What is Zero-Click Malware?

How Do You Fight It?  

Zero Click Malware

In today’s digital landscape, cybersecurity threats continue to evolve. They pose significant risks to individuals and organizations alike. One such threat gaining prominence is zero-click malware. This insidious form of malware requires no user interaction. It can silently compromise devices and networks.

One example of this type of attack happened due to a missed call. That’s right, the victim didn’t even have to answer. This infamous WhatsApp breach occurred in 2019, and a zero-day exploit enabled it. The missed call triggered a spyware injection into a resource in the device’s software.

A more recent threat is a new zero-click hack targeting iOS users. This attack initiates when the user receives a message via iMessage. They don’t even need to interact with the message of the malicious code to execute. That code allows a total device takeover.

Below, we will delve into what zero-click malware is. We’ll also explore effective strategies to combat this growing menace.

Understanding Zero-Click Malware

Zero-click malware refers to malicious software that can do a specific thing. It can exploit vulnerabilities in an app or system with no interaction from the user. It is unlike traditional malware that requires users to click on a link or download a file.

Zero-click malware operates in the background, often unbeknownst to the victim. It can infiltrate devices through various attack vectors. These include malicious websites, compromised networks, or even legitimate applications with security loopholes.

The Dangers of Zero-Click Malware

Zero-click malware presents a significant threat. This is due to its stealthy nature and ability to bypass security measures. Once it infects a device, it can execute a range of malicious activities.

These include:

  • Data theft
  • Remote control
  • Cryptocurrency mining
  • Spyware
  • Ransomware
  • Turning devices into botnets for launching attacks

This type of malware can affect individuals, businesses, and even critical infrastructure. Attacks can lead to financial losses, data breaches, and reputational damage.

Fighting Zero-Click Malware

To protect against zero-click malware, it is crucial to adopt two things. A proactive and multi-layered approach to cybersecurity. Here are some essential strategies to consider:

Keep Software Up to Date

Regularly update software, including operating systems, applications, and security patches. This is vital in preventing zero-click malware attacks. Software updates often contain bug fixes and security enhancements. These things address vulnerabilities targeted by malware developers. Enabling automatic updates can streamline this process and ensure devices remain protected.

Put in Place Robust Endpoint Protection

Deploying comprehensive endpoint protection solutions can help detect and block zero-click malware. Use advanced antivirus software, firewalls, and intrusion detection systems. They establish many layers of defense. These solutions should be regularly updated. This ensures the latest threat intelligence to stay ahead of emerging malware variants.

Use Network Segmentation

Segment networks into distinct zones. Base these on user roles, device types, or sensitivity levels. This adds an extra layer of protection against zero-click malware. Isolate critical systems and install strict access controls to limit the damage. These help to mitigate lateral movement of malware and its potential harm.

Educate Users

Human error remains a significant factor in successful malware attacks. A full 88% of data breaches are the result of human error.

Educate users about the risks of zero-click malware and promote good cybersecurity practices. This is crucial. Encourage strong password management. As well as caution when opening email attachments or clicking on unfamiliar links. Support regular training on identifying phishing attempts.

Use Behavioral Analytics and AI

Leverage advanced technologies like behavioral analytics and artificial intelligence. These can help identify anomalous activities that may indicate zero-click malware. These solutions detect patterns, anomalies, and suspicious behavior. This allows for early detection and proactive mitigation.

Conduct Regular Vulnerability Assessments

Perform routine vulnerability assessments and penetration testing. This can help identify weaknesses in systems and applications. Weaknesses that enable an exploit by zero-click malware. Address these vulnerabilities promptly through patching or other remediation measures. These actions can significantly reduce the attack surface.

Uninstall Unneeded Applications

The more applications on a device, the more vulnerabilities it has. Many users download apps then rarely use them. Yet they remain on their device, vulnerable to an attack. They are also more likely to lack updates.

