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.

Spyware is tricky. Some types notify users that they’re monitoring activity. Others function in stealth mode and use the information they collect for nefarious purposes. Spyware is a type of software that collects data about online users and reports it to a company or an individual. What just about everyone can agree on is that anonymous browsing is looking more and more appealing and is likely the way of the future.
Here’s more about the types of spyware, which types are legal, and how you can scrub your device and live more confidently online.
Here are a few types of spyware and facts about each:
Is it legal? Definitely not!
What is its purpose? Criminal
Keyloggers are the most intrusive of the spyware variations. It does exactly as its name suggests: It takes note of keyboard strokes, logs them, and reports to the owner of the nefarious software. Once the cybercriminal has digitally looked over your shoulder at your online activity, they make note of your passwords, walk into your online accounts, and pilfer your private personal information. They could use this information to gain entry to your online bank accounts or steal your identity.
Keyloggers are downloaded onto devices (cellphones, tablets, laptops, or desktop computers) without the user’s knowledge. Cybercriminals can hide them within email attachments or in malicious web pages. So, the best way to steer clear of keyloggers is to never download attachments you’re unsure about and don’t visit sites that seem unprofessional. One rule of thumb is to mostly stick to URLs that begin with https and include a lock icon. These sites are almost always secure.
To determine if your device is infected with a keylogger, check your system’s performance. Is your device running slowly? See if there are any spikes in activity or unknown programs running in the background. This could indicate that your device is hosting a malicious program.
Is it legal? Sometimes
What is its purpose? Advertising and criminal
Adware is categorized as a type of spyware. It tracks users’ online activity and spits out targeted pop-up advertisements. If you have the pop-up blocker enabled on your browser, you’ll likely be spared from the annoyance. Additionally, pop-ups can slow your device, so that’s another reason to turn on the pop-up blocking feature. Legitimate adware often asks users to opt into targeted ads.
Adware turns malicious (and illegal) when it contains malware. Sometimes cyber criminals hide malware within pop-ups. It’s easy to accidentally hit a link within a pop-up when you’re aiming quickly for the X to close it.
It’s easy to spot a device with an adware infestation. First, the number of pop-ups will be out of control. Also, the device will crash often, run very slowly, and have a short battery life. An antivirus program will likely be able to identify and remove the culprit. You can also check out your system monitor and end tasks that are draining your device’s power.
Is it legal? Yes
What is its purpose? Advertising
Cookies are delicious, especially to advertisers who use them to better target ads and make profits selling collected user data to third-party companies. Cookies are sometimes categorized as spyware, because they log the websites you visit and report them. You may notice the banners on websites that ask you to accept cookies.
Many users today are uneasy with sharing their online activity with strangers and advertisers. Sometimes the ads that pop up on your social media feed or in sidebars seem a little too targeted and it feels like someone is listening in to your conversations and attempting to make a profit from them.
