What’s the Meaning of VPN? VPN Defined

Read Time:6 Minute, 17 Second

A virtual private network (VPN) is a tool that enables users to protect their privacy while using an internet connection. VPNs create an encrypted tunnel — a private link between your device and the VPN server 

Essentially, this private link or tunnel keeps external influences out and allows your data to travel in an encrypted manner, enhancing security. The network’s privacy also makes sure your Internet Protocol (IP) address and browsing history is hidden online.  

[Text Wrapping Break]VPNs use several VPN protocols like OpenVPN, IPSec/IKEv2, PPTP, SSTP, and WireGuard to protect you. In particular, McAfee® Safe Connect VPN supports the OpenVPN protocol, which is an open-source and highly secure protocol running on TCP or UDP internet protocol and used by many VPN providers globally. [Text Wrapping Break][Text Wrapping Break]Read on to know more about how VPNs work and learn to install one. 

What does a VPN do?

The best way to stay secure online is to minimize your digital footprint. A good VPN service allows you to do exactly this, acting as an additional layer of protection for your online activities 

The primary function of a VPN is encryption. Most websites and online browsers already have some form of encryption. For example, when you purchase something on Amazon, you have to enter your credit card details and address. Encryption creates a private tunnel for data transmission between your device and Amazon to make sure no one else can watch what you’re doing.  

A VPN app does the same thing with an added level of security. The data that you pass to a VPN server is anonymized before it goes to the internet. In short, your device establishes an encrypted connection with the VPN server instead of connecting directly through the internet. So, the encryption protects your data and digital footprint from anyone outside the “private tunnel” between you and the secure VPN server 

Additionally, VPNs allow you to change or hide your IP address. An IP address is a number linked to a particular computer and network. Changing your IP address can trick the servers into thinking you’re connecting from a different geographical location. This can help improve security and provide additional benefits discussed below. 

You can also use a VPN to hide your IP address. This may be helpful if you’re trying to access content from other countries (for example, Netflix may have different content in different countries) or trying to keep your internet search history away from the prying eyes of a third-party like your internet service provider or a government. 

Using a VPN can help improve your online security. Nearly every internet activity — website and social media browsing, paying bills, online shopping, data sharing, and more — can be tracked by others. [Text Wrapping Break][Text Wrapping Break]Read on to learn about who typically uses a VPN and understand whether you should consider installing one. 

Who typically uses VPNs?

Given the extra security that VPN connections provide, you can gain something from using a VPN client. So, if you’re an individual concerned about your online privacy or just want to browse online anonymously — consider using a VPN. A VPN enables you to use the internet without third parties seeing your identity or identifying you via your search history since they don’t know what you were searching about or using the internet for. 

Big tech has had a long history of tracking private data for their gains. These companies regularly bundle data into coherent profiles and sell it to third parties. Additionally, they use private data to demonstrate targeted advertisements or manipulative content that makes you more likely to purchase their products. [Text Wrapping Break][Text Wrapping Break]So, it’s worthwhile to use a VPN if you regularly shop online or bank online. A VPN gives you that additional protection that can help prevent hackers or malicious third parties from accessing your information.[Text Wrapping Break][Text Wrapping Break]VPNs are excellent mechanisms for you to protect your privacy online. And you should consider your personal context and conduct thorough research to find the best VPN for your needs. 

VPNs are particularly helpful if you travel a lot, either for business or for leisure. While traveling, it’s inevitable that you connect to random or unknown Wifi networks and it may be the case that these networks are spying on you. However, if you’re using a VPN to browse the web, these WiFi networks can’t track you or your search history. This ensures you maintain anonymity and are safe while using the internet.  

Should you use a VPN on your personal computer?

Yes, an additional layer of protection to your online activities is always good practice. A VPN allows individuals using a personal computer to stay vigilant, protect their data, and maintain anonymity while allowing them to still enjoy their online experience.  

Benefits of VPNs for personal use

VPNs provide more benefits than just serving as an additional layer for cybercriminals to pass through.  

Data privacy: The biggest reason to use a VPN is data privacy. Internet service providers (ISPs) regularly collect customer data and sell it to advertisers for money. Using a VPN allows you to hide your location and prevents your data from falling into the wrong hands. VPNs allow you to browse the internet in peace, knowing that no third parties are aware of your identity or can trace particular internet activity back to you.  
Security on public networks: Internet access through public Wi-Fi hotspots may not be the safest. User data on public networks is unprotected, making it vulnerable to bad actors who can use software to get past firewalls. With VPN encryption, you can remain safe even while using public Wi-Fi network connections 

Secure online transactions: Think about the number of times you log into your bank account or give out credit card information on e-commerce sites. You can never be too safe when it comes to financial information.  
Change your location: Some content is geo-blocked for various reasons. It could be streaming services like Netflix limiting access to their services or different countries censoring content. VPNs can hide your IP address to trick servers into believing that your location is different from where your router is physically. This can give you access to a lot more content.  

