on spammy emails or text messages. These include unsolicited advertisements and messages from people or companies you don’t know.
  • Keep the software on your computers and devices up to date. This way you are protected from known threats, such as viruses and other types of malware.
  • Invest in comprehensive security software that can protect all of your devices, such as McAfee LiveSafe.
  • Stay informed on the latest threats, so you know what to look out for. The more you know about the latest scams, the easier they will be to spot and avoid.

Can Apple Macs get Viruses?

By McAfee

It’s a long-standing question. Can Apple Macs get viruses?

While Apple does go to great lengths to keep all its devices safe, this doesn’t mean your Mac is immune to all computer viruses. So what does Apple provide in terms of antivirus protection? Let’s take a look along with some signs that your Mac may be hacked and how you can protect yourself from further threats beyond viruses, like identity theft.

Signs that your Mac may be hacked

Whether hackers physically sneak it onto your device or by tricking you into installing it via a phony app, a sketchy website, or a phishing attack, viruses and malware can create problems for you in a few ways:

  • Keylogging: In the hands of a hacker, keylogging works like a stalker by snooping information as you type.
  • Trojans: Trojans are type of malware that can be disguised in your computer to extract important data, such as credit card account details or personal information.
  • Cryptominers: Similar to trojans, this software hides on a device. From there, it harnesses the device’s computing power to “mine” cryptocurrencies. While cryptomining is not illegal, “cryptojacking” a device without the owner’s consent is most certainly illegal.

Some possible signs of hacking software on your Mac include:

Performance issues

Is your device operating more slowly, are web pages and apps harder to load, or does your battery never seem to keep a charge? These are all signs that you could have malware running in the background, zapping your device’s resources.

Your computer feels like it’s running hot

Like the performance issues above, malware or mining apps running in the background can burn extra computing power (and data). Aside from sapping performance, malware and mining apps can cause your computer to run hot or even overheat.

Mystery apps or data

If you find apps you haven’t downloaded, along with messages and emails that you didn’t send, that’s a red flag. A hacker may have hijacked your computer to send messages or to spread malware to your contacts. Similarly, if you see spikes in your data usage, that could be a sign of a hack as well.

Pop-ups or changes to your screen

Malware can also be behind spammy pop-ups, changes to your home screen, or bookmarks to suspicious websites. In fact, if you see any configuration changes you didn’t personally make, this is another big clue that your computer may have been hacked.

What kind of antivirus do Macs have?

Macs contain several built-in features that help protect them from viruses:

  • XProtect and Automatic Quarantine: XProtect is Apple’s proprietary antivirus software that’s been included on all Macs since 2009. Functionally, it works the same as any other antivirus, where it scans files and apps for malware by referencing a database of known threats that Apple maintains and updates regularly. From there, suspicious files are quarantined by limiting their access to the Mac’s operating system and other key functions. However, .
  • Malware Removal Tool: To further keep Apple users protected, the Malware Removal Tool (MRT) scans Macs to spot and catch any malware that may have slipped past XProtect. Similar to XProtect, it relies on a set of constantly updated definitions that help identify potential malware. According to Apple, MRT removes malware upon receiving updated information, and it continues to check for infections on restart and login.
  • Notarization, Gatekeeper, and the App Review Process: Another way Apple keeps its users safe across MacOS and iOS devices is its Notarization Apps built to run on Apple devices go through an initial review before they can be distributed and sold outside of Apple’s App Store. When this review turns up no instances of malware, Apple issues a Notarization ticket. That ticket is recognized in another part of the MacOS, Gatekeeper, which verifies the ticket and allows the app to launch. Additionally, if a previously approved app is later to found to be malicious, Apple can revoke its Notarization and prevent it from running.

Similarly, all apps that wish to be sold on the Apple App Store must go through Apple’s App Review. While not strictly a review for malware, security matters are considered in the process. Per Apple, “We review all apps and app updates submitted to the App Store in an effort to determine whether they are reliable, perform as expected, respect user privacy, and are free of objectionable content.”

Do I need to purchase antivirus for my Mac?

There are a couple reasons why Mac users may want to consider additional protection in addition to the antivirus protection that Mac provides out of the box:

  1. Apple’s antivirus may not recognize the latest threats. A component of strong antivirus protection is a current and comprehensive database of virus definitions. As noted above, , leaving Mac owners who solely rely on XProtect and other features susceptible to attack.
  2. Apple’s built-in security measures for Macs largely focus on viruses and malware alone. While protecting yourself from viruses and malware is of utmost importance (and always will be), the reality is that antivirus is not enough. Enjoying the life online today means knowing your privacy and identity are protected as well.

