Daily tips to create awareness of cyber threats and empower Total Defense users to be safer and more secure online with our security tips and resources..
We’ve all been there: You find the perfect, specialty item from a new online shop. You click “Checkout,” and there it is—the dreaded prompt: “Create an Account to Continue.”
It’s tempting to hit “Yes.” They promise faster checkout next time and maybe even a coupon. But before you type in a password you’ll immediately forget, you need to ask yourself one question: Is this transaction worth a permanent digital connection?
For most one-off purchases, the answer is a resounding no. The best security decision you can make is choosing the Guest Checkout option. It’s one of the easiest ways to limit your risk across the internet.
Every time you create an account with an online vendor, you are handing over a valuable package of information: your email address, your name, your shipping details, and a new password you have to remember (or, worse, reuse).
Why is this risky? Because every single account you create represents a digital liability.
When you use Guest Checkout, you only provide the vendor with the bare minimum information needed to process the transaction and ship the item—usually just your email and shipping address.
Think of guest checkout as conducting a transaction in cash. You get the product, the store gets the payment, and there’s no long-term record tying your identity to their specific database.
This strategy works perfectly for:
By choosing Guest Checkout, you leave yourself with less to lose if that website is ever compromised. You never create an unnecessary password, and you prevent a new point of failure in your personal digital defense line.
The security mantra for online shopping should be: If you won’t shop there regularly, don’t register there permanently. Protect your private data and make guest checkout your new normal.
Remember the days of working in a corporate office? You were hooked up to a secure network managed by professionals, complete with firewalls and ironclad protocols. Now, for many of us, the “secure network” is just the Wi-Fi router sitting next to the TV.
This shift means you are now the primary security manager for your devices. And there’s one setting on your Windows computer that is often left wide open, silently inviting unauthorized eyes: File Sharing.
When file sharing is enabled on your Windows machine, it’s designed to make life easy—to let you quickly swap photos with a family member or print a document to a shared printer. But in a home environment, “easy” often equals “exposed.”
Your home network might be shared with multiple devices: your spouse’s laptop, your kids’ tablets, smart TVs, and maybe even a few smart speakers. While you trust your family, you can’t always trust the security of every device connected to your network. If even one device on your home Wi-Fi gets compromised by malware, that malware could potentially use your open file-sharing permissions to browse and copy files from your computer.
This is especially true if you handle sensitive information for work, like client data, financial reports, or proprietary business documents. You may have transitioned your laptop from a highly secure office network to a much less secure home setup. Turning off file sharing is a crucial step in recreating that professional barrier around your sensitive data.
The good news is that locking down file sharing is one of the quickest and most impactful security steps you can take. You don’t need to be a tech guru; you just need to know where to click.
Here is the quick process for modern Windows systems:
By turning off file sharing, you actively inhibit unauthorized individuals or malicious software on your home network from being able to peek into or steal files from your computer. It’s a small change with a massive impact on your privacy and security. Take two minutes today to check this setting and keep your sensitive files locked down!
Every time you pull out your physical credit card and type the numbers into a website, you are engaging in a risky activity. Think about it: you are handing over the keys to your financial life—your 16-digit card number, expiration date, and that critical three-digit code—to yet another online retailer.
But what if you never had to share your real credit card number again? That’s the power of the digital wallet, and it’s why services like Apple Pay and Google Pay are the smart, secure way to pay, both online and in brick-and-mortar stores.
When you manually type your credit card details, you expose that data to two major threats:
It’s a high-risk transaction that happens billions of times a day.
Digital wallets like Apple Pay and Google Pay solve this problem using a clever security technique called tokenization. Here’s how it works:
When you add your credit card to your digital wallet, the service doesn’t actually store your real card number on your phone or in their system. Instead, they create a unique, scrambled number called a token (also sometimes called a “virtual card number” or “device account number”).
When you make a purchase, the digital wallet sends this token to the retailer, not your real credit card number.
The security benefits of digital wallets extend to the real world, too. When you tap your phone or smartwatch at a register, the same tokenization process occurs. You’re not swiping a physical card that can be skimmed; you are wirelessly transmitting a secure, single-use token.
Many online shops, apps, and even major brick-and-mortar retailers now accept these forms of payment. By setting up and consistently using your digital wallet, you are actively choosing the most secure payment method available, essentially creating an armored shield around your financial data.
Make the switch today. Stop sharing your credit card number and start using the token. It’s the easiest security upgrade you’ll make all year!
That little buzz in your pocket often brings a moment of excitement: Your package is on its way!
We are constantly checking our phones, waiting for tracking updates, and anticipating that front-door delivery. Scammers know this anticipation is high, and they are masters at exploiting it. That’s why you need to be on high alert for a massive spike in delivery scam smishing.
“Smishing” is just a catchy term for SMS phishing. Phishing is the use of emails or messages designed to trick you. Since most of us have learned to spot a poorly-written email scam, criminals have shifted their game to text messages, where we tend to be less cautious.
A typical delivery smishing scam works like this:
The key to beating these scams is to adopt a simple, three-second rule: Never click on a link in an unsolicited text message.
Instead of clicking that link, follow these steps to verify any suspicious message:
amazon.com
into your browser) and check your “Your Orders” page. If there is a legitimate issue, it will be clearly posted there.Delivery scams succeed because they catch you when you’re distracted and expecting a delivery. By remaining skeptical, closing the message, and verifying information through official channels, you stop the scammer dead in their tracks. Protect your phone, and make sure your package is the only thing that arrives!
When you type a website address, or URL, into your browser, you probably don’t think much about the last few letters, right? That little suffix—the .com
, .org
, or .net
—is called a Top-Level Domain (TLD). For years, these TLDs were limited and very familiar. But the internet is a big place now, and new TLDs have exploded onto the scene, giving us options like .shop
, .tech
, and even .ninja
.
