Watch Out for Ransomware Pretending to Be a Windows Update

Imagine you’re working away on your PC and see a Windows update prompt. Instead of ignoring it, you take action. After all, you want to keep your device safe. But when you install what you think is a legitimate update, you’re infected with ransomware.

That’s the nightmare caused by an emerging cybersecurity threat.

Cybercriminals are constantly devising new ways to infiltrate systems. They encrypt valuable data, leaving victims with difficult choices. Once ransomware infects your system, your PC is pretty useless. You either have to pay a ransom or get someone to remove the malware. As well as install a backup (if you have one!).

One such variant that has emerged recently is the “Big Head” ransomware. It adds a new layer of deception by disguising itself as a Windows update. In this article, we’ll explore the ins and outs of Big Head ransomware. Including its deceptive tactics. We well as how you can protect yourself from falling victim to such attacks.

The Big Head Ransomware Deception

Ransomware attacks have long been infamous for their ability to encrypt files. This renders them inaccessible to the victim until a ransom is paid to the attacker. In the case of Big Head ransomware, the attackers have taken their tactics to the next level. The attack masquerades as a Windows update.

Big Head ransomware presents victims with a convincing and fake Windows update alert. Attackers design this fake alert to trick users. They think that their computer is undergoing a legitimate Windows update. The message may appear in a pop-up window or as a notification.

The deception goes even further. The ransomware uses a forged Microsoft digital signature. This makes the fake update appear more authentic. This adds an extra layer of credibility to the malicious message. And makes it even more challenging for users to discern its true nature.

The attack fools the victim into thinking it’s a legitimate Windows update. They then unknowingly download and execute the ransomware onto their system. From there, the ransomware proceeds to encrypt the victim’s files. Victims see a message demanding a ransom payment in exchange for the decryption key.

By 2031, it’s expected a ransomware attack will occur every 2 seconds.

Protect Yourself from Big Head Ransomware & Similar Threats

Cyber threats are becoming more sophisticated. It’s not just the good guys exploring the uses of ChatGPT. It’s crucial to take proactive steps to protect your data and systems. Here are some strategies to safeguard yourself from ransomware attacks like Big Head.

Keep Software and Systems Updated

This one is tricky. Because updating your computer is a best practice for security. Yet, Big Head ransomware leverages the appearance of Windows updates.

One way to be sure you’re installing a real update is to automate. Automate your Windows updates through your device or an IT provider (like us). This increases the chances of spotting a fake that pops up unexpectedly.

Verify the Authenticity of Update

Before installing any software update, verify its authenticity. Genuine Windows updates will come directly from Microsoft’s official website. Or through your IT service provider or Windows Update settings. Be cautious of unsolicited update notifications. Especially those received via email or from unfamiliar sources.

Verify the Authenticity of Update

Before installing any software update, verify its authenticity. Genuine Windows updates will come directly from Microsoft’s official website. Or through your IT service provider or Windows Update settings. Be cautious of unsolicited update notifications. Especially those received via email or from unfamiliar sources.

Backup Your Data

Regularly back up your important files. Use an external storage device or a secure cloud backup service. In the event of a ransomware attack, having backup copies is vital. Backups of your data can allow you to restore your files without paying a ransom.

Use Robust Security Software

Install reputable antivirus and anti-malware software on your computer. These programs can help detect and block ransomware threats. This helps prevent them infiltrating your system.

Educate Yourself and Others

Stay informed about the latest ransomware threats and tactics. Educate yourself and your colleagues or family members. Discuss the dangers of clicking on suspicious links. As well as downloading attachments from unknown sources.

Use Email Security Measures

Ransomware often spreads through phishing emails. Put in place robust email security measures. Be cautious about opening email attachments or clicking on links. Watch out for emails from unknown senders.

Enable Firewall and Network Security

Activate your computer’s firewall. Use network security solutions to prevent unauthorized access to your network and devices.

Disable Auto-Run Features

Configure your computer to disable auto-run functionality for external drives. This can help prevent ransomware from spreading through infected USB drives.

Be Wary of Pop-Up Alerts

Exercise caution when encountering pop-up alerts. Especially those that ask you to download or install software. Verify the legitimacy of such alerts before taking any action.

