What Are Tailgating Attacks and How to Protect Yourself From Them

By McAfee

Whether you’re spending time on the web or working in the office, you want peace of mind knowing that you are in a safe environment. While most of us know to take precautions when online — protecting ourselves from things like phishing attacks and other cyber threats — we should also attend to our physical security. 

One concern is tailgating — a social engineering attack where someone gets physical access to a business to take confidential information or do other harm. 

Here are some ways to protect yourself from tailgating attacks, such as an unauthorized person following you into a restricted area while on the job. 

What is a tailgating attack?

Tailgating is a type of social engineering attack where an unauthorized person gains physical access to an off-limits location — perhaps a password-protected area — where they might steal sensitive information, damage property, compromise user credentials or even install malware on computers. 

Piggybacking” is closely related to tailgating, but it involves consent from the duped employee. So, while a worker might be unaware that someone has tailgated them into a restricted area with piggybacking, the hacker might convince a worker to provide access because they are posing as, say, a delivery driver. 

Who’s at risk of tailgating attacks?

Companies, particularly at risk of being targeted by tailgating scams, include those: 

  • With many employees, often moving inside and out of the premises 
  • With multiple entrance points into a building 
  • That receive deliveries of food, packages, documents, and other things regularly 
  • That have many subcontractors working for them 
  • Where employees aren’t thoroughly trained in physical and cybersecurity protocols 

Generally speaking, companies with robust security systems in place — including using biometrics, badges, or other identity and information security measures — are better protected from tailgating and piggybacking attacks.  

But that’s not to say that some smooth-talking fraudster can’t talk someone into letting them in or finding some way around those protections. 

What are common tailgating methods?

Common types of tailgating attacks that you should be aware of on the job include:  

  • Someone walking behind you into a secure area, depending on your common courtesy to keep the door open for them 
  • A courier or delivery driver who aren’t what they seem 
  • Someone with their hands full of items to trick you into opening the door for them 
  • A person who claims they’ve lost their work ID or forgotten it at home, so that you grant them admittance 

How to protect yourself from tailgating attacks 

Protecting yourself from tailgating attacks is partly a matter of learning about the issue, raising your level of awareness on the job, and depending on your employer, putting in place more effective security systems.  

Some solutions include: 

Increased security training

Many companies know how to train employees to recognize, avoid, and cope with online security issues but may forget to provide the same diligence to physical security. How to spot and deal with threats should be part of this training, plus cultivating an awareness of surroundings and people who might be out of place.   

Management should offer a clearly stated security policy taught to everyone, which might insist that no one be allowed into a secure area without the proper pass or identification. As the security policy is updated, all employees should be aware of changes and additions. 

These security measures should be part of an overall protection program, like McAfee+, which includes antivirus software, a firewall, identity monitoring, password management, web protection, and more. 

Smart badges and cards

If you have a large business spread over several floors, it can be hard for employees to know who works there and who doesn’t, leaving them susceptible to tailgating and piggybacking attacks. Requiring smart badges and cards to access restricted areas can help cut back on unauthorized intrusions and provide better access control. 

Building fully staffed reception areas with dedicated security personnel could also be part of a larger security system. 

Biometric scanners

Biometric scanners are an even more advanced way to provide proper authentication for a worker’s identity. They scan a unique physical or audible feature of a person and compare it to a database for approved personnel.  

Examples of biometric security include: 

  • Voice recognition 
  • Iris recognition 
  • Fingerprint scans 
  • Facial recognition 
  • Heart-rate sensors 

Understanding social engineering

One reason people are vulnerable to physical and cyberattacks is that they lack education on social engineering and the kinds of threats it poses.  

Workers need to understand the full range of social engineering techniques and know-how to protect themselves, whether in their social media accounts or physical work environment.  

For their part, companies can use simulated phishing emails and tailgating attacks to raise awareness and underline how to follow protocols in dealing with them. 

Video surveillance

If there are many ways to enter a business, it may make sense to put video surveillance on all entrances. Advanced video surveillance systems can use artificial intelligence (AI) and video analytics to scan the faces of people entering and compare them to a database of employee features. 

Discover how McAfee can help keep devices secure from hacking

Whether at work or at home, people want to be secure from attacks by cybercriminals who seek to take personal information. 

