Unexpected 2FA Codes: Your Cybersecurity Wake-Up Call – 5/5/2024
We’ve all had those moments of confusion when our phone buzzes with a notification that doesn’t seem quite right. If you’ve ever woken up to a text with some random numbers and wondered what it is, you’re not alone.
Getting a code for two-factor authentication (2FA) from a service you use when you didn’t request one deserves some attention. Rather than ignoring the strange message, it’s a good idea to take action to help protect your online accounts.
Understanding 2FA
2FA, or “Two-Factor Authentication,” is an important security feature many apps and websites use. It adds an extra verification step beyond just a password. After you log in, 2FA will text or email you a special code to enter before you’re given access to your account. This acts like a second lock, keeping hackers out even if they somehow steal your password.
Spot the Warning Signs
When you receive a 2FA code you didn’t request, it’s a clear sign that someone is trying to access one of your online accounts. It often indicates that your password has been compromised through a large-scale data breach or a more targeted attack. Hackers may be attempting to log in using your stolen credentials, and the 2FA code is the only thing standing in their way.
Taking Immediate Action
Rather than ignoring the 2FA code or brushing it off, it’s important to take action right away to secure your accounts.
Do not click on any links in the email or SMS. Open a browser, log in to the relevant account, and change your password to something unique and complex. Make sure it’s different from the one you used before and not used for other accounts.
Check if your old password was involved in any known breaches using a tool such as HaveIBeenPwned.com. This can help you identify if you have any other accounts that may be at risk.
Consider changing passwords for any other accounts using the same or similar passwords in case of credential stuffing attacks. This is when hackers use stolen passwords from one breach to try and access other accounts.
Be wary of emails or texts asking you to provide a 2FA code. Legitimate services will never ask for this, and it’s likely a phishing attempt.
This unexpected 2FA code experience is a valuable reminder of the importance of proactive security measures. Two-factor authentication is what saved you this time by blocking the hacker’s attempt to access your account, so take a moment to ensure you’ve enabled it on every site that offers it.
Additionally, using unique, strong passwords for each account is essential to prevent the ripple effects of a single data breach. A password manager can help you generate and store complex credentials, ensuring one compromised password doesn’t put all your other accounts at risk.
While complete online security can never be guaranteed, taking these fundamental steps – enabling 2FA and using unique passwords – goes a long way toward safeguarding your personal information and digital identity.

How SIM Swaps Bypass Your Online Security, 5/2/2024
Have you ever been in the middle of an important phone call or task on your phone when you suddenly see those dreaded words, “SOS only” or “No Signal”?
Most of the time, it’s simply due to poor signal strength in your area or a temporary glitch with your carrier’s network. But what if losing your phone connection wasn’t so innocent?
What if an unknown hacker actively removes you from your mobile number to take it over for their own malicious purposes? This is the frightening reality of a cybercrime called “SIM swapping,” and it’s a growing threat that has affected many unwitting victims.
How Hackers Carry Out SIM Swapping
Hackers gather personal information, such as your name, date of birth, and address, through data breaches or social engineering. They then contact your mobile carrier with enough information about you to answer the verification questions. They impersonate you and claim to have lost your SIM card.
Mobile network carriers that don’t sufficiently verify customers often make it possible for a hacker to convince an employee to port your phone number to a new SIM card under their control.
This is done without triggering notifications to your devices or email addresses. Within minutes, you could find yourself disconnected from your mobile number while the hacker now receives all calls and texts intended for you. The whole process can be carried out remotely.
The Risks of Losing Access to Two-Factor Authentication
Once hackers control your phone number, they can bypass the two-factor authentication that protects many of your online accounts. Most major services send one-time verification codes via text when you attempt to log in from a new device. With your SIM swapped, these codes get diverted to the hacker.
This can then allow the hacker access to your emails, finances, cryptocurrency, and any other service that uses SMS-based two-factor authentication.
To make matters worse, restoring access to your accounts becomes a nightmare without your phone number.
Preventing SIM Swapping Attacks
Unfortunately, SIM swapping is not a new issue and may become even more prevalent as hackers develop more advanced techniques, such as deepfaking. However, there are some precautions you can take:
Do not share personal details unnecessarily online or over the phone. Be wary of attempts at social engineering.
Limit what information you make publicly available on social media profiles or in public records.
Use authentication apps such as Google Authenticator or Authy instead of SMS-based codes wherever possible.
Contact your mobile carrier and ask them to put a PIN or passcode on your account as an extra security step before any changes can be made.
