SHOCK STAT: A third of business owners don’t trust their staff

27th November 2023
Do you trust your staff with your data.

Do you trust your employees with confidential information?

If you do, you’ll be surprised by this stat…

For a third of small and medium-sized business leaders, the answer is a resounding “no”!

Maybe it’s because Jim from accounting still has his password on a Post-it note under his keyboard? Or perhaps it’s because they’ve been burnt in the past?

Either way, it’s clear that trust isn’t enough when it comes to data security.

We believe the problem isn’t your employees; it’s the lack of good training and security measures.

So, what can you do about it?

Booking training for everyone is an easy first step. It empowers employees with the tools, techniques, and best practices they need to spot potential threats and take appropriate actions.

Think of it this way: well-trained staff pose less of a risk to the overall security of your business’s digital network. They become your first line of defence, helping to improve your company’s security, and significantly reducing the risk of a breach.

Next, there are your security measures. Many companies admit they don’t have sufficient technology or checks to protect confidential information. 

This is where we come in. We can help set up your company’s system so that people can only access the data they’re supposed to.

But our job wouldn’t stop there. We can also ensure that your company has adequate policies relating to information sharing, gaining access to confidential data, and what happens when an employee leaves. By doing this we help you create a more secure working environment for everyone.

Here’s the truth: trust isn’t enough in data security. But with the right training and security measures in place, you can transform your employees from potential security risks into your greatest assets.

Are you ready to move from a place of fear and mistrust to one of empowerment and confidence? Get in touch.

10 Biggest Cybersecurity Mistakes of Small Companies

22nd November 2023

Cybercriminals can launch very sophisticated attacks. But it’s often lax cybersecurity practices that enable most breaches. This is especially true when it comes to small and mid-sized businesses (SMBs).

Cybersecurity measures is often not a priority for small businesses, they tend to be more focused on other areas of the business. Sometimes the business owner thinks there is a low chance of a data breach. Or view cybersecurity as an expense.

But cybersecurity is not only a concern for large corporations. It’s a critical issue for small businesses as well. Small businesses are often seen as attractive targets for cybercriminals. This is due to many perceived vulnerabilities. 

Fifty percent of SMBs have been victims of cyberattacks. More than 60% of them go out of business afterward.

Cybersecurity doesn’t need to be expensive. Most data breaches are the result of human error. But that is actually good news. It means that improving cyber hygiene can reduce the risk of falling victim to an attack.

Are You Making Any of These Cybersecurity Mistakes?

To address the issue, you need to first identify the problem. Often the teams at SMBs are making mistakes they don’t even realise. Below are some of the biggest reasons small businesses fall victim to cyberattacks. Read on to see if any of this sounds familiar around your company.

1. Underestimating the Threat

One of the biggest cybersecurity mistakes of SMBs is underestimating the threat landscape. Many business owners assume that their company is too small to be a target. But this is a dangerous misconception. 

We see that Cybercriminals think small businesses as easy targets. They believe the company lacks the resources or expertise to defend against attacks. It’s essential to understand that no business is too small for cybercriminals to target. Being proactive in cybersecurity is critical.

2. Neglecting Employee Training

When was the last time you trained your employees on cybersecurity? Small businesses often neglect cybersecurity training for their employees. Owners assume that they will naturally be cautious online.

But the human factor is a significant source of security vulnerabilities. Employees may inadvertently click on malicious links or download infected files. Staff cybersecurity training helps them:

  • Recognise phishing attempts
  • Understand the importance of strong passwords
  • Be aware of social engineering tactics used by cybercriminals

3. Using Weak Passwords

Weak passwords are a common security vulnerability in small companies. Many employees use easily guessable passwords. They also reuse the same password for several accounts. This can leave your company’s sensitive information exposed to hackers.

People reuse passwords 64% of the time.

Encourage the use of strong, unique passwords. Consider implementing multi-factor authentication (MFA) wherever possible. This adds an extra layer of security.