To add a layer of security to all their connected devices — including computers, smartphones, and tablets — an increasing number of people are turning to the comprehensive coverage of McAfee+ 

Features range from advanced monitoring of possible threats to your identity, automatic implementation of virtual private networks (VPNs) to deal with unsafe networks, and personal data clean-up, removing your information from high-risk data broker sites. 

McAfee protection allows you to work and play online with greater peace of mind.

“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 Tell Whether a Website Is Safe or Unsafe

By McAfee

It’s important to know that not all websites are safe to visit. In fact, some sites may contain malicious software (malware) that can harm your computer or steal your personal contact information or credit card numbers.  

Phishing is another common type of web-based attack where scammers try to trick you into giving them your personal information, and you can be susceptible to this if you visit a suspicious site.  

Identity theft is a serious problem, so it’s important to protect yourself when browsing the web. Online security threats can be a big issue for internet users, especially when visiting new websites or following site links. 

So how can you tell if you’re visiting a safe website or an unsafe website? You can use a few different methods. This page discusses key things to look for in a website so you can stay safe online. 

Key signs of website safety and security

When you’re visiting a website, a few key indicators can help determine whether the site is safe. This section explores how to check the URL for two specific signs of a secure website. 

”Https:” in the website URL

“Https” in a website URL indicates that the website is safe to visit. The “s” stands for “secure,” and it means that the website uses SSL (Secure Sockets Layer) encryption to protect your information. A verified SSL certificate tells your browser that the website is secure. This is especially important when shopping online or entering personal information into a website. 

When you see “https” in a URL, the site is using a protocol that encrypts information before it’s sent from your computer to the website’s server. This helps prevent anyone from intercepting and reading your sensitive information as it’s transmitted. 

A lock icon near your browser’s URL field

The padlock icon near your browser’s URL field is another indicator that a webpage is safe to visit. This icon usually appears in the address bar and means the site uses SSL encryption. Security tools and icon and warning appearances depend on the web browser. 

Let’s explore the cybersecurity tools on the three major web browsers: 

  • Safari. In the Safari browser on a Mac, you can simply look for the lock icon next to the website’s URL in the address bar. The lock icon will be either locked or unlocked, depending on whether the site uses SSL encryption. If it’s an unsafe website, Safari generates a red-text warning in the address bar saying “Not Secure” or “Website Not Secure” when trying to enter information in fields meant for personal data or credit card numbers. Safari may also generate an on-page security warning stating, “Your connection is not private” or “Your connection is not secure.” 
  • Google Chrome. In Google Chrome, you’ll see a gray lock icon (it was green in previous Chrome versions) on the left of the URL when you’re on a site with a verified SSL certificate. Chrome has additional indicator icons, such as a lowercase “i” with a circle around it. Click this icon to read pertinent information on the site’s cybersecurity. Google Safe Browsing uses security tools to alert you when visiting an unsafe website. A red caution symbol may appear to the left of the URL saying “Not secure.” You may also see an on-page security message saying the site is unsafe due to phishing or malware. 
  • Firefox. Like Chrome, Mozilla’s Firefox browser will tag all sites without encryption with a distinctive marker. A padlock with a warning triangle indicates that the website is only partially encrypted and may not prevent cybercriminals from eavesdropping. A padlock with a red strike over it indicates an unsafe website. If you click on a field on the website, it’ll prompt you with a text warning stating, “This connection is not secure.” 

In-depth ways to check a website’s safety and security

Overall, the ”https” and the locked padlock icon are good signs that your personal data will be safe when you enter it on a website. But you can ensure a website’s security is up to par in other ways. This section will explore five in-depth methods for checking website safety. 

Use McAfee WebAdvisor

McAfee WebAdvisor is a free toolbar that helps keep you safe online. It works with your existing antivirus software to provide an extra layer of protection against online threats. WebAdvisor also blocks unsafe websites and lets you know if a site is known for phishing or other malicious activity. In addition, it can help you avoid online scams and prevent you from accidentally downloading malware. Overall, McAfee WebAdvisor is a useful tool that can help you stay safe while browsing the web. 

Website trust seals

When you’re browsing the web, it’s important to be able to trust the websites you’re visiting. One way to determine if a website is trustworthy is to look for trust seals. Trust seals are logos or badges that indicate a website is safe and secure. They usually appear on the homepage or checkout page of a website. 

