As an avid internet surfer, you’ve most likely heard of cookies. No, we’re not talking about the ones filled with chocolate chips. We’re talking about the ones that allow you to log in to your favorite websites. Cookies may impact your online security, so check out these tips to manage them and keep your online accounts safe.
Ever wonder how a website saves the items you placed in your shopping cart last week, even though you closed the tab before making the purchase? This is made possible by cookies. According to the Federal Trade Commission, a cookie is information saved by your web browser. When you visit a website, the site may place a cookie on your web browser so it can recognize your device in the future. If you return to that site later, it can read that cookie to remember you from your last visit, keeping track of your activities over time.1
Cookies come in either the first-party or third-party variety. There’s no difference between the two in how they function, but rather in where and how you encountered them. First-party cookies belong to sites you visited first-hand in your browser. Third-party cookies, or “tracking cookies,” generally come from third-party advertising websites.
Although cookies generally function the same, there are technically two different types of cookies. Magic cookies refer to packets of information that are sent and received without changes. Historically, this would be used to log in to a computer database system, such as an internal business network. This concept predates the modern cookie we use today.
HTTP cookies are a repurposed version of the magic cookie built for internet browsing and managing online experiences. HTTP cookies help web developers give you more personalized, convenient website experiences. They allow sites to remember you, your website logins, and shopping carts so you can pick back up where you left off from your last visit. However, cybercriminals can manipulate HTTP cookies to spy on your online activity and steal your personal information.
Cookie hijacking (also known as session hijacking) is typically initiated when a cybercriminal sends you a fake login page. If you click the fake link, the thief can steal the cookie and capture anything you type while on the fraudulent website. Like a phishing attack, cookie hijacking allows a cybercriminal to steal personal information like usernames, passwords, and other important data held within the cookie. If you enter your information while on the fake website, the criminal can then put that cookie in their browser and impersonate you online. They may even change your credentials, locking you out of your account.
Sometimes, criminals initiate cookie hijacking attacks without a fake link. If you’re browsing on an unsecured, public Wi-Fi connection, hackers can easily steal your data that’s traveling through the connection. This can happen even if the site is secure and your username and password are encrypted.
Because the data in cookies doesn’t change, cookies themselves aren’t harmful. They can’t infect computers with viruses or malware. But if your cookies are hijacked as part of a cyberattack, a criminal could gain access to your browsing history and use cookies as the key to enter your locked accounts. For example, a hacker may steal your identity or confidential company information, purchase items in your online shopping carts, or loot your bank account.
Preventing cookie hijacking attacks can allow you to browse the internet with greater peace of mind. Follow these tips to not only safeguard your personal information but to also enhance your browsing experience:
Make it a habit to clear your cookie cache regularly to prevent cookie overload, which could slow your search speeds. Also, almost every browser has the option to enable/disable cookies on your computer. So if you don’t want them at all, your browser’s support section can walk you through how to disable them.
Although it’s convenient to not have to re-type your credentials into a website you frequently visit, autofill features could make it easier for a criminal to extract your data with cookie hijacking. Plus, autofill is risky if your physical device falls into the wrong hands. To browse more securely without having to constantly reenter your passwords, use a password manager like McAfee True Key. True Key makes it so you only have to remember one master password, and it encrypts the rest in a vault protected by one of the most secure encryption algorithms available.
Strong, unique passwords for each of your accounts, updated regularly, offer ample protection against hackers. Multi-factor authentication (MFA) adds yet another layer of security by double-checking your identity beyond your username and password, usually with a texted or emailed code. When your accounts offer MFA, always opt in.
Criminals can hijack your cookies if you’re browsing on an unsecured, public Wi-Fi connection. To prevent a criminal from swiping your data, use a virtual private network (VPN), a service that protects your data and privacy online. A VPN creates an encrypted tunnel that makes you anonymous by masking your IP address while connecting to public Wi-Fi hotspots. This is a great way to shield your information from online spies while you’re banking, shopping, or handling any kind of sensitive information online.

Let’s play a game. Go to the Photos app on your phone and look at the total number of videos and images on your device – all those precious memories of family vacations, clips from your favorite concert, and countless snapshots of your furry companion. Next, open your laptop or desktop and check to see how many documents you have saved — perhaps all the research reports you have saved to defend your graduate thesis or an important slideshow you’re presenting to your boss on Monday. If you had to guess, would you say the total number of these various pieces of data is into the thousands? Now imagine if all this data was suddenly gone. What would you do?
You might be thinking, “That will never happen to me.” However, this situation is more common than you think. More than 60 million computers will fail worldwide this year, and over 200,000 smartphones are lost or stolen every year. That’s why we’re celebrating World Backup Day by sharing how you can properly back up your files and find peace of mind knowing that your data is safe and sound.
A backup is a separate copy of your important and sentimental digital files and information. Storing all that data in one place, like a personal computer or smartphone, can prove unsafe. Creating another copy of that data through a backup will ensure that it’s stored and kept safe somewhere else should your device get wiped or stolen.
It’s important to recognize that data loss isn’t something that only happens to huge corporations or unsuspecting victims in spy movies. Everyone is susceptible to data loss or theft and backing up that data is an easy step to protect all your information and prevent cybercriminals from taking what isn’t theirs.
Data is one of the most important assets in the modern world. As we illustrated earlier, people collect countless files that contain valuable information they want to keep safe. Luckily, there are two common and inexpensive ways that a user can store their data and their ever-important backups.
Although “the cloud” became a major buzzword years ago, its definition is still cloudy for some folks. The cloud exists in remote data centers that you can access via the internet. Any data you’ve uploaded to the cloud exists on dedicated servers and storage volumes housed in distant warehouses, often situated on campuses full of such warehouses. Data centers are owned by cloud service providers, who are responsible for keeping the servers up and running.
To keep your data physically safe from theft and destruction, and to make sure it’s available whenever you want to access it, data centers run extensive cooling systems to keep the electronics from overheating and have at least one backup generator in case of power outages. But how do they make sure that this data is secure in the cybersphere? Cloud systems use authentication processes like usernames and passwords to limit access, and data encryption to protect data that is stolen or intercepted. However, it’s important to remember that passwords can be hacked. Typically, the service provider holds the encryption keys to your data, meaning that rogue employees could, theoretically, access it. Likewise, your data could also potentially be searched and seized by government entities.
This begs the question: Trust or don’t trust? Because cloud storage companies live and die by their reputation, you can rest assured knowing that they go to great lengths to use the most advanced security techniques and provide the most reliable service possible. To help ensure the security of your data should you choose to store or back it up to the cloud, keep anything truly sensitive in a private cloud behind a firewall.
With an external hard drive, you can manually back up all your data and files yourself onto a physical device that you can access anytime. These drives are a reliable way to achieve data redundancy. An external hard drive doesn’t rely on internet access like cloud-based services and is an easy fix when transferring data to a new device. However, using external hard drives requires a more hands-on approach to backing up your data. It’s your responsibility to regularly perform backups yourself and store your hard drive in a safe location. While cloud solutions offer huge amounts of storage, storage space on hard drives are limited, so you may have to purchase more than one device. Look for an external drive with at least a terabyte of space to accommodate all your data, which tends to accumulate quickly.
As you’re cleaning out your garage and tidying up your home, take the same care to do some digital spring cleaning this World Backup Day. Give your devices, apps, and online accounts a good decluttering and gain more peace of mind knowing that all your valuable data is stored in a safe, secure place … and that you have a backup in case something goes awry. Remember, proactivity goes a long way toward shoring up your cybersecurity and protecting your information.