Limbtec we use a password manager, and let that take care of choosing the passwords, so we end up with very complex passwords, along with MFA

4. Ignoring Software Updates

Failing to keep software and operating systems up to date is another mistake. Cybercriminals often exploit known vulnerabilities in outdated software to gain access to systems. Small businesses should regularly update their software to patch known security flaws. This includes operating systems, web browsers, and antivirus programs.

This is something we take care of for all our customers.

5. Lacking a Data Backup Plan

Small companies may not have formal data backup and recovery plans. They might mistakenly assume that data loss won’t happen to them. But data loss can occur due to various reasons. This includes cyberattacks, hardware failures, or human errors.

Regularly back up your company’s critical data. Test the backups to ensure they can be successfully restored in case of a data loss incident.

6. No Formal Security Policies

Small businesses often operate without clear policies and procedures. With no clear and enforceable security policies, employees may not know critical information. Such as how to handle sensitive data. Or how to use company devices securely or respond to security incidents. 

Small businesses should establish formal security policies and procedures. As well as communicate them to all employees. These policies should cover things like:

  • Password management
  • Data handling
  • Incident reporting
  • Remote work security
  • And other security topics

7. Ignoring Mobile Security

As more employees use mobile devices for work, mobile security is increasingly important. Small companies often overlook this aspect of cybersecurity.

Put in place mobile device management (MDM) solutions. These enforce security policies on company- and employee-owned devices used for work-related activities.

8. Failing to Regularly Watch Networks

SMBs may not have IT staff to watch their networks for suspicious activities. This can result in delayed detection of security breaches.

Install network monitoring tools. Or consider outsourcing network monitoring services. This can help your business promptly identify and respond to potential threats.

9. No Incident Response Plan

In the face of a cybersecurity incident, SMBs without an incident response plan may panic. They can also respond ineffectively.

Develop a comprehensive incident response plan. One that outlines the steps to take when a security incident occurs. This should include communication plans, isolation procedures, and a clear chain of command.

10. Thinking They Don’t Need Managed IT Services

Cyber threats are continually evolving. New attack techniques emerge regularly. Small businesses often have a hard time keeping up. Yet, they believe they are “too small” to pay for managed IT services.

Managed services come in all package sizes. This includes those designed for SMB budgets. A managed service provider (MSP) can keep your business safe from cyberattacks. As well as save you money at the same time by optimising your IT.

Watch Out for Ransomware Pretending to Be a Windows Update

8th November 2023

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.

May A Force Field Be With You

1st November 2023
Force Field around a laptop

“That won’t happen to me” is something many business owners say when discussing cyber-scams and the need for adequate protections for their business, but these days it’s getting to be a really, really stupid statement that you definitely don’t want your clients, employees and banker to hear.

Generative AI (artificial intelligence) tools are allowing scammers to produce deep fakes to defraud their targets. Earlier this year, Clive Kabatznik, an investor in Florida, called his local Bank of America representative to discuss a big money transfer he was planning to make.

Immediately after this legitimate call, a scammer called the bank back using an AI-generated deepfake voice of “Clive” to convince the banker to transfer the money to another account. Fortunately, the banker was suspicious enough that no money was transferred, but not everyone is as lucky.

According to a report titled The Artificial Imposter by McAfee, a well-established cyber security firm, 77% of AI voice scams were successful in securing money from their target. Even scarier, AI tools can clone a voice from just three seconds of audio.

A UK-based energy firm’s CEO was the victim of a voice scam when he thought he was talking to his boss, the CEO of the parent company based in Germany. The voice on the other end of the line instructed him to send the equivalent of $233,000 to a Hungarian supplier. The voice was so convincing, down to the slight German accent, that the CEO complied without hesitation. By the time they realized what had happened, the money had already been transferred to Mexico and distributed to other locations that weren’t traceable. 

But big businesses aren’t the only ones targeted.

