SIM Jacking, What is it and Why Should You Care? – 12/27/2022
If you play the popular SIMS life-simulation video game, you could think SIM jacking means someone takes over your characters, but the reality is even worse. SIM jacking is a type of identity theft targeting your real-life identity via your phone.
In SIM jacking a bad actor uses the subscriber identity module (SIM) card associated with your cellphone number to make calls, send texts, and use data. This has several potential negative outcomes:
Your phone bill goes off the charts with international calling and data usage fees.
They might impersonate you by sending texts to scam your friends and family.
They can sign up for new email and social media accounts using your phone number.
Most importantly? They can use your phone number and SIM card to sign into your personal accounts. Many of us use text messaging for authentication. That’s when a site, say your bank, sends a code to your phone to confirm it’s you.
Now, imagine the criminal has access to your bank account through a leaked password. Whereas they couldn’t get in before because of two-factor authentication, they now have your SIM card, too. That means the SMS to authenticate your account also goes to them. They’re in, and you’re out.
How Does SIM Jacking Work?
Typically it starts, as so many cyberattacks do, with phishing. You might get a text or email that looks like it is from the cellphone carrier that asks you to click on a link. It might tell you there’s been suspicious activity on your account or that your bill is past due. It’s usually something that will make you anxious and feel the need to act urgently.
You’re taken to a fake website where you provide your name, address, cell phone number, and date of birth. With the right information, the scammer contacts your phone carrier and asks for a new SIM card. Once they have that in hand, they access your account and take over your cellphone. If they pair that with leaked credentials, they can really do damage.
If you’ve been SIM jacked, you’ll find out after the fact. You will no longer have a signal connection, so you won’t be able to send texts or make or receive calls. You may also have difficulty signing into the hacked accounts.
If you do think you’ve been SIM jacked, contact your carrier ASAP. Also, change your passwords and let your friends and family know. Otherwise, they might fall victim to a malware attack that appears to come from you.
Protect Yourself from SIM Jacking
Be careful with your personal information. Be wary of any requests to share your sensitive information online. Avoid taking action based on text messages or emails from people you don’t know and trust.
Protect yourself by using an authentication app such as Google Authenticator or Authy. Do this instead of using text messages to authenticate yourself online.
Always update the applications on your smartphone. Yes, it seems like there are constantly new updates, but they can be protecting you from vulnerabilities.
You might also get a request to restart your phone. This is a common sign your SIM card has been hacked. If you do it, you’ll lose control of your SIM card. So, call your carrier first.
It’s also a good idea to regularly review your phone bills for any charges that you don’t recognize.

You may not think about it much, but your computer needs a graphics processing unit (GPU). The GPU allows you to see multimedia content and renders the graphics of your video games. It can also accelerate high-performance computing. The good news? It’s no longer as difficult to get a new graphics card at a reasonable price.
A global shortage of GPUs in 2021 made it challenging to obtain new graphics cards. That could stall repairs and upgrades. Plus, people who wanted to build their own computers struggled to do so. If you did find a GPU available, you could expect to pay much more than usual. Scalpers were also buying the chips up and charging exorbitant prices.
One problem was that major chip manufacturers were struggling to source silicon. It’s needed for the semiconductor functionality of GPUs. The pandemic slowed and even stopped production at some of the largest silicon manufacturers.
It didn’t help any that cryptocurrency miners were buying up GPUs, too. They needed the processing power to mine efficiently.
Why the GPU shortage is over
Fortunately, the GPU storage is ending. GPU manufacturers continued developing chips while waiting for the silicon semiconductors they needed. Now that those are back online, the graphics card companies can quickly make up for lost time.
At the same time, GPUs are no longer the best option for cryptomining. Instead, they have been replaced by more efficient application-specific integrated circuits (ASICs).
What happens next?
Actually, a surplus of older GPUs is expected, as a new generation of GPUs has arrived.
A new GPU series means manufacturers and computer parts stores will look to clear inventory. They’ll want to sell off older GPUs to make room for the new product.
This can be good news. You can expect prices of the previous generation of technology to come down. Plus, you can take advantage of the GPU surplus to replace a failing GPU. Or you can now upgrade your graphics card more affordably.