Can you set up a VPN yourself?

Depending on the VPN you’re using, it can be a straightforward process to connect a VPN to your Mac, Windows, iPhone, or Android mobile device. McAfee’s VPN works with multiple platforms and operating systems, including Microsoft Windows, macOS, Android, and iOS 

Use this guide to quickly set up a VPN with your device in a few simple steps.  

Secure your browsing with a VPN from McAfee

With McAfee +, you can minimize your digital footprint through a secure connection channel without compromising your browsing experience. Connect to public networks, make financial transactions online, and keep your personal data safe with McAfee.  

With our bank-grade AES-256 bit encryption technology and automatic protection, McAfee VPN protection can help safeguard all your online activities — allowing you to enjoy the internet the way it was meant to be enjoyed.

A Guide to Remove Malware From Your iPhone

Read Time:6 Minute, 1 Second

Malicious software, or “malware,” refers to any program designed to infect and disrupt computer systems and networks. The risks associated with a malware infection can range from poor device performance to stolen data. 

However, thanks to their closed ecosystem, built-in security features, and strict policies on third-party apps, Apple devices tend to be less prone to malware infections compared to their Android counterparts. But it’s important to note that they’re not completely without vulnerabilities 

Several iPhone viruses could infect your smartphone and affect its functionality, especially if you jailbreak your iPhone (that is, opening your iOS to wider features, apps, and themes).  

This article covers how you can detect malware infections and how to remove viruses from your device so you can get back to enjoying the digital world. 

How does malware affect iPhones?

Malware can affect your iPhone in a variety of ways. Here are a few telltale signs that your iPhone might have an unwelcome visitor.  

Your iPhone’s battery life is shorter than usual. 
Pop-up ads frequently appear. 
Apps crash for no apparent reason. 
Unfamiliar apps are installed on your iPhone. 
You notice high data usage. 
The operating system is noticeably slow. 
Your iPhone is overheating. 

How to check your iPhone for malware

If you notice any of the signs above, it’s a good idea to check for malware. Here are some steps you can take. 

Look for unfamiliar apps. If you’re anything like the average smartphone user, you’ve probably downloaded dozens (if not hundreds) of apps. The sheer number of programs on your iPhone makes it easy for malicious apps to hide in plain sight and remain undetected for a long time. Take some time to swipe through all of your apps and closely inspect any that you don’t remember downloading or installing. 
Check your data usage. Heavy data usage can be a sign of a malware infection, which is why you should keep an eye on it if you suspect a virus is in your system. To do so, go to Settings > Mobile Data and check if your data usage is higher than usual. 
Check power consumption. Some types of malware run in the background and consume a significant amount of power without you noticing. To make sure that no such apps are installed on your phone, head over to Settings > Battery and select a period of your choice. Uninstall any unfamiliar apps that stand out. 
Keep an eye on pop-up ads. Running into pop-up ads is inevitable when browsing the internet. However, your phone might be infected with adware if you’re getting them at an alarming frequency. 
Scan your phone using antivirus software. As helpful as these steps are, running a complete scan using antivirus software is one of the most effective ways to detect malware. If you don’t have one installed already, consider using McAfee Mobile Security. This comprehensive security solution provides full-scale protection that includes a safe browsing feature to protect your digital life, Wi-Fi privacy, and a VPN for a more secure internet connection. Highly effective scans detect malicious apps and unwanted visitors before they enter your digital space. 

How to remove malware from your iPhone

If you’ve confirmed malware on your iPhone, don’t worry. There’s still time to protect yourself and your data. Below is an action plan you can follow to remove malware from your device. 

Update your iOS (if applicable)

In many cases, hackers exploit outdated versions of iOS to launch malware attacks. If you don’t have the latest version of your operating system, it’s a good idea to update iOS to close this potential vulnerability. Just follow these steps: 

Go to Settings. 
Click on General. 
Click on Software Update. 
Follow the instructions to update your iPhone. 

Restart your device

It might sound simple, but restarting your device can fix certain issues. The system will restart on its own when updating the iOS. If you already have the latest version, restart your iPhone now. 

Clear your iPhone browsing history and data

If updating the iOS and restarting your device didn’t fix the issue, try clearing your phone’s browsing history and data. If you’re using Safari, follow these steps: 

Go to Settings. 
Click on Clear History and Website Data 
Click on Clear History and Data 

Keep in mind that the process is similar for Google Chrome and most other popular web browsers. 

Remove any suspicious apps

Malicious software, such as spyware and ransomware, often end up on phones by masquerading as legitimate apps. To err on the side of caution, delete any apps that you don’t remember downloading or installing. 