By taking these steps, you can help protect yourself from having your phone number and online accounts compromised by SIM swapping.
Staying vigilant about cybersecurity is important for everyone in the digital age.
7 Effective Strategies to Avoid Spam Emails – 4/19/2023
Spam emails can be a nuisance, cluttering your inbox with unwanted messages and potentially exposing you to various risks, such as phishing attacks or malware. Thankfully, there are several strategies you can employ to avoid spam and keep your inbox clean. In this article, we will explore seven effective methods that can help you steer clear of spam emails.
Use a Reliable Email Provider
Choosing a reputable email provider is crucial for avoiding spam. Providers like Gmail, Outlook, or Yahoo Mail have advanced filters that automatically detect and redirect most spam emails to your junk folder. Consider switching to one of these providers if you’re currently using an unreliable email service.
Be Selective with Online Registrations
When signing up for online services or making purchases on the internet, be cautious about sharing your email address. Only provide it to trusted sources and take the time to read their privacy policies regarding data usage.
Don’t Reply or Click Suspicious Links
If you receive an unsolicited email from an unknown sender or a suspicious-looking message from someone claiming to be familiar, refrain from replying or clicking on any links within the email. These could lead you down the path of malware installation or phishing attempts.
Utilize Disposable Email Addresses
Consider using disposable email addresses when signing up for newsletters, promotions, or online forums where providing an email address is necessary but not necessarily trustworthy in terms of data protection.
Enable Two-Factor Authentication (2FA)
Enabling 2FA adds an extra layer of security by requiring a second verification step when logging into your accounts – typically through a text message code sent to your phone number associated with the account—which helps prevent unauthorized access even if spammers get hold of your login credentials via phishing attempts.
Regularly Update Your Antivirus Software
Keeping your antivirus software up-to-date is essential as it helps detect and block potential threats before they reach your inbox.
Be Mindful When Unsubscribing From Emails
While unsubscribing from unwanted promotional emails can be helpful, exercise caution when doing so; only unsubscribe from reputable sources that provide legitimate opt-out options in their emails’ footer section.
By following these strategies consistently and being vigilant about protecting yourself against spammers’ tactics, you can significantly reduce the amount of spam in your inbox and minimize potential risks associated with malicious content present in such emails.

Protect Yourself from Computer Scams: Stay Informed and Stay Safe – 4/18/2024
In this digital age, computers have become an integral part of our lives. Unfortunately, alongside the advancements in technology, computer scams have also become increasingly prevalent. These scams can result in financial loss, identity theft, and a breach of privacy. Therefore, it is crucial for individuals to be aware of the common types of computer scams and take preventative measures to protect themselves.
Phishing Computer Scams
Phishing scams are one of the most common forms of online fraud. They involve tricking individuals into revealing sensitive information such as usernames, passwords, or credit card details through deceptive emails or websites that appear legitimate. To avoid falling victim to such scams, always double-check the email sender’s address and avoid clicking on suspicious links.
Tech Support Computer Scams
Tech support scams often involve cold-calling unsuspecting victims and posing as tech support representatives from reputable companies like Microsoft or Apple. These scammers claim that your computer has been infected with malware or viruses and offer assistance at a price. Never give remote access to your computer unless you initiate contact with verified customer support channels.
Online Shopping Computer Scams
With the rise in e-commerce transactions comes an increase in online shopping scams. Fraudulent sellers may advertise products at incredibly low prices but fail to deliver upon payment confirmation or send counterfeit items instead. Be cautious when dealing with unknown sellers by checking their reviews and ensuring secure payment methods are used.
Lottery/Sweepstakes Computer Scams
Lottery or sweepstakes scams often target individuals by informing them they have won a large sum of money but require upfront fees for processing charges or taxes before releasing any funds. Remember that genuine lotteries do not require winners to pay any fees before receiving their winnings; if it sounds too good to be true, it probably is.
Imposter/CEO Fraud
Imposter fraud involves scammers impersonating high-ranking officials within organizations via email correspondence aimed at deceiving employees into sending money transfers under false pretenses like urgent business matters or emergency situations involving suppliers/customers/payments/etc.
To prevent falling prey:
a) Always verify email addresses carefully.
b) Implement dual authorization processes for financial transactions.
c) Train employees regularly on identifying fraudulent emails.
d) Establish clear protocols regarding sensitive financial information handling.
Conclusion
The digital world provides us numerous advantages but also exposes us to various cyber threats—including computer scams—that can wreak havoc on our personal lives and finances if we’re not careful.