Jennifer DeStefano, a mother of a 15-year-old daughter, recounted during a US Senate hearing her terrifying encounter with an AI scammer who used the voice of her daughter to attempt to convince her that the girl had been kidnapped. Fortunately, her daughter was in her bed sleeping at the time, and Jennifer was able to realize it was a scam. Many others aren’t as lucky as Jennifer and are getting scammed by AI voices of grandchildren, children and other loved ones who “urgently need money.”

This approach is still so new that there’s no comprehensive accounting of how often it’s happening, but the CEO of Pindrop, a security company that monitors audio traffic for many of the largest US banks, said he had seen a jump in its prevalence this year – and in the sophistication of scammers’ voice-fraud attempts. Another large voice-authentication vendor, Nuance, saw its first successful deepfake attack on a financial services client late last year.

With the rapid advancement of AI technology and its wider availability as costs come down, coupled with the broad availability of recordings of people’s voices on TikTok, Facebook, Instagram and YouTube, the perfect conditions have been created for voice-related AI scams.

What do you need to do to protect yourself?

For starters, share this article to make sure your staff is aware of these types of scams. Next, instruct them to ALWAYS check with you via a text message or other means BEFORE transferring money. If you’re not a business owner, you can do the same with your family, using a code word or other means of verifying the caller’s legitimacy.

Also, check the caller ID. If it’s something you don’t recognize, or it’s a blocked number, that’s a BIG red flag that it’s a scam. Even if it sounds like them on the other end of the line, hang up and call their phone direct or the place they’re supposed to be (school, office, etc.).

If the person calling has on-fire urgency and wants money wire-transferred or a Bitcoin payment, that’s another huge red flag. Real emergencies don’t come with highly skeptical payment demands.  

In business, you’ve clawed and climbed your way to the top, dodging all sorts of pitfalls and predators that have tried to make you their meal. Such threats are everywhere, and the higher you climb, the more you’ll find hiding behind every tree, every rock and every step. No matter how small and insignificant you might think you are, you ARE a target for someone, and being casual about cyber security and the threats they pose is an absolute surefire way to be robbed.

If you don’t want this to happen to you, click here to request a free Cyber Security Risk Assessment to see just how protected your organization is against known predators. If you haven’t had an independent third party conduct this audit in the last 6 months, you’re due.

It’s completely free and confidential, without obligation. Voice scams are just the latest in a tsunami of threats aimed at small business owners, with the most susceptible being the ones who never “check the locks” to ensure their current IT company is doing what they should.

That long password isn’t keeping you better protected

30th October 2023
Passwords are important

How secure do you think your passwords are? Do you believe that longer is always better? Well, we have some news for you. It’s time for a serious talk about password security.

New research has revealed a sobering truth – even passwords that are 15 characters long can be compromised. Yes, you read that right. It’s time to face the stark reality… length doesn’t always mean strength.

The eight-character password reigns supreme as the most compromised length of password. But don’t breathe a sigh of relief if yours is a longer one. The 15-character password also makes an appearance in the top ten most compromised lengths.

You might ask, “How could this be?” The answer lies not only in the password length but also in the content of the password and whether you use the same password on multiple sites.

The most compromised eight-character password is none other than “password” itself, while the most compromised 15-character password is “Sym_newhireOEIE”.

Doesn’t exactly feel secure, does it?

It’s not just about individual people. Businesses like yours are at high risk too. An alarming 86% of all cyber attacks start with stolen credentials. That’s nearly nine out of ten attacks. Can you afford to be complacent?

Sure, longer passwords do offer more resistance to brute force cracking. An eight-character password can be cracked in five minutes, while a good 15-character one could take up to 37 million years if it’s not following any obvious pattern (i.e., it’s random and uses many types of character). Impressive, isn’t it?

But remember, this is just one piece of the puzzle. Length alone won’t save you from stolen credentials via phishing attacks.

Use a robust business password manager. Not only will it randomly generate long passwords for you, but it will also remember them and fill in the login box for you.