Have employees or your IT team remove unneeded apps on all company devices. This will reduce the potential vulnerabilities to your network.

Only Download Apps from Official App Stores

Be careful where you download apps. You should only download from official app stores. Even when you do, check the reviews and comments. Malicious apps can sometimes slip through the security controls before they’re discovered.

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.

Browse with confidence: Microsoft Edge’s security boost

Edge update - Browse with confidence

Browsing the web can be risky. It only takes one click on one bad link to put your business’s data at risk.

With cyber criminals constantly targeting businesses using automated tools, it’s important to stay one step ahead with your online security.

That’s why we’re excited that Microsoft is working on a major security update for its Edge browser, which will bring enhanced security to everyone using it.

It’s adding new security features and beefing up existing ones.

Maybe you’ve already seen features such as Password Monitor. This alerts you if any of your saved passwords have been compromised in a data breach, prompting you to change them immediately.

There’s also SmartScreen technology, which will help safeguard you from phishing scams and malware.

This checks websites against a list of known malicious sites, as well as analysing URLs for any suspicious patterns or characteristics. If it detects something that’s not right, you’ll be warned before you proceed to the site.

Why should you care about all these security updates?

It comes down to this: Using a less secure browser could leave you vulnerable to all sorts of online threats. Cyber criminals are constantly coming up with new ways to exploit weaknesses in software, so it’s important to stay up-to-date with the latest security measures.

Plus, let’s face it – no one wants to deal with the aftermath of a cyber attack. Whether it’s dealing with financial losses, identity theft, or just the hassle of cleaning up the mess, the consequences of a breach can be far-reaching.

By using a secure browser like Edge, you can reduce your risk of falling victim to such attacks.

Of course, we know that not everyone is an expert on cyber security. That’s why Microsoft is making it easy to stay safe without needing a degree in computer science.

The new security features are built-in and easy to use so you don’t have to worry about configuring anything yourself. You can browse the web with peace of mind.

If you’re not already using Edge, give it a go. And if you need help getting your 365 suite optimised for your business, get in touch.

What is AI?

The whole world is suddenly talking about Artificial Intelligence.

From Alexa in your kitchen, to Siri on your phone, AI is already all around us, but new names like ChatGPT, Dall-E, Jasper and more feel like they’ve blown up the internet.

These new concepts take things WAY further, helping us to write articles, search the web with natural conversation, generate images, create code, and introduce new ways to make our daily lives even easier.

But emerging technology nearly always launches in a blizzard of geek-speak before it settles into everyday life. Early PC users might remember the ‘DOS prompt’. And when did you ever have to ‘defrag’ your phone?

Experts believe that these new AI tools will become the building blocks of a whole new world of tech, redefining the way we interact with computers and machines.

So let’s help you decode some of the terms you’ll hear this year.

Chatbot Starting with the basics, a chatbot is an app that mimics human-to-human contact. Just type or speak normally, and the chatbot will respond the same way. ChatGPT is a chatbot. If you haven’t tried it out yet, give it a go.

Deep learning This is the technique that’s used to imitate the human brain, by learning from data. Current search tools and systems use pre-programmed algorithms to respond to requests. AI tools are trained on concepts and conversations in the real-world, and learn as they go to provide human-like responses.

Machine intelligence The umbrella term for machine learning, deep learning, and conventional algorithms. “Will machine intelligence surpass human ingenuity?”

Natural Language Understanding (NLU) helps machines understand the meaning of what we say, even if we make grammatical errors or speak with different regional accents.

Weak AI is the most common form of AI in use right now. Weak AI is non-sentient and typically focuses on a single or small range of activities – for instance writing, or repurposing video content. Strong AI, on the other hand has the goal of producing systems that are as intelligent and skilled as the human mind. Just not yet.

This is just the tip of the iceberg, but trust us – you’re going to be hearing a lot more about AI in the months and years to come.

If you’d like more help to understand how AI might form part of your business, just get in touch.