Keep an Eye on Your System

Keep an eye on your computer’s performance and any unusual activity. If you notice anything suspicious, investigate immediately. Suspicious PC activity can be:

  • Unexpected system slowdowns
  • File changes
  • Missing files or folders
  • Your PC’s processor “whirring” when you’re not doing anything

Have a Response Plan

In the unfortunate event of a ransomware attack, have a response plan in place. Know how to disconnect from the network. Report the incident to your IT department or a cybersecurity professional. Avoid paying the ransom if possible.

Need a Cybersecurity Audit?

Don’t leave unknown threats lurking in your system. A cybersecurity audit can shed light on your system vulnerabilities. It’s an important proactive measure to ensure network security.

Risk of NOT updating your hardware

When is the time to upgrade?

I will start this post, by knowing we all want to have our cake and eat it, including the cherry on the top! And whilst this might make us sick, if we do the same with the computer hardware in our business, it may even cost us our businesses.

All hardware has a lifespan, this is measured by something called ‘Mean Time Between Failures (MTBF)’ This is the time that any given hardware component may fail at. And this has improved over the years, but even so if you have your business running on a server do you want to risk losing this?

So how long is sensible

When we scope a server, we suggest this is replaced every 5 years, this is based on the MTBF above, but also we scope the growth of the data your business will generate in the 5 years. This will also make sure that your server operating system remains within the support phase by the vendor. We recommend this is never pushed out, because if the server does die, you will be facing a bigger bill to get it back up and working properly and that is if you have a full back up. It is likely that you won’t have access to this for several days!

So just how much would you lose over those couple of days, £5,000, £10,000 more? Is it worth the risk?

Desktops & Laptops

You might have more lee-way with these, if a single computer goes down at least others can work, so the loss might not be as bad. Here at Limbtec the tec’s laptops are looked as disposalable, they are used on site, and you never know when something weird may happen, that was something we decided on many years ago, this may not be for you, but it does suit how we use them.

And that is the important part, is looking at how you will use them, and how long you expect them to last

The business part of this

Your accountant will want to write all this down over 3 years, as mentioned above our laptops issued to tec’s are treated a disposable, so they aren’t written down over any period of time, they are just an expense. our desktops, and other network equipment will be over 3 years, our server are also over 3 years, but potentionally you could say 5 years, specially if you purchase them on a lease!

Then you have compliance

Then you have complaince, and by this in the UK this is mainly GDPR, which states all software needs to be supported this isn’t just the operating system, but also the firmware and any software running on the server.

Handy Checklist for Handling Technology Safely During a Home or Office Move

Handy Checklist for Handling Technology Safely During a Home or Office Move

Moving can be a chaotic and stressful time. Especially when it comes to handling your valuable technology. Whether you’re relocating your home or office, it’s essential to take extra care. Both with fragile items and when packing and moving your devices and other tech items. 

To help you navigate this process smoothly, we’ve put together a handy checklist. Use this to help ensure your technology remains safe and sound during the move.

Back Up Everything

Before you start disassembling your technology, make sure to back up all your data. Create copies of important files, documents, photos, and any other irreplaceable information. You can either use an external hard drive, cloud storage, or both. By doing this, you’ll have peace of mind knowing you’ve protected your data. Should something unfortunate happen during the move, your files will be intact.

Organise and Label Cables

We all know the struggle of untangling a mess of cables. This is true especially when you’re eager to set up your devices in the new place. To avoid this headache, take the time to organise and label your cables before packing.

Use cable ties or twist ties to keep them neatly bundled. Attach labels to identify which cable belongs to which device. Trust us; this simple step will save you a lot of time and frustration later on.

Pack Devices Carefully

When packing your devices, opt for their original boxes whenever possible. If you have the storage space, this is why you don’t want to toss those out. The original packaging is designed to provide the best protection during shipping. There are usually specific compartments to secure each component.

If you don’t have the original boxes, use sturdy cardboard boxes. Wrap each device in bubble wrap or anti-static foam to prevent any damage. Fill any empty spaces in the boxes with packing peanuts or crumpled paper to ensure a snug fit.

Remove Ink Cartridges and Batteries

It might seem easier to just load up your printers “as is” to move them. But that’s not a good idea. For printers and devices that use ink, it’s crucial to remove those cartridges. Do this before packing the devices. Ink cartridges can leak or dry out during transit. This can cause a mess or render them useless.