By staying informed about the common types of computer scams and taking proactive measures to protect ourselves, we can greatly reduce the risk of falling victim to these malicious activities. It is crucial to remain cautious when navigating the online world, double-checking emails, verifying sources, and avoiding suspicious links or offers. By staying informed and staying safe, we can ensure that our computers remain a tool for productivity and enjoyment rather than a gateway for scams and fraud.

The Real Price of Cheap Printers Revealed – 4/5/2024
We’ve all been there – rushing to print an important document only to discover your inkjet printer is on the fritz yet again. Whether it’s refusing to print because the cartridges aren’t full enough or leaving streaks and lines across your documents, inkjet printers are notorious for acting up precisely when you need them most. Beyond the frustration, these constant issues could be costing you more than you realize.
The Hidden and Ongoing Costs of Inkjet Printing
On the surface, inkjet printers may seem like the more affordable printer option. However, printer manufacturers make their real profits through expensive replacement ink cartridges rather than the printers themselves. The cost of a set of new cartridges is often much higher than the actual printer.
What’s more, ink dries out quickly, which means cartridges need frequent replacement, even if you aren’t a heavy printer. All those replacement cartridges add up over time. Research shows the total lifetime cost of owning an inkjet can be double or even triple the initial purchase price once you factor in ink.
Constant Clogging and Drying Issues
One of the biggest frustrations of inkjet printing is the tendency for those tiny nozzles to clog if the printer sits idle too long. This is because inkjets deposit liquid ink onto the page through micro nozzles. If not used regularly, the ink inside can dry up and cause blockages.
Even printing just a few pages weekly may not be enough use to keep ink flowing freely. The result is streaks, lines, light prints or failures to print at all – right when you need it most. How much time have you wasted troubleshooting a clogged inkjet instead of working on important projects?
Laser Printers – A Low Maintenance Alternative
Laser printers work differently by using dry toner powder and an electrostatic printing process rather than liquid ink. This eliminates the clogging issues that plague inkjets.
Additionally, lasers are designed to sit idle for extended periods without issue. You can print confidently when that looming deadline arrives, knowing your laser printer will perform flawlessly—no more delays or frustrations caused by an unreliable inkjet.
What About Color Printing?
While inkjet printers provide the benefit of color printing, the need for color for most typical home use is quite low. Most common printing tasks like documents, homework assignments, bills, and other everyday papers rarely require color.
For the occasional photo or graphic needing color, it’s often more affordable to outsource those prints to a retail store rather than pay for expensive color inkjet cartridges.
Invest in Hassle-Free Printing
If your inkjet has become more trouble than it’s worth, it may be time to make the switch to a laser printer.
Contact us today at (651) 456-8655, or visit our Contact page, and I’ll help you choose a printer designed for reliability rather than constant repairs and cartridge replacements. Say goodbye to dried-out nozzles and streaky prints with a laser that’s always ready when you need it most. The total cost of ownership will be much less over the long run.
If your trusty home PC has started showing its age, with more issues cropping up lately, you may be wondering if it’s finally time to say goodbye to your old friend. Or could some TLC in the form of repairs get it back in the game?
We are often asked to help clients make this decision. Several important factors must be considered when determining the best path forward.
How Old Is It Really?
While it may seem like you just bought it yesterday, some computers have relatively short lifespans in technological terms. If your machine is more than 10 years old, it’s likely well past its prime. Parts can become difficult to source, and repair costs may exceed the original value.
What Issues Are Cropping Up?
Minor glitches that cause annoyance but don’t hamper use, such as a stubborn virus or faulty keyboard, can often be fixed for $50 – $150. On the other hand, multiple hardware failures, a dying motherboard, or other major component replacements indicate deeper underlying issues. For problems of that magnitude, repairs may cost 50% – 75% the price of a new comparable model.
Will Parts Be Readily Available?
Specific key components may go out of production after a few years, especially with aging laptops. If it’s determined that your motherboard, screen, or other vital piece needs swapping out, there’s a good chance we won’t be able to get a replacement. This significantly increases repair costs and turnaround time, due to custom orders or used-part sourcing.
How’s the Performance Over Time?
Modern computing demands continue to grow exponentially with each passing year. If your PC has been steadily slowing down over the last 6–12 months and is struggling to run even basic tasks, it may be time for an upgrade.
What’s Your Budget Situation?
For clients on a tight budget, we’re always willing to thoroughly diagnose issues and provide affordable repair options to squeeze out a little more usability from an older machine. However, if an attractive new model is realistically within your means, an upgrade may give you several more years of smooth sailing.