There are many types of trust seals, but some of the most common include the Better Business Bureau (BBB) seal, VeriSign secure seal, and the McAfee secure seal. These seals indicate that a third-party organization has verified the website as safe and secure. 

While trust seals can help determine whether a website is trustworthy, it’s important to remember that they are not foolproof. Website owners can create a fake trust seal, so it’s always important to do your own research to ensure a website is safe before entering personal information. 

Check for a privacy policy

Another way to determine if a website is safe to visit is to check for a privacy policy. A privacy policy is a document that outlines how a website collects and uses personal information. It should also state how the site protects your data from being accessed or shared by scammers, hackers, or other unauthorized individuals. 

If a website doesn’t have a privacy policy, that’s a red flag that you shouldn’t enter any personal information on the site. Even if a website does have a privacy policy, it’s important to read it carefully so you understand how the site uses your personal data. 

Check third-party reviews

It’s important to do some preliminary research before visiting a new website, especially if you’re shopping online or entering personal data like your address, credit card, or phone number. One way to determine if a website is safe and trustworthy is to check third-party reviews. Several websites provide reviews of other websites, so you should be able to find several reviews for any given site.  

Trustpilot is one example of a website that provides reviews of other websites. 

Look for common themes when reading reviews. If most of the reviews mention that a website is safe and easy to use, it’s likely that the site is indeed safe to visit. However, if a lot of negative reviews mention problems with viruses or malware, you might want to avoid the site. 

Look over the website design

You can also analyze the website design when deciding whether a website is safe to visit. Look for spelling errors, grammatical mistakes, and anything that appears off. If a website looks like it was made in a hurry or doesn’t seem to be well-designed, that’s usually a red flag that the site might not be safe. 

Be especially careful of websites that have a lot of pop-ups. These sites are often spammy or contain malware. Don’t download anything from a website unless you’re absolutely sure it’s safe. These malicious websites rarely show up on the top of search engine results, so consider using a search engine to find what you’re looking for rather than a link that redirects you to an unknown website. 

Download McAfee WebAdvisor for free and stay safe while browsing

If you’re unsure whether a website is safe to visit, download McAfee WebAdvisor for free. McAfee WebAdvisor is a program that helps protect you from online threats, such as malware and viruses. It also blocks pop-ups and other intrusive ads so you can browse the web without worry. Plus, it’s completely free to download and use.

How Do Hackers Hack Phones and How Can I Prevent It?

By McAfee

How do hackers hack phones? Several ways. Just as there are several ways you can prevent it from happening to you. 

The thing is that our phones are like little treasure chests. They’re loaded with plenty of personal data, and we use them to shop, bank, and take care of other personal and financial matters—all of which are of high value to identity thieves.  

However, you can protect yourself and your phone by knowing what to look out for and by taking a few simple steps. Let’s break it down by first taking a look at some of the more common attacks.  

Types of Smartphone Hacks and Attacks 

Hacking software 

Whether hackers sneak it onto your phone by physically accessing your phone or by tricking you into installing it via a phony app, a sketchy website, or a phishing attack, hacking software can create problems for you in a couple of ways: 

  • Keylogging: In the hands of a hacker, keylogging works like a stalker by snooping information as you type, tap, and even talk on your phone.  
  • Trojans: Trojans are types of malware that can be disguised in your phone to extract important data, such as credit card account details or personal information. 

Some possible signs of hacking software on your phone include: 

  • A battery that drains way too quickly. 
  • Your phone runs a little sluggish or gets hot. 
  • Apps quit suddenly or your phone shuts off and turns back on. 
  • You see unrecognized data, text, or other charges on your bill.   

In all, hacking software can eat up system resources, create conflicts with other apps, and use your data or internet connection to pass along your personal information into the hands of hackers—all of which can lead to some of the symptoms listed above. 

Phishing attacks 

These are a classic form of attack. In fact, hackers have leveled them at our computers for years now too. Phishing is where hackers impersonate a company or trusted individual to get access to your accounts or personal info or both. And these attacks take many forms, like emails, texts, instant messages, and so forth, some of which can look really legitimate. Common to them are links to bogus sites that attempt to trick you into handing over that info or that install malware to wreak havoc on your device or likewise steal information. Learning how to spot a phishing attack is one way to keep yourself from falling victim to one. 