In all, Macs are like any other connected device. They’re susceptible to threats and vulnerabilities as well. Looking more broadly, there’s the wider world of threats on the internet, such as phishing attacks, malicious links and downloads, prying eyes on public Wi-Fi, data breaches, identity theft, and so on. It’s for this reason Mac users may think about bolstering their defenses further with online protection software.

 Further protecting your Mac from viruses and attacks

Staying safer online follows a simple recipe:

  • Being aware of the threats that are out there.
  • Understanding where your gaps in protection are.
  • Taking steps to protecting yourself from those threats and closing any gaps as they arise.

Reading between the lines, that recipe can take a bit of work. However, comprehensive online protection can take care of it for you. In particular, McAfee Total Protection includes an exclusive Protection Score, which checks to see how safe you are online, identifies gaps, and then offers personalized guidance, and helping you know exactly how safe you are.

An important part of this score is privacy and security, which is backed by a VPN that turns on automatically when you’re on an unsecure network and personal information monitoring to help protect you from identity theft—good examples that illustrate how staying safe online requires more than just antivirus.

Consider your security options for your Mac

So, Macs can get viruses and are subject to threats just like any other computer. While Macs have strong protections built into them, they may not offer the full breadth of protection you want, particularly in terms of online identity theft and the ability to protect you from the latest malware threats. Consider the threats you want to keep clear of and then take a look at your options that’ll help keep you safe.

Apple Users: This macOS Malware Could Be Spying on You

By Vishnu Varadaraj

In 2018, Macs accounted for 10% of all active personal computers. Since then, popularity has skyrocketed. In the first quarter of 2021, Macs experienced 115% growth when compared to Q1 2020, putting Apple in fourth place in the global PC market share. It is safe to say that Macs are well-loved and trusted devices by a significant portion of the population — but just how safe are they from a security perspective? 

Many users have historically believed that Macs are untouchable by hackers, giving Apple devices a reputation for being more “secure” than other PCs. However, recent attacks show that this is not the case. According to TechCrunch, a new malware called XCSSET was recently found exploiting a vulnerability that allowed it to access parts of macOS, including the microphone, webcam, and screen recorder — all without consent from the user.  

Let’s dive deeper into how XCSSET works.  

Manipulating Macs with Zero-Day Exploits 

Researchers first discovered XCSSET in 2020. The malware targeted Apple developers and the projects they use to build and code apps. By targeting app development projects, hackers infiltrated apps early in their production, causing developers to unknowingly distribute the malware to their users.  

Once the malware is running on a user’s device, it uses multiple zero-day attacks to alter the machine and spy on the user. These attacks allow the hacker to:   

  • Steal cookies from the Safari browser to gain access to a user’s online accounts. 
  • Quietly install a development version of Safari that allows attackers to modify and snoop on virtually any website. 
  • Secretly take screenshots of the victim’s device.  

XCSSET’s Significance for macOS Users 

While macOS is supposed to ask users for permission before allowing any app to record the screen, access the microphone or webcam, or open the user’s storage, XCSSET can bypass all of these permissions. This allows the malware to sneak in under the radar and inject malicious code into legitimate apps that commonly ask for screen-sharing permissions such as Zoom, WhatsApp, and Slack. By disguising itself among these legitimate apps, XCSSET inherits their permissions across the computer and avoids getting flagged by macOS’s built-in security defenses. As a result, the bug could allow hackers to access the victim’s microphone, webcam, or capture their keystrokes for login credentials or credit card information.  

How to Stay Protected Against macOS Malware 

It is unclear how many devices were affected by XCSSET. Regardless, it is crucial for consumers to understand that Mac’s historical security reputation does not replace the need for users to take online safety precautions. The following tips can help macOS users protect themselves from malware:  

1. Update your software.   

Software developers are continuously working to identify and address security issues. Frequently updating your devices’ operating systems, browsers, and apps is the easiest way to have the latest fixes and security protections. For example, Apple confirmed that it addressed the bug exploited by XCSSET in macOS 11.4, which was made available on May 24th, 2021. 

2. Avoid suspicious emails or text messages from unknown senders.  

Hackers often use phishing emails or text messages as a means to distribute malware by disguising their malicious code in links and attachments. Do not open suspicious or irrelevant messages, as this can result in malware infection. If the message claims to be from a business or someone you know, reach out to the source directly instead of responding to the message. This will allow you to confirm the sender’s legitimacy.  

3. Use a comprehensive security solution. 

Use a solution like McAfee Total Protection, which can help protect devices against malware, phishing attacks, and other threats. It also includes McAfee WebAdvisor — a tool to help identify malicious websites. 

Regardless of whether you are Team PC or Team Mac, it is important to realize that both platforms are susceptible to cyberthreats that are constantly changing. Doing your research on prevalent threats and software bugs puts you in a better position to protect your online safety.