Phishing Emails are getting better thanks to AI

AI is making phishing scams more dangerous

AI chatbots have taken the world by storm in recent months. We’ve been having fun asking ChatGPT questions, trying to find out how much of our jobs it can do, and even getting it to tell us jokes.

But while lots of people have been having fun, cyber criminals have been powering ahead and finding ways to use AI for more sinister purposes.

They’ve worked out that AI can make their phishing scams harder to detect – and that makes them more successful.

Our advice has always been to be cautious with emails. Read them carefully. Look out for spelling mistakes and grammatical errors. Make sure it’s the real deal before clicking any links.

And that’s still excellent advice.

But ironically, the phishing emails generated by a chatbot feel more human than ever before – which puts you and your people at greater risk of falling for a scam. So we all need to be even more careful.

Crooks are using AI to generate unique variations of the same phishing lure. They’re using it to eradicate spelling and grammar mistakes, and even to create entire email threads to make the scam more plausible.

Security tools to detect messages written by AI are in development, but they’re still a way off.

That means you need to be extra cautious when opening emails – especially ones you’re not expecting. Always check the address the message is sent from, and double-check with the sender (not by replying to the email!) if you have even the smallest doubt.

Malicious browser extension are you using them?

There are hundreds of thousands of browser extensions designed to help us to save time, be more productive, and personalise our online experience.

And while the majority of them do what they’re supposed to, some are not designed to help you at all…

If you’re unfortunate enough to download a malicious browser extension without realising, it could harm your productivity and even flood your work with unwanted advertising.

This is known as adware. It’s a form of malware (malicious software) that’s designed to bombard you with unwanted adverts.

It can also change your search engine and send you to affiliate pages when you’re making purchases. These activities generate revenue for the extension’s creators.

In a recent report from a cyber security company, it revealed more than 4 million of its customers have been attacked by adware hiding in browser extensions over the last couple of years.

And often people didn’t realise they were under attack.

There’s a darker scenario where these malicious extensions are hiding actual malware which can infect your computer.

This can lead to sensitive data such as your logins or even payment details being stolen. And of course malware can spread across an entire network.

To keep your business and its data safe from the risk of malicious browser extensions, it’s important you only ever download them from reliable and trusted sources.

What to do

Read reviews and look at ratings. If a browser seems too good to be true it probably is.

As the business owner, you might also look into controlling which extensions can be installed by your team.

We can help with this, as well as looking at up-to-date software protection and (fun) security training for your team.

Are you under pressure to take action.

Phishing scams are one of the biggest security threats to your business right now. As we all get used to these emails the scammers are upping the pressure to take urgent action.

A massive 83% of organisations said they suffered successful attacks last year. And with just under a third of phishing emails being opened, the chances that someone in your business will be fooled are high.

But to make matters more difficult, cyber criminals have borrowed a technique from ransomware groups that is designed to panic people into taking action and giving away their login details.

This phishing attack begins like most others, then the pressure to take urgent action.

You get an email alerting you to potentially suspicious activity on your account. It might say someone is trying to login from a different location or device and the attempt has been blocked.

You’re then asked to click a link to verify your email address and password.

That’s worrying enough, right?

But what makes this phishing attack even more dangerous, is the countdown timer that appears on screen.

Typically, it’s set at one hour, and you’re asked to confirm your details before the countdown ends, otherwise your account will be deleted.

Yes, deleted! That catches a lot of people’s attention.

This is a powerful manipulation tactic designed to scare people into taking immediate action – and think later.

In reality, if that countdown hits zero nothing will happen. But watching the seconds count down can give you a sense of urgency that makes you forget to check whether an email is the real deal or not.

The page you’re entering your details on is fake. Criminals will steal your details and login to your real account. That’s a major problem you don’t ever want your business to face.

You’ll be at risk of data theft, financial loss, or malware, as well as potentially putting other accounts at risk (if you’ve reused your password).