Bluetooth hacking 

Professional hackers can use dedicated technologies that search for vulnerable mobile devices with an open Bluetooth connection. Hackers can pull off these attacks when they are range of your phone, up to 30 feet away, usually in a populated area. When hackers make a Bluetooth connection to your phone, they can possibly access your data and info, yet that data and info must be downloaded while the phone is within range. As you probably gathered, this is a more sophisticated attack given the effort and technology involved. 

SIM card swapping 

In August of 2019, the CEO of Twitter had his SIM card hacked by SIM card swapping scam. SIM card swapping occurs when a hacker contacts your phone provider, pretends to be you, and then asks for a replacement SIM card. Once the provider sends the new SIM to the hacker, the old SIM card will be deactivated, and your phone number will be effectively stolen. This means the hacker has taken control of your phone calls, messages, and so forth. This method of hacking requires the seemingly not-so-easy task of impersonating someone else, yet clearly, it happened to the CEO of a major tech company. Protecting your personal info and identity online can help prevent hackers from impersonating you to pull off this and other crimes.  

Ten tips to prevent your phone from being hacked 

While there are several ways a hacker can get into your phone and steal personal and critical information, here are a few tips to keep that from happening: 

  1. Use comprehensive security software on your phone. Over the years, we’ve gotten into the good habit of using this on our computers and laptops. Our phones? Not so much. Installing security software on your smartphone gives you a first line of defense against attacks, plus several of the additional security features mentioned below. 
  2. Update your phone and its apps. Aside from installing security software, keeping current with updates is a primary way to keep you and your phone safe. Updates can fix vulnerabilities that cybercriminals rely on to pull off their malware-based attacks. Additionally, those updates can help keep your phone and apps running smoothly while also introducing new, helpful features. 
  3. Stay safer on the go with a VPN. One way that crooks can hack their way into your phone is via public Wi-Fi, such as at airports, hotels, and even libraries. These networks are public, meaning that your activities are exposed to others on the network—your banking, your password usage, all of it. One way to make a public network private is with a VPN, which can keep you and all you do protected from others on that Wi-Fi hotspot.  
  4. Use a password manager. Strong, unique passwords offer another primary line of defense. Yet with all the accounts we have floating around, juggling dozens of strong and unique passwords can feel like a task—thus the temptation to use (and re-use) simpler passwords. Hackers love this because one password can be the key to several accounts. Instead, try a password manager that can create those passwords for you and safely store them as well. Comprehensive security software will include one. 
  5. Avoid public charging stations. Charging up at a public station seems so simple and safe. However, some hackers have been known to “juice jack” by installing malware into the charging station. While you “juice up,” they “jack” your passwords and personal info. So what to do about power on the road? You can look into a portable power pack that you can charge up ahead of time or run on AA batteries. They’re pretty inexpensive and easy to track down.  
  6. Keep your eyes on your phone. Preventing the actual theft of your phone is important too, as some hacks happen simply because a phone falls into the wrong hands. This is a good case for password or PIN protecting your phone, as well as turning on device tracking so that you can locate your phone or even wipe it remotely if you need to. Apple provides iOS users with a step-by-step guide for remotely wiping devices, and Google offers up a guide for Android users as well.  
  7. Encrypt your phone. Encrypting your cell phone can save you from being hacked and can protect your calls, messages, and critical information. To check if your iPhone is encrypted can go into Touch ID & Passcode, scroll to the bottom, and see if data protection is enabled (typically this is automatic if you have a passcode enabled). Android users have automatic encryption depending on the type of phone. 
  8. Lock your SIM card. Just as you can lock your phone, you can also lock the SIM card that is used to identify you, the owner, and to connect you to your cellular network. By locking it, keeps your phone from being used on any other network than yours. If you own an iPhone, you can lock it by following these simple directions. For other platforms, check out the manufacturer’s website. 
  9. Turn off your Wi-Fi and Bluetooth when not in use. Think of it as closing an otherwise open door. There are several attacks that a dedicated and well-equipped hacker can make on devices where Wi-Fi and Bluetooth are open and discoverable. Likewise, while not a hack, some retailers will track your location in a store using Bluetooth technology for marketing purposes—so switching it off can protect your privacy in some situations as well. You can easily turn off both from your settings and many phones let you do it from a pulldown menu on your home screen as well. 
  10. Steer clear of third-party app stores. Google Play and Apple’s App Store have measures in place to review and vet apps to help ensure that they are safe and secure. Third-party sites may not have that process in place. In fact, some third-party sites may intentionally host malicious apps as part of a broader scam. Granted, cybercriminals have found ways to work around Google and Apple’s review process, yet the chances of downloading a safe app from them are far greater than anywhere else. Furthermore, both Google and Apple are quick to remove malicious apps once discovered, making their stores that much safer.