You should also use two factor authentication, where you generate a code on a separate device to prove it’s you. Even if cyber criminals crack your password, they still won’t be able to access your data.

Are Your Business Tools Ticking Time Bombs For A Cyber-Attack?

30th August 2023
Are Your Business Tools Ticking Time Bombs For A Cyber-Attack?

In June a popular file-sharing software amongst big-name companies likes Shell, Siemens Energy, Sony, several large law firms, a number of US federal agencies such as the Department of Health and more was hacked by Russia-linked cybercrime group Cl0p. Security Magazine reported that, to date, there are 138 known companies impacted by the breach, resulting in the personal information of more than 15 million people being compromised. More are expected to emerge as the investigation continues.

If you’re reading that list of company names thinking, “I’m just a small business compared to these big guys – that won’t happen to me,” we’ve got news for you. Many of these companies have cyber security budgets in the millions, and it still happened to them, not because they were ignoring the importance of cyber security, but because of a piece of software they use to run their business.

Progress Software’s MOVEit, ironically advertised as a tool you can use to “securely share files across the enterprise and globally,” “reduce the risk of data loss” and “assure regulatory compliance,” was exploited by a tactic called a zero-day attack. This occurs when there is a flaw in the application that creates a gap in security and has no available patch or defense because the software maker doesn’t know it exists. Cybercriminals quickly release malware to exploit the vulnerability before the software maker can patch it, essentially giving them “zero days” to respond.

These attacks are dangerous because they are difficult to prevent and can quickly and easily ruin smaller businesses.

Depending on the organization’s motives, the stolen data can be deleted, held for ransom or sold on the dark web. Or, if you are lucky enough to recover your data, you might still end up paying out thousands or more in fines and lawsuits, losing money from downtime and coming out on the other end with a damaged reputation that causes clients to leave anyway. In MOVEit’s case, the cybercrime agency Cl0p has claimed on their website that their motivation is purely financial and has allegedly deleted data obtained from government agencies as they were not the intended targets.

What does this mean for small businesses?

For starters, it underlines the harsh reality that cyber security isn’t just the concern of big businesses and government agencies. In fact, small businesses can be more vulnerable to cyber-attacks, as they often dedicate fewer resources to protection.

It also means that even if your organization is secure, the third-party vendors you work with and the tools you choose to use in your business still pose potential risks. Most of MOVEit’s customers that were affected likely had strong cyber security measures in place. Even though it was no direct fault of their own, at the end of the day, those companies still must go back to their clients, disclose what happened and take the verbal, legal and financial beating that comes with a data breach.

The MOVEit hack serves as a grim reminder of the critical importance of cyber security for businesses of all sizes.In the face of an increasingly sophisticated and fast-moving cyberthreat landscape, businesses cannot afford to ignore these risks. Cyber security must be an ongoing effort, involving regular assessments, updates, monitoring, training and more. As this terrible incident shows, a single vulnerability can lead to a catastrophic breach with severe implications for the business and its customers.

In the digital age, cyber security isn’t just a technical issue – it’s a business imperative.

7 Reasons to Adopt a Defense-in-Depth Cybersecurity Strategy

23rd August 2023
Enhanced CyberSecurity

Cybersecurity threats are becoming increasingly sophisticated and prevalent. In 2022, ransomware attacks jumped by 93%. The introduction of ChatGPT will only increase the potential damage of cyber-attacks.

Protecting sensitive data and systems requires a comprehensive approach. One that goes beyond a single security solution. This is where a defense-in-depth cybersecurity strategy comes into play.

In this article, we will explore the advantages of adopting a defense-in-depth approach. As well as its benefits for safeguarding your network and mitigating cyber risks.

What Does a Defense-in-Depth Approach Mean?

First, let’s define what it means to use a defense-in-depth approach to cybersecurity.  In simple terms, it means having many layers of protection for your technology.

Just like how you might have locks on your doors, security cameras, and an alarm system to protect your home. A defense-in-depth strategy uses different security measures to safeguard your digital assets.