Also, remove batteries from devices such as laptops, cameras, or remote controls. This precaution prevents accidental power-on and potential damage during the move. Pack the cartridges and batteries separately in sealed bags and label them.

Take Photos of Cable Connections

Before unplugging cables from your devices, snap a quick photo of the connections. This visual reference will be very helpful when it’s time to set up everything at your new location. You won’t have to worry about remembering which cable goes where. And won’t need to spend hours trying to figure it out. Simply refer to the photos, and you’ll be back up and running in no time!

Pack Your Wi-Fi Equipment Separately

Reconnecting to the internet is usually one of the first things done for both home and office moves. To make it easier, pack all your Wi-Fi network equipment separately from other items.

This includes your modem, router, ethernet cables, and other network connectors. Clearly label the box “Wi-Fi Equipment” so you’ll know right where to go first to get online.

Secure Fragile Screens

Are you moving devices with delicate screens, such as TVs or monitors? Then take extra precautions to protect them from scratches and cracks. 

Place a soft cloth or microfiber cloth over the screen. Secure it with elastic bands or tape. This barrier will shield the screen from any accidental contact during transit. Additionally, make sure to pack these items in a vertical position to reduce the risk of damage.

Inform the Movers about Fragile Items

When enlisting professional movers, be sure to be clear about your technology. Inform them about the fragile nature of your devices and other tech items. Clearly label the boxes containing your valuable devices as “fragile.” Provide any necessary instructions to handle them with care. By communicating your concerns upfront, you reduce the chances of accidents while moving.

Test Everything After the Move

If you’ve moved offices, you don’t want to find out about problems on a busy Monday morning. Once you’ve moved your technology and reconnected cables, turn your devices on. Test them to ensure they work as usual and weren’t damaged. 

Something may not look damaged on the outside. But that doesn’t mean that there isn’t internal damage. You want to know this upfront so you can call in an IT service professional to help.

Need Help with a Safe Technology Move?

Limbtec know that moving can be a hectic and challenging process, especially when moving office tech. But with the right approach, you can ensure the safety of your devices from point A to point B.

Do You Still Believe in These Common Tech Myths?

Common Tech Myths

In today’s digital age, technology plays a significant role in our lives. But along with the rapid advancements and innovations, several myths have persisted. 

Is it okay to leave your smartphone charging overnight? Do Macs get viruses? And what about those 5G towers? What’s going on with those?

Common tech myths can often lead to misunderstandings. They can even hinder your ability to fully use various tools and devices. In this blog post, we will debunk some of the most common tech myths that continue to circulate. We’ll also explore the truth behind them.

Myth 1: Leaving your device plugged in overnight damages the battery

First is one of the most persistent tech myths. Leaving your device plugged in overnight will harm the battery life. But this myth is largely outdated.

Modern smartphones, laptops, and other devices have advanced battery management systems. These systems prevent overcharging.

Once your device reaches its maximum charge capacity, it automatically stops charging. This is true even if it remains connected to the power source. In fact, it is often recommended to keep your device plugged in overnight to ensure a full charge by morning.

So, feel free to charge your gadgets overnight without worrying about battery damage.

Myth 2: Incognito mode ensures complete anonymity.

Many users believe that using incognito mode in web browsers guarantees complete anonymity. They feel completely secure while surfing the internet using this mode. But this is not entirely accurate. While incognito mode does provide some privacy benefits, they’re limited.

For example, it mainly prevents your device from saving the following items:

  • Browsing history
  • Cookies
  • Temporary files

However, it does not hide your activities from your internet service provider (ISP). Nor from the websites you visit. ISPs and websites can still track your IP address. They can also still watch your online behavior and collect data.

Do you truly want to remain anonymous online? Then consider using a virtual private network (VPN). Or other specialized tools that provide enhanced privacy protection.

Myth 3: Macs are immune to viruses.

Another prevalent myth is that Mac computers are impervious to viruses and malware. It is true that Macs have historically been less prone to such threats compared to Windows PCs. This does not make them immune. 

Some people that tout this myth point to malware statistics. For example, in 2022, 54% of all malware infections happened in Windows systems. Just 6.2% of them happened in macOS.

But you also need to factor in operating system (OS) market share. As of January 2023, Windows had about 74% of the desktop OS share. Mac’s OS had just 15%.