Restore your iPhone

The option to restore to a previous backup is one of the most valuable features found on the iPhone and iPad. Essentially, this allows you to restore your device to an iCloud backup made before the malware infection 

Here’s how: 

Go to Settings. 
Click on General. 
Click on Transfer or Reset iPhone. 
Choose Erase All Content and Settings. 
Choose Restore from iCloud Backup. 

Factory reset your iPhone

If none of the steps above solves the problem, a factory reset might be the next order of business. Restoring your phone to factory settings will reset it to its out-of-factory configuration, deleting all of your apps, content, and settings in the process and replacing them with original software only. 

To factory reset your iPhone, follow these steps: 

Go to Settings. 
Click on General.  
Click on Transfer or Reset iPhone 
Choose Erase All Content and Settings. 
Choose Set Up as New iPhone. 

How to keep your iPhone safe from malware

The best way to protect your iOS device is to avoid malware in the first place. Follow these security measures to safeguard your device: 

Don’t click on suspicious links. 
Don’t install apps that Apple doesn’t recognize. 
Only download apps from the App Store. 
Don’t jailbreak your iPhone, as this will remove most Apple security features. 
Enable automatic updates for iOS and iTunes to stay in line with Apple’s security updates and bug fixes. 
Keep frequent data backups. 
Avoid engaging with suspicious text messages on iMessage, as hackers use them to spread phishing scams. 

Secure your iPhone with McAfee Mobile Security 

If you have an iPhone and are like most other people, you probably use your device for almost everything you do online. And while it’s amazing to have the internet in the palm of your hands, it’s also important to be aware of online threats like malware, which can put your digital life at risk.

What Is a Data Broker?

Read Time:8 Minute, 41 Second

A data broker (also known as an information product company) is an organization that makes money by collecting your personal information, analyzing it, and licensing it out to be used by other companies for things like marketing purposes. 

Data providers gather data from many different sources to create a profile of who you are. This profile includes things like your interests, hobbies, demographics, and even the products you use.  

Generally, data broker companies only deal with customers to collect information. A few of the top data brokerage companies are Epsilon, Acxiom, and Experian, but there are many data brokerages worldwide that make a hefty profit from aggregating and distributing consumers’ personal data 

This article explains everything you need to know about data brokers, including what they do, how they get your information, and what you can do to limit the data they can access from you. 

Where do data brokers get your information?

There are several ways information brokers can get your information — both online and offline. 

Sources available to the public: Some of your personal records are easily available to the public. Data brokers can collect public records like your voter registration records, birth certificate, criminal record, and even bankruptcy records.  
Search history: Data brokers can track and analyze your browsing history to see things like what content you’re interested in and what demographics you fall into. You leave a trail that brokers can follow whenever you do anything online (like sign into a social media app, visit a website, or do a Google search). Using web scraping tools (software that pulls information from the web), it’s easy for data brokers to see what you’ve been up to online. 
Online agreements: You’ll usually have to sign an agreement when signing up for a new service online. Many of these agreements have disclosures in the fine print that give the company the right to collect and distribute your personal information. 
Purchase history: Data brokers want to know what products or services you’ve purchased, how you paid for them (credit card, debit card, coupon, or loyalty card, for instance), and when you purchased them. This information can be very valuable to marketing companies. 

Are data brokers illegal?

Generally, it’s legal for data brokers to get your information through public sources. However, different locations have different protections in place for consumers and different rules for how data brokers must operate. 

Many countries have laws to protect consumers from having their information shared without their consent. For example, the European Union has the General Data Protection Regulation (GDPR) to protect data privacy. The GDPR says data brokers need to get consent from consumers before sharing their information. The law also gives consumers the right to demand that companies delete any personal information that they have stored.  

On the other hand, the United States doesn’t have federal privacy laws protecting consumer information from data brokers. It’s up to the states to make their own laws. Some states prioritize consumer privacy more than others. For example, California has the Consumer Privacy Act, which gives customers the right to see what data a broker company has and the ability to delete it. 

Typically, companies ask for consent to share your information through the fine print of their agreements. You might not be aware of how much of your personal information you’ve allowed organizations to share.  

Who are the largest data brokers?

Data brokering is a huge industry. In fact, data brokers around the world bring in hundreds of billions of dollars a year. Here are some of the largest data brokerage companies that may collect your information.  

Epsilon Data Management, LLC: Businesses around the world rely on Epsilon for consumer data. The data management company has a massive database with details about millions of homes. You can request that your data not be collected by Epsilon on its website. 
Oracle America, Inc. (Oracle Cloud Data): Oracle is a technology conglomerate that designs and produces data network systems for businesses. Not only does Oracle team up with a large number of third-party data brokers, but the company also has its own database of consumer information. You can opt out of Oracle’s data collection program on their website. 
Acxiom, LLC: Acxiom is one of the largest data brokers. Acxiom collects a huge number of personal details about hundreds of millions of consumers from all over the world. For example, the broker might aggregate data like your political beliefs, health issues, and even your religious beliefs. Acxiom then sells information to businesses in sectors like finance or telecommunications. The company gives consumers the ability to opt out of its data collection program.  