Your login details may even be sold on the dark web, giving other cyber criminals the opportunity to break into your account.

Here are some basic phishing protections for you and your team.

Look at the email address the email was sent from. Make sure the spelling and grammar are both correct, and hover over links to see what website address they are trying to send you to.

If you think you’ve fallen for this kind of scam, it’s important you change your login details immediately. Don’t click a link in an email – type in the website address in your browser.

We’d also recommend using a password manager. This is software that creates long and strong random passwords that are impossible to guess for every account you have.

It will store these passwords for you. And autofill login boxes to save you time (yes, password managers detect when they’re being asked to fill in details on a different page, such as a fake phishing page).

Share this article with your whole team right now. And if anyone ever clicks a link they’re not sure about, ask us how to keep your business safe.

Are your Apps spying on you?

Are your apps spying on you. It’s no secret that some applications are a little too interested in us and what we’re doing.

We’ve all had this experience. You might be talking to a friend about a new product that you’d like to try. Or perhaps you’ve discussed somewhere you’d like to visit.

Then the next time you go online you see adverts for the exact things you were talking about.

It’s more than a coincidence, surely???

Until recently, we haven’t had a lot of control over what information our apps are gathering about us.

Android and iOS first stepped up to give us more power over our online privacy. We were given the ability to control which apps could access our data, and sensitive things like our camera and microphone.

But while it’s easy to think of this only being an issue with phones… laptops have the same problems.

So here’s some great news, to stop your apps spying on you.

Microsoft’s testing a new feature in Windows 11 to put the power back in our hands.

It’s currently testing a new feature – called Privacy Auditing – which allows you to see which applications have been accessing sensitive hardware, like your webcam and microphone.

You’ll also be able to see if your screenshots, messages, and even your contacts and location data have been accessed. And there’s a log of which apps accessed this info, and when.

When launched, the feature will be available in your Privacy & Security menu, under App Permissions.

There you’ll be able to see a full list of what’s been accessed, by which app, and when. It should become your first port of call if you suspect any suspicious activity is taking place on your device.

When the feature is released, it will be a great tool to check periodically to help you avoid malicious activity and to make sure your sensitive data remains in the right hands.

In the meantime, if you’d like someone to look over the data permissions on your business’s devices, get in touch.

Google Chrome is going to block notifications

Google are looking to block disruptive notifications, we explore what they are, and why Google is doing this.

When you’re browsing it can feel like you’re being bombarded with things other people want you to see.

Not only do we have to click on permissions for cookies and tracking, but now a lot of websites ask for our permission to send us notifications.

And while many of these notifications are harmless – news updates, latest recipes, product releases – sometimes they can be outright spam.

It’s distracting, it’s making us less productive at work, and it’s just really annoying.

It’s called ‘notification spam’ and it’s becoming a problem. In fact, Google says it’s one of the top complaint reports from people using its Chrome browser.

So now the tech giant has decided to do more about it disruptive notifications.

Back in October 2020, Google first acted on harmful notifications by exposing websites that misled people into giving permission. It created its own prompts to warn people the website may have malicious intent.

Now, Google intends to take things a step further if it feels the website is ‘abusive’ or ‘disruptive’. It’ll revoke a website’s permission to send notifications, and even block attempts to request permission.

Even if you’ve accidentally allowed a malicious site to send notifications. Chrome will be able to step in and block the alerts.

While it’s not yet clear how Google will define websites as ‘abusive’ or ‘disruptive’, it feels like a good move towards reducing the amount of spam we’re exposed to.

Google has explained that this new feature works to strengthen its ‘Developer Terms of Service’ that pledge not to use the company’s API to send any form of spam. It shouldn’t affect the majority of websites, but instead should go some way to keeping your Chrome notifications spam-free.

Development on Chrome’s notification spam block protection has only just started, so we don’t yet have a release date for the new feature.

As always, get in touch if you would like help to protect yourself.