When you consider this, it turns out the systems aren’t that different when it comes to virus and malware risk. The infection rate per user on Macs is 0.075. This is slightly higher than on Windows, at 0.074. So, both systems have a pretty even risk of infection. This is the case even though Macs have a significantly lower infection count.

As the popularity of Macs has grown, so has the interest of hackers in targeting these devices. Malicious software specifically designed for Macs does exist. Users should take proper precautions, no matter the operating system in use.

Limbtec have always stated the need to install reliable antivirus software. As well as keeping the operating system and applications up to date. Exercise caution when downloading files or clicking on suspicious links. Being aware of potential security risks and practicing safe browsing habits is crucial. This is true for Mac users, just as it is for any other platform.

Myth 4: More megapixels mean better image quality.

When it comes to smartphone cameras, savvy marketing sometimes leads to myths. Many people believe that more megapixels equal better image quality. This is a common misconception.

Megapixels are an essential factor in determining the resolution of an image. But they are not the sole indicator of image quality. Other factors play a significant role. Such as:

  • The size of individual pixels
  • Lens quality
  • Image processing algorithms
  • Low-light performance

A camera with a higher megapixel count may produce larger images. But it does not guarantee superior clarity, color accuracy, or dynamic range.

Manufacturers often strike a balance between pixel count and other image processing technologies. They do this to achieve optimal results. When choosing a smartphone or any camera, consider the complete camera system.  Don’t only focus on the megapixel count.

Separate Fact from Fiction

In a world where technology is an integral part of our lives, you must separate fact from fiction. Debunking common tech myths can empower you to make informed decisions. It can also maximize the potential of your digital experiences. An understanding of the truth behind these myths helps you use technology more effectively. It can also help you better protect your privacy.

Is your business data at risk? Don’t take chances with old tech

Don't gamble on your old tech

When you replace old computers or external drives, do you delete data and then just… get rid of them?

You could be putting your sensitive data at risk.

A new study by a data recovery specialist shows that millions of deleted files can be recovered from improperly wiped hard drives that are sold online.

It’s not just buyers who can access your old files. Cyber criminals often buy used hard drives and attempt to recover data from them. This could include anything from confidential business information to client details.

It’s easy to forget about old data when you’re excited about shiny new technology. However, it’s important to consider what’s on that old drive before selling it or disposing of it.

Even if the drive is encrypted, it’s still possible for data to be recovered. And if the drive is damaged, there’s a chance that some of the data is still salvageable. It’s better to be safe than sorry when it comes to sensitive information.

Think about it this way: Would you leave important documents lying around for anyone to see? Of course not! Your digital information deserves the same level of protection.

So what can you do to protect yourself?

Don’t let your old hard drives become a liability. Take the time to have them properly wiped or destroyed before disposal. If you’re upgrading hardware, consider hiring a professional to handle the data transfer and ensure that your old devices are wiped clean.

This isn’t just about protecting yourself. It’s about protecting your employees, clients, and anyone else whose personal information you may have stored on that old drive.

It’s a small investment to make for the peace of mind that comes with knowing your data is safe from prying eyes.

Don’t take chances with your data – take action to protect it:

  • Properly wipe or destroy old hard drives
  • Bring in a professional for your hardware upgrades
  • Upgrade your overall security practices

3 essential security tools for every business

3 essential security tools for every business

Your data is one of your most valuable business assets. Keeping it safe should be one of your main priorities. So if you don’t have much security in place, there’s a minimum standard you should be implementing, right now.

There are dozens of security solutions available that all perform different tasks – from preventing criminals gaining access, to recognising attacks in progress, and then limiting the damage that can be done. There’s no one-size-fits-all as every business has different priorities and different types of data to protect.

Here are three essentials that every business should put in place as a basic level of protection.

  1. A firewall

A firewall monitors the internet traffic coming into and leaving your IT network. It acts as a wall between your network and the outside world. It’s your first line of defence against an intruder breaking in to your network.

  •  A password manager for everyone in the business.

A password manager stores all your credentials securely, and can also generate nearly impossible-to-guess passwords for all your accounts and applications.

That’s useful against brute force attacks, where cyber criminals essentially try to force their way into your system by guessing the password. It also stops you writing down your passwords somewhere ‘safe’!

  • A VPN (Virtual Private Network)

A VPN is important for any remote or hybrid workers in your business.