Let’s Diagnose Your Situation
Rather than taking guesses, we always recommend bringing your computer for a thorough diagnosis. We can carefully assess its overall condition, identify any underlying problems, provide repair estimates, and help you weigh up the costs and benefits of fixing versus upgrading based on your unique needs and budget.
With the right solution, you’ll be back to enjoying your computer for many more years to come! Call us today at (651) 456-8655 or visit my Contact page to send me a message.
Protecting Kids in the Evolving Digital Landscape, Patrick Jensen, 3/15/2024
From online bullying to inappropriate content, the internet poses unique risks to children that didn’t exist just a decade ago. While basic safety measures such as avoiding suspicious links and keeping personal details private are still necessary, today’s kids face a more complex threat landscape that demands continuous vigilance from parents.
Let’s take a closer look at some of the top concerns and what proactive steps you can take to shield your family.
In-Game Purchases and Loot Boxes
Many popular games and apps entice kids with in-game currencies and randomized “loot boxes” that can function similarly to gambling. Children can unwittingly spend real money with just a few intuitive taps without understanding its value. While some platforms have added parental controls, enforcement remains inconsistent.
The safest approach to avoiding unexpected in-game spending is to avoid entering payment details altogether and use only gift cards with set balances for your kids’ accounts.
Filtering Across All Devices
With smartphones and tablets in the hands of even the youngest children, they now have constant internet access well beyond the home computer. It’s critical to employ consistent, comprehensive content filters across all devices your family uses, from desktops to mobiles.
Depending on your child’s age and maturity, options range from white-listing only approved websites to selectively blocking categories such as adult content, violence, or social media. While some devices have built-in parental controls, third-party solutions often provide more customization and coverage for multiple connected products in one place.
Monitoring Screen Time, Activity and Mental Well-Being
Both mobile and desktop operating systems offer parental controls to view activity reports and limit when and for how long children can use technology.
You can restrict specific apps, games, and websites, helping guide them toward age-appropriate content and healthy screen habits. Regularly reviewing activity logs ensures tools are properly configured to reflect your family’s needs and values. It also allows the prompt addressing of any concerning online behavior before it negatively impacts their well-being or development.
Educating Children About Internet Safety
Alongside tools, open communication helps kids navigate the online world safely and responsibly. Discuss appropriate ways to interact with others online and how to handle seeing upsetting content or bullying. Explain the potential dangers of oversharing personal details.
Prioritizing Safety Shouldn’t Mean Sacrificing Learning
While online threats have grown more complex, so too have the educational benefits of technology for curious young minds. With the right balance of education and protection, families can experience all the internet has to offer while ensuring their children’s well-being remains the top priority.

If you’ve noticed your home internet experience declining recently, with Netflix frequently buffering, lag in online games, or spotty Wi-Fi coverage throughout the house, it may be time for an upgrade.
Before you get frustrated with the slowdowns and dropouts, let’s evaluate if a new router could resolve these issues. A modern model designed to handle today’s bandwidth-heavy demands may be just what you need to restore fast, seamless Wi-Fi where you need it most.
Slowing Performance as the Network Grows
In the last 5–10 years, home networks have seen exponential growth in connected devices. Where households once had only a computer or two, it’s now common to have 10 or more devices simultaneously using the router for streaming media, Web browsing, online gaming, and more.
This increased bandwidth demand stresses older routers that are not designed for high-traffic networks. They have less powerful processors, less memory, and less advanced chipsets than newer models. Over time, an aging router may struggle to keep up, resulting in lagging or buffering issues.
Frequent Disconnections and Requiring Reboots
If you’ve noticed your Wi-Fi signal cutting out regularly, forcing you to reboot the router to get reconnected, this is a telltale sign that the router may be on the way out.
Outdated Wireless Standards
The Wi-Fi standards supported by routers have advanced rapidly in the last five years alone. Older models may be capable of only slower legacy standards such as 802.11b/g or 802.11n, while newer devices take full advantage of the increased speeds that standards such as 802.11ac (Wi-Fi 5) and 802.11ax (Wi-Fi 6) provide.
It also leaves you vulnerable, as older standards have known security flaws that newer protocols have addressed.
Missing Security Updates
Wireless router manufacturers typically support a device with firmware security updates for around five years after its release. But after that point, if new exploits are discovered, your older router model may no longer receive patches, leaving it open to hacks and malware.
By upgrading to a currently supported model, you can ensure the latest bug and vulnerability fixes for years to come, keeping your home network protected as threats evolve.
Feeling left behind by your ISP router?