Big-box stores have big names and aisles of computers on offer. They post tempting deals on pre-built computers. But how does buying one of those computers compare to purchasing a custom-built one?
When you shop in a big-box store, you are one of the many people those salespeople are going to work with in a day. If you’re lucky, you may get to speak with someone actually assigned to the computer area on a regular basis.
Working with us to customize a computer, you get individualized expert service. Our specialists know computer users have different needs. You deserve a computer that matches what you’re trying to do. You might want to run the latest-and-greatest games at full graphic quality. Someone else wants something basic to support only email and Web surfing. Or how about a stock day trader who doesn’t need a fast computer but wants to run six screens at once?
It may be easier to walk into a big-box store and walk out with a desktop computer, but the big-box computer aims to appeal to everyone; it isn’t customized to each of these different aims.
Problems with Pre-Built Computers
The computers sold for less in big-box stores have cut corners to bring down costs. They can use lower-quality parts. There’s also limit to upgradability of the parts. Prebuilt brand-name systems often use proprietary parts unique to that manufacturer. This makes it difficult and expensive to replace a part.
You could end up saving money by paying for a system that has only 4 GB of RAM. Sure, the sticker price was lower, but your computer won’t run as well. Today, you need a computer with at least 8 GB of RAM. Depending on how you plan to use the computer, we might even suggest 16 GB.
The big-box stores sell computers from brand-name manufacturers pre-loaded with bloatware. The manufacturer keeps prices down by installing unwanted software in return for kickbacks. So, you paid less, but your computer runs slower from day one because it’s brimming with software you didn’t want. A customized computer comes only with what you need.
Our specialists can explain the benefits of the processing, power supply, and other parts. Picking every part of your computer, you can also count on high-quality parts that are easy to upgrade.
A Personal, Expert Relationship
Another selling point for big-box stores is the warranty. This is one more way they’re making money off the sale of your computer. But keep in mind that most of these stores aren’t going to fix your computer on-site. You explain your problem to a retail employee – again, maybe someone knowledgeable about computers (fingers crossed). Then you wait as the computer gets sent into a central repair base, where someone you haven’t spoken with is working on your computer. Then you wait for the computer to come back, hopefully fixed. Something that would take our experts 30 minutes to fix has you waiting a week. That’s a big deal if you depend on that computer on a daily basis.
When you buy from computer specialists, you’re working with a qualified computer technician. You’re building a relationship with someone who knows you and your computer, and you’ll always know where your computer is during the repair process. Additionally, since all parts are hand-picked, you might enjoy individual part warranties.
Building your own computer in the past was expensive, but today there are many more high-quality parts available. Your computer customizer can offer you affordable, reliable cases, RAM, hard drives, fans, GPUs, CPUs, and cooling, and they can help you weigh the benefits of each.
Whether you’re looking for an entry-level or high-end gaming machine, we can customize the best computer for you.
Why settle for a standard, pre-built option made to appeal to the largest number of people? Contact our experts today to start putting together your purpose-built, personalized gaming PC. Call (651) 456-8655 or visit our contact page HERE.

What You Need to Know About Browser Extension Risks – 12/6/2022
With “Googling it” now a common expression, it’s safe to say you do a lot online. To do it all you’re using a Web browser (such as Chrome, Edge, Firefox, etc.). To do it all more efficiently or effectively, you could be using browser extensions, but this article is going to warn you against doing so.
To clarify, browser extensions are code add-ons that you connect to your browser. You can use them to personalize your surfing experience, and they accomplish many different things, including:
saving time (e.g. Scribe, Evernote, StayFocusd);
checking your grammar (e.g. Grammarly);
managing your passwords (e.g. Keeper, LastPass);
securing your online activity (e.g. DuckDuckGo, Ghostery)
Even though we’ve just said they can help secure your online activity and manage your passwords, the problem is that they are also risky.
Consider the fact that we said this represents added code. Now, how much coding do you know? Most will say “not a lot.” That means you’re blindly trusting that browser extension.
If you download a malicious one, that code can wreak havoc. Suddenly, your default search engine gets changed, or you get redirected to a start page with malware on it. You might face an onslaught of pop-ups or ads. They can also track your browsing history without you knowing it.
That’s just the beginning
Many browsers today want to keep you safe from malevolent extensions. They’ll have permissions in place before allowing access. Yet you still end up giving that extension a lot of access. For example, an extension modifying google.com needs access to all your Google activity. That means your Gmail, too.
Browser extensions access everything you’re doing online. So, a malicious extension could also function as a keylogger capturing passwords or credit card details.
A browser extension can also be sold to or hijacked by a bad actor. Then, it’s easy enough for them to push out an update that turns your trusted extension into malware.
What to do about this issue
Does this mean you should do without browser extensions? There are even browser extensions out there to block other browser extensions, but abstinence from extensions is not your only solution.
Instead, we’d recommend reviewing the safety and credibility of that extension. This means you should:
Check to see who published the extension.
Look at the reviews. A high number of positive reviews is a good sign. Thousands of people are unlikely to give five stars to a malicious extension.
Pay attention to the permissions required. If an extension claims to modify only one website, check that it accesses that site only.
Protect yourself with a good antivirus solution.
Keep your antivirus solution and other software updated.
It’s also easier to stay safe by limiting the number of installed extensions you use. If you have browser extensions that you aren’t using, uninstall them. This can cut your exposure to potential threats.