It means your employees can access your network from wherever they’re working, without worrying that their online activity is being watched by a criminal.

VPNs make your browsing completely private, hiding your device and location details, and anything you download. If you or your employees regularly use public Wi-Fi – especially to access your network – a VPN is essential.

These are our absolute minimum recommendations.

The strongest security uses additional tools like Multi-Factor Authentication to prove the identity of all users, and antivirus software to deal with any intrusions.

These work together to create a multi-layered security shield to defend against threats on many fronts.

But it’s important you create a security plan that’s right for your specific business. It’s a good idea to seek some professional help.

Not everyone’s as excited about IT security as we are! But we definitely have a passion for it.

When did you last have a health check?

When did you last have a health check?

Did you start a January Health kick? How is it going?

January is that time of year when a lot of us take our health seriously, well for a month or so! It is a good thing to look after yourself, and do something about it.

Your doctor would probably like to see you once a year for a health check, just to find any small problems and stop them from progressing.

It is the same principle with your technology.

So why not book in for an IT check-up, to make sure everything is in great shape for the coming months.

After all we do this for Ourselves, or our car, and it’s a good plan to do the same with your workplace tech. After all it might be working really hard in the year ahead.

What would we do

We will help pick up any minor-but-urgent fixes, that could help prevent a disastrous breakdown in a few months time. (we have just seen this where we identified an issue with a server, which went on the break, and was unable to be repaired just 4 months later)

If there are bigger, but no-urgent jobs that you can safely leave for another day, we will tell you that too.

And if you get a clean bill of health, you can carry on with confidence for the coming months.

It may also be a great time to think about new technology and prioritise your IT projects. We can look at what you need to do with your systems as your business grows.

Working from home, is it good for your business?

Working from home. Or remote working, as it’s now called.

It’s the big thing in business, isn’t it? And some people love it.

They’re happier working where they want, and when they want. And that makes them more productive and less likely to leave.

But have you stopped to consider the downside to remote working? The negative elements for your business and your people?

While many employees are happy to work from home using video calls and collaborative software to stay connected, there’s a small percentage who find the whole experience isolating.

And when that happens, it can quickly lead to a drop in motivation and happiness. It can even change the culture within your business.

In turn, this can lead to performance issues which may be trickier to spot.

At the other extreme, some employees will become more susceptible to burnout as they struggle to draw a line between work and personal time. That change in environment can be so important for some.

And while you want your team to be happy and fulfilled in their roles, there are also some practical considerations you need to make for your business.

Practical Considerations

Such as the cost of remote working. Does everyone have the right tools for the job – laptops, phones, office equipment? Maybe even a desk and chair, or an internet upgrade?

Do you need to spend twice – giving them an at home setup and investing in hot desks in the office?

Most importantly, you must put in place full cyber security protection wherever someone is working.

Here’s how we can help you stay safe and potentially save money.

Would you like us to audit your current setup and suggest some options? This is what we do every day. Just get in touch.

The Global Chip Shortage and your business.

The global chip shortage has been with us for the past couple of years, the tech world has been struggling with a huge shortage of chips.

But it’s not just tech businesses that are feeling the impact.

Pretty much everything we use every day has at least one chip in it. Laptops and desktops, sure. But also household appliances, even our cars. It’s hard to find an electric device without at least one chip.

This global chip shortage has the potential to disrupt our modern lives.

Did you know, it’s been ongoing since 2020 (ah, that year really was a gift, wasn’t it)?

It started during the pandemic as production fell while demand went up.

Other events since have made it worse, including extreme weather, the Ukraine war and a factory fire.

The need to increase chip production

We’re told that increasing chip production isn’t easy. It can take years to build a new factory because of the unique production demands.

Of course, all of this is someone else’s problem. Let’s make it real to you – what does this actually mean for your business?

Essentially it means you need to plan ahead more.

Some of the technology you need to run your business may be in short supply.

As an example, getting large numbers of the same laptop might be difficult, compared to getting just 2 or 3.

And some of the essential devices you rarely think about as they’re in the background, such as network switches, are currently much harder to get.

As you push your business towards increased growth it means planning ahead more than ever before.

Industry experts expect the shortage to last into next year… and it could be even longer.

Would you like to run your growth plans by us, so we can advise what might need to be ordered, when? Get in touch.