If your current router was supplied by your internet service provider (ISP) as part of the connection package, it was likely a very basic and low-cost model selected to meet the minimum functionality requirements.
While “free” at the time, these OEM routers are often underpowered for today’s needs. An independently purchased router gives you complete control to choose a model tailored to your specific usage scenarios, such as whole-home coverage, fast speeds, or robust parental controls, ensuring you get the most out of your broadband home network.
Is it time for an upgrade?
If any of the issues above seem familiar or you want a faster, more reliable network throughout your home, an upgrade to a new, higher-performance router is well worth the investment.

“What’s that password again? Wait, I changed it… Harrumph. I don’t remember!” We’ve all been there, sometimes many times a day. Password autofill on our Web browsers felt like the sun was shining on our online activity again. Sorry to tell you, but this convenience may not be entirely safe.
Most browsers will ask after you’ve entered a new password into a site or changed a password if you want it stored for you. That way, when you revisit that site, the browser can autofill the access credentials for you. It saves you the struggle of trying to keep all your passwords straight.
The problem is that some sites, including legitimate sites, can be compromised with a hidden form. You’ll never see it, but your browser will. So, it will autofill that form, and in clear, unencrypted text. This allows bad actors to capture your username and password without your knowledge.
Another risk? Irresponsible digital marketers may use hidden autofill forms to track your online activity. That’s done without your consent.
Using browser autofill with a password manager can also cause confusion, especially if your browser autofills, whereas the manager asks before filling in forms. Using both at the same time you also run the risk of duplicating passwords, which could make it difficult to track your passwords and increase the risk of security breach.
How to disable autofill
You can protect your passwords by disabling autofill on any browser you use:
On Microsoft Edge, go to Settings, then Profiles, then Passwords, and disable “Offer to save passwords.”
On Google Chrome, go to Settings, then Passwords, and disable “Offer to save passwords.”
On Firefox, open Settings, then Privacy & Security, then Logins and Passwords, and “Autofill logins and passwords.”
On Safari, from the Preferences window, select and turn off Auto-fill.
Can I keep using password managers?
A password manager, such as LastPass or 1Password, typically provides more security than browser autofill. Password managers have strong encryption algorithms to protect your login credentials, which means that even if your device is compromised, your passwords are safe.
Still, if the manager autofills your credentials, you face the same risks. Most password managers have autofill disabled by default. That’s good. Leave preemptive autofill off. You might see it called “Autofill on page load.” Keep that turned off, too.
Our advice? Use a password manager that requires you to click a box before it fills in your credentials. This action avoids your information from automatically populating a hidden form.

Mobile apps let us play, teach us, give us social media or music, and more. No wonder there were more than 142 billion downloads in 2022! Going to Google or Apple’s mobile stores to find the app you want feels safe, but even these heavy hitters can’t guarantee you’re downloading something secure.
Google and Apple do their best, but they are vetting many thousands of new apps submitted monthly. The vast majority of their offerings aren’t a threat, but some malicious apps can make it through.
What do malicious app downloads do?
Apps downloaded from mobile stores are typically more secure than your Web activity. On an app, you’re within a contained system, whereas on the Web, you click through various links and visit websites which could have viruses or malware.
Still, a malicious app can infect your smartphone and cause several issues:
Ad fraud. The app runs in the background and sends ad clicks to different websites. This runs down your battery and slows your phone activity.
Data theft. If you give a malicious app permission to cross the app/data divide, it could lead to information being stolen.
Browser hacking. The app may open website browsers that put you at risk of sharing sensitive data.
Apps access all your information (SMS, camera, contacts) and take control of your device.
Keep your mobile phone safe
When looking to download a mobile app, do your research. Look at the ratings and how many downloads it has had. Application reviews can also help you verify the credibility of the app. Check the logo and the name of the creator, too. You don’t want to install something from Microsaft instead of Microsoft.
Keep your mobile device’s operating system current. Installing the manufacturer’s updates can help cut your vulnerabilities.
Also, take a moment to review the permissions for that new app. There’s no reason a calculator app needs access to your entire address book and camera. If the app asks for too much access, it can be a good idea to delete it and look for another option.
Be wary if you decide to download an app directly from a website other than the app store. This is a greater risk. Plus, know that illegally pirating software or media is a real risk for viruses.
Also, keep an eye out for common signs of a virus on your phone such as:
other apps taking longer than usual to open or install;
phone battery running down faster than normal;
your monthly data usage increasing;
your contacts receiving odd messages from you via email, text, or social media.