Encrypted Messaging Service Hack Exposes Phone Numbers

By McAfee

Many people opt for encrypted messaging services because they like the additional layers of privacy they offer. They allow users to message their closest friends, family, and business partners without worrying about a stranger digitally eavesdropping on their conversation. The same people who message over encrypted services and apps are likely also diligent with securing their internet connections and using a VPN. 

Despite all those safeguards, everyday people are left in the lurch when the companies with which they entrust their information are victims of cyberattacks. That was the case for users of the encrypted messaging app, Signal. Due to a phishing attack and subsequent leak of customer phone numbers, people are looking to identify potential consequences, protect themselves from SIM swapping, monitor their identity, and take measures to make sure their information is safe in the future. 

What Happened?  

A recent cyberattack targeted Signal, an end-to-end encrypted messaging service.1 The attackers exposed about 1,900 phone numbers belonging to Signal users. While other personally identifiable information (PII), message history, and contact lists were spared, valid phone numbers in the hands of a cybercriminal can be enough to wreak havoc on affected users.  

It is likely that another recent and successful phishing scheme at Twilio was the entry point for the Signal hackers. (Signal partners with Twilio to send SMS verification codes to people registering for the Signal app.) At Twilio, phishers tricked employees into divulging their credentials. 

To rectify the situation and protect users, Signal is contacting affected users and asking them to re-register their devices. Also, the company is urging all users to enable registration lock, which is an additional security measure that requires a unique PIN to register a phone with Signal.  

Lessons Learned

There are many lessons not only companies but everyday people can learn from the Signal and Twilio hacks. Here are some ways you can take action at the first signs of a compromised phone number and to help prevent cyber-events like this from happening to you.  

Know the signs of SIM swapping 

SIM swapping occurs when a cybercriminal gets ahold of your cellphone number and a few other pieces of your PII and registers your phone number to a device and a new SIM card that isn’t yours. If they successfully reregister your phone number, they can then access your data, change account passwords, and lock you out of your most important accounts. 

Luckily, since most of us use our phones every day, SIM swapping is usually detected quickly. If your phone isn’t connecting to the network and you’re not receiving calls and texts, it could be a sign that your wireless provider may have reassigned your number to an impersonator. In this case, contact your wireless provider immediately. 

To make SIM swapping nearly impossible, always turn on multifactor authentication. Also known as MFA, multifactor authentication is a method many online accounts use to ensure that only the authorized user can gain entry. This could entail sending a one-time code by email or text, prompting security questions, or scanning for fingerprint or facial recognition in addition to asking for the account password. MFA is an additional layer of security that’s quick to implement. The extra few seconds it takes to type in a code or stand still for a facial scan is well worth the frustration is causes cybercriminals.  

Be selective with whom you share your PII

These days, everyone has dozens of online accounts for everything from banking and shopping to streaming services and gaming. Since you can’t predict which company is going to be breached next, limit the number of possible doors a cybercriminal could break through to access your PII. In the Signal hack, it was their third-party vendor that was likely the cause of the leaked phone numbers. This unpredictability means it’s best to limit sharing your PII with as few accounts as possible. A great practice is to regularly organize your online accounts and deactivate the ones you no longer use. 

Never share your passwords 

A phishing attack seems to have been the first domino to fall in the Twilio and Signal incident. It could’ve been prevented if everyone followed this absolute rule: Never share your password! Your employer nor your bank nor the IRS, for example, will ever ask you for your password to an online account. If you receive correspondence asking you to share your password, no matter how official it looks, do not comply.  