Equifax Information Services, LLC: In addition to being a data broker, Equifax is one of the top three credit reporting agencies in the United States. The company collects consumer financial information that businesses can use to create targeted marketing campaigns. Investors can also use the information to gauge whether they should back an organization. To start the process of opting out of Equifax’s data collection program, you have to opt out of their marketing emails and their prescreened credit card offers. 
Experian, LLC: Experian is also one of the big three credit reporting bureaus in the United States. Like Equifax, Experian provides useful financial and personal information to both businesses and investors. Follow instructions on their website to opt out of Experian’s advertising program. You’ll need to opt out of their credit card offers separately.  
CoreLogic: CoreLogic collects information about things like which properties consumers own and how they spend their money. CoreLogic sells information to businesses and provides consumer data to real estate companies to help them screen potential tenants. You can opt out of CoreLogic on their website 

What personal information do data brokers collect?

By using various sources, data brokers can aggregate a lot of information about you. This information can be used to create user categories that businesses can market to. For instance, if you visit websites that sell baby products, the broker might put you into a category like “new parents.”  

Some of the information that brokers collect might be things you’d like to keep private. For example, a broker might collect sensitive data about health issues, past bankruptcies, or legal issues.  

Sometimes, brokers may place you in the wrong category. Let’s say you’re buying a new cookware set as a birthday gift for your mother. You check out several cooking sites before purchasing your set. If the broker sees that you’ve visited cooking sites and purchased cooking products, they may place you in a category like “cooking enthusiasts” even though you brought the gift for your mother. 

Here are some personal details that a broker can collect to create a consumer profile of you: 

Full name 
Gender 
Birthdate 
Contact information (like your phone number and email) 
Home address and where you’ve lived in the past 
Marital status and family situation, including children 
Social Security number (SSN) 
Level of education 
Assets 
Job 
Purchase habits 
Interests and hobbies 
Criminal record 
Political preferences 
Health history 

How data brokers use your information

Businesses are always looking for useful consumer information. Purchasing consumer data from brokers helps them tailor marketing campaigns to the demographics that are most likely to buy their products. 

Let’s say you’re a fan of virtual reality (VR) gaming. You’ve watched countless YouTube videos about the subject, and you’ve searched Amazon for VR headsets multiple times. You’d likely be an ideal consumer for a company that manufactures VR headsets or a company that creates VR games.  

Other companies might use your data for risk mitigation. For example, a bank might use your personal financial history to determine whether you’re likely to default on a mortgage loan.  

How to protect your data from data brokers

There are a variety of public records and sources that data brokers can use to gather information about you. The good news is that there are some things you can do to limit the amount of personal information they can access: 

Be selective about what you share online. Don’t overshare personal information on social media. Avoid things like online quizzes and sweepstakes.  
Use a virtual private network (VPN) whenever possible. A VPN hides your IP address and encrypts your data while you surf the web. McAfee’s Secure VPN protects your personal data and credit card information so you can browse, bank, and shop online without worrying about prying eyes (like data brokers). 
Use a Tor browser like the Tor Project or The Invisible Internet Project (I2P) to hide your actions online. Tor browser users remain anonymous online, but may sacrifice some connection speed.  

There are also a few organizations you can join to protect your information: 

Visit OptOutPrescreen.com. The Consumer Credit Reporting Industry site helps consumers opt out of prescreened credit card and insurance offers.  
Sign up for DMAchoice to get your name removed from telemarketing lists and direct marketing campaigns.  
Join the National Do Not Call Registry to avoid telemarketers.  

Discover how McAfee’s leading identity protection software can help

Data brokers are always looking for ways to get their hands on your personal information. Many reasons businesses want access to your personal data aren’t malicious. They simply want to provide you with a targeted advertising experience and introduce you to products you might like.  

 However, the more your personal information gets shared online, the more chances cybercriminals have to get their hands on it. There might also be some sensitive information you don’t want to share with businesses in general. If you’re careful about what you post and take steps to protect your cybersecurity, you’ll greatly reduce the amount of data that a broker can collect from you. 

With McAfee’s Total Protection services, you can get a secure online experience for your whole family. Our all-in-one protection suite comes with features like a secure VPN, premium antivirus software, identity monitoring, and up to $1 million in identity insurance and restoration.  

McAfee can help you safeguard data like financial records and health care information so you can have less stress online. You’re meant to enjoy the internet — and we’re here to help make that a reality.