While many of these new extensions are perfectly legitimate, some have become digital red flags. You need to start paying attention to them, because they can be a quick indicator that you’re about to click into a dangerous neighborhood.
The problem is that the relaxed rules for creating and registering these newer TLDs have been widely exploited by cybercriminals. They love using fresh TLDs because it allows them to set up huge numbers of disposable, malicious websites very cheaply and quickly.
For example, reputable sites usually stick to the classic TLDs. A well-known company will be [Company].com
, not [Company].xyz
or [Company].download
. When you see one of the unusual TLDs, you should immediately raise your internal security alarm.
While you should exercise caution with any unfamiliar TLD, security experts have identified a few that are almost exclusively associated with suspicious or outright malicious activity, particularly spam distribution and malware downloads.
Be especially wary if you see these TLDs in your search results, in an email link, or in an unexpected pop-up:
Why these three in particular? They are often used to host drive-by download sites, where just visiting the page can start downloading malware, or they host spam and phishing content designed to trick you out of your personal information. If you encounter a link ending in one of these, do not click it.
Protecting yourself requires two simple, active steps:
By simply taking notice of the few letters at the end of a web address, you can significantly reduce your risk of stumbling into a cybersecurity trap. Keep an eye on those TLDs and keep your devices safe!
You’ve finished an important document, and now it’s time to share it with your team. What’s your first move? If you’re like many people, you might download the file and email it as an attachment, or maybe you grab the link and send it off.
While those methods might seem convenient, they introduce several major security risks and productivity headaches. Today, we’re going to show you why sharing directly through Google Docs is the smartest, safest, and most professional way to collaborate.
The most compelling reason to ditch email attachments is security. Email attachments are a classic technique commonly exploited by phishers.
Cybercriminals frequently send emails that look legitimate, complete with your company’s logo, asking you to “Review the attached file.” When you click on the attachment, you aren’t opening a PDF; you’re often downloading malicious software (like a virus or ransomware) onto your computer. These attacks work because people are conditioned to trust files that show up in their inbox.
By refusing to send or open email attachments for collaboration, you immediately close off one of the easiest ways for criminals to sneak malware onto your system.
If you use email attachments, you instantly create a messy problem called version control. When you send a file:
Suddenly, you have three different files in your inbox and no idea which one is the final, accurate document.
Sharing directly in Google Docs solves this. The document lives in one place (the cloud), and every edit is tracked in real-time. You always know you are working on the latest version.
Sharing directly from a Google Doc is fast, easy, and gives you total control over who sees your work. Here’s the secure method:
By sharing access instead of sending attachments, you preserve your editing permissions, maintain perfect version control, and, most importantly, protect yourself and your company from phishing attacks. Make this small change today for big security gains!
When you settle down for a weekend binge, you expect to see your profile—not random activity from a device you don’t recognize. While it might just be a friend sharing a password (bad habit, by the way!), an unrecognized device on your streaming account could be a red flag pointing to a much larger cybersecurity problem.
It’s time to take a quick, proactive step to protect your digital life, starting with your favorite streaming service.
Subscription services like Netflix, Hulu, Spotify, and others are prime targets for hackers. Why? Because most people reuse the same email and password combination for everything, including their bank and work accounts. If a hacker cracks your weak password or steals your credentials from a data breach at a different site, the first thing they do is test that combination on popular services like Netflix.
If they get in, they gain two things: free entertainment (annoying!) and confirmation that your password works—making your other, more important accounts vulnerable (terrifying!).
Stopping unauthorized access is simple. Netflix makes it easy to see exactly where your account has been active. You should get into the habit of checking this page at least once a quarter.
Here is the step-by-step process:
If you spot something suspicious, don’t panic. You have two crucial immediate actions to take:
By checking your streaming device activity, you’re doing more than just protecting your watch history; you’re using it as an early warning system to protect your entire digital life. Make it a routine and keep your accounts secure!
You’ve heard the term “computer virus” a thousand times. Maybe you got a pop-up warning, or perhaps a friend panicked when their laptop slowed to a crawl. But what exactly is a computer virus, and how does this digital infection manage to wreck so much havoc?
Let’s break down this pesky digital pest.
A computer virus is essentially a piece of malicious code that acts much like its biological namesake: it can’t live on its own. It needs a host—like a file, a program, or even the system area of your hard drive or network router—to exist.
Once it infects a file, the virus immediately starts its mission: spreading by making copies of itself. When you open the infected file, the virus springs into action, injecting its code into other files on your computer. When you share that file with a friend or upload it to a shared network, the virus jumps to new hosts, and the cycle continues.
Think of it like digital graffiti: once the virus gets the marker, it quickly scrawls its code onto every clean surface it can find.
Not all viruses are created equal, and their intent—or payload—can vary wildly. Some are relatively harmless annoyances, designed simply to spread and maybe display a quirky message on your screen. They might slow your system down by hogging resources, but they won’t necessarily damage your files.
However, many viruses are far more destructive. They can:
The key takeaway is this: regardless of their intent, viruses compromise the integrity of your computer system.
The good news is that protecting yourself from these digital bugs is straightforward. You don’t need a PhD in cybersecurity—you just need the right tools and good habits.
The single most effective shield you have is up-to-date antivirus software. This software acts as a digital immune system, constantly monitoring your files and scanning incoming data for known virus signatures. If a virus tries to sneak in, the antivirus catches it and isolates it before it can spread and cause damage.
A few simple habits also make a huge difference:
By understanding what a computer virus is and actively deploying your defenses, you take control of your digital security. Protect your devices today and keep your data safe!