Phishers often lace their electronic correspondences with an urgent or authoritarian tone, threatening severe consequences if they don’t receive a response within a short timeframe. This is a ploy to get people to act too quickly without thinking through the request. If you receive a message that outlines dire consequences for seemingly small infractions, step away from the message for at least 15 minutes and think it through. Stay calm and follow up through official channels, such as a listed phone number on the organization’s website or a customer service chat room, to iron out the alleged situation instead.

Who loves tax season besides accountants? Hackers

 It’s tax time in the United States, and even if you’re pretty sure you did everything right, you’re worried. Did I file correctly? Did I claim the right deductions? Will I get audited? Unfortunately, tax season brings out scammers eager to take advantage of your anxiety.

The tax scam landscape

First, know that you’re probably doing a good job with your taxes. Less than 2% of returns get audited and most discrepancies or adjustments can get handled easily if you address them promptly.

Still, wariness of the IRS and intricate tax laws makes for ripe pickings when it comes to hackers, who prey on people’s fear of audits and penalties. Common scams include fake emails, phone calls from crooks posing as IRS agents, and even robocalls that threaten jail time. With the information they get from you, hackers can take things a step further by stealing your identity and filing tax claims in your name.

As if we didn’t have enough to worry about at tax time.

The good news is that you have plenty of ways to protect yourself from hackers. Check out these tips to stay safe this tax season.

The IRS Dirty Dozen: 12 tax-season scams

Straight from the authority itself, the IRS has published its top 12 tax season scams with new warnings brought on by the events of 2020.

For example, new to this year are scams associated with stimulus checks sent out by the government. The IRS says they have seen “… a tremendous increase in phishing schemes utilizing emails, letters, texts and links. These phishing schemes are using keywords such as “coronavirus,” “COVID-19” and “Stimulus” in various ways.”

This is very important: The IRS does not use email. If you get an email from someone saying they are the IRS and they want to talk with you about a problem, it is a scam.

Here’s what the IRS has to say:

The IRS will never initiate contact with taxpayers via email about a tax bill, refund, or Economic Impact Payments. Don’t click on links claiming to be from the IRS. Be wary of emails and websites − they may be nothing more than scams to steal personal information.

Social media attacks also made the IRS Dirty Dozen. In a social media attack, scammers harvest information from social media profiles. Hackers use the information to gain access to your online accounts in social media and beyond, like your bank account. Make it hard for them. Make your social media profiles private so that only friends and family can see them. Also consider so you can be safer from these kinds of crimes.

Get an email or call from the IRS? Here’s how to know if it was legit.

When a hacker poses as an IRS agent, they try to get personal information from you, like your social security number. They might demand payment, sometimes under the threat of penalties or even jail time. These strong-arm tactics are a dead giveaway that the email or phone call is fake.

What will the IRS do? Usually, the IRS will first mail a bill to any taxpayer who owes taxes. IRS collection employees might call on the phone or make an unannounced visit to your home or business. If they require a payment, the payment will always be to the U.S. Treasury. Read about other ways to know what the IRS won’t do when they contact you.

And remember: the IRS does not use email to contact you about tax problems.

File A.S.A.P. and check your credit report

A good defense is a good offense. File early. Protect yourself by filing your claim before they have a chance to file one as you. You don’t want to be one of those identity theft victims who finds out you’ve been scammed when you file your taxes only to get a notice in the mail saying your tax claim has already been filed.

Here’s other tool that can help you fight identity theft. And get this: it’s not only helpful, it’s free.  Through the Federal Trade Commission, you are entitled to a free copy of your credit report from each of the three major credit reporting companies once every 12 months. In this report, you can find inaccuracies in your credit or evidence of all-out identity theft.

Keep in mind that you get one report from each of the reporting companies each year. That works out to three reports total in one year. Consider this: if you request one report from one credit reporting company every four months, you can spread you free credit report coverage across the whole year.

Security software can help you protect your digital wellness

The idea is that, just like with your physical wellness, there are lots of steps you can take to protect your digital wellness. We’ve covered some of those steps in this blog. Consider one more: protect your digital life with a holistic security solution like McAfee Total Protection so you can enjoy life online knowing your precious data is protected. Tax time or otherwise, security software is always a smart move.