Many layers are better than one when it comes to security. A defense-in-depth strategy combines various defenses. This is to make it harder for cyber attackers to succeed.

These defenses can include things like:

  • Firewalls
  • Antivirus software
  • Strong passwords
  • Encryption
  • Employee training
  • Access management
  • Endpoint security

A defense-in-depth strategy also emphasizes early detection and rapid response. It involves using tools and systems that can quickly detect suspicious activities. This enables you to catch an attacker early. And take action to reduce any damage.

A defense-in-depth cybersecurity strategy provides a strong and resilient defense system. Its several layers of security increase the chances of staying secure. This is especially important in today’s dangerous online world.

Advantages of Adopting a Defense-in-Depth Approach

Enhanced Protection

A defense-in-depth strategy protects your infrastructure in many ways. This makes it harder for attackers to breach your systems. Implementing a combination of security controls creates a robust security posture. Each layer acts as a barrier. If one layer fails, the others remain intact. This minimizes the chances of a successful attack.

Early Detection and Rapid Response

With a defense-in-depth approach, you have many security measures that can detect threats. As well as alert you to these potential dangers.

Some systems used to detect suspicious activities and anomalies in real time are:

  • Intrusion detection systems
  • Network monitoring tools
  • Security incident and event management (SIEM) solutions

This early detection allows you to respond quickly. This minimizes the impact of a potential breach. It also reduces the time an attacker has to access critical assets.

Reduces Single Point of Failure

A defense-in-depth strategy ensures that there is no single point of failure. Such as a single vulnerability that could compromise your entire security infrastructure. Relying solely on one security measure, such as a firewall, could prove catastrophic. Especially if it fails or if attackers find a way to bypass it.

It’s better to diversify your security controls. You create a resilient defense system. One where the failure of one control does not lead to a complete breach.

Protects Against Advanced Threats

Cybercriminals continually evolve their techniques to overcome traditional security measures. A defense-in-depth approach accounts for this reality. It incorporates advanced security technologies. Such as behavior analytics, machine learning, and artificial intelligence. These technologies can identify and block sophisticated threats. This includes zero-day exploits and targeted attacks. They do this by analyzing patterns and detecting anomalies in real time.

Compliance and Regulatory Requirements

Many industries are subject to specific compliance and regulatory requirements. Such as the General Data Protection Regulation (GDPR) or the Health Insurance Portability and Accountability Act (HIPAA). Adopting a defense-in-depth strategy can help you meet these requirements.

By implementing the necessary security controls, you show a proactive approach. It’s proof of your efforts to protect sensitive data.  This can help you avoid legal and financial penalties associated with non-compliance.

Flexibility and Scalability

A defense-in-depth strategy offers flexibility and scalability. This allows you to adapt to evolving threats and business needs. New technologies and security measures emerge all the time. You can integrate them seamlessly into your existing security framework.

Furthermore, you can scale your security controls as your organization grows. This ensures that your cybersecurity strategy remains effective. As well as aligned with your expanding infrastructure.

Employee Education and Awareness

At Limbtec we firmly believe that defense-in-depth approach extends beyond technology. It encompasses employee education and awareness. Educating your employees about cybersecurity best practices can significantly reduce risk. Especially those coming from human error and social engineering attacks.

Training and awareness programs create a human firewall. This complements your technical controls. It’s also a key component of any defense-in-depth cybersecurity approach.

Protect Your Business from Today’s Sophisticated Cyber Threats

We are in an era where cyber threats are constantly evolving. They are becoming even more sophisticated with AI. A defense-in-depth cybersecurity strategy is a must. Having many layers of security can significantly enhance your protection against cyber threats.

What is Zero-Click Malware?

16th August 2023

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.

Top 7 Cybersecurity Risks of Remote Working, and what to do about them.

9th August 2023
Cyber Security Risks

Remote work has become increasingly popular in recent times. It provides flexibility and convenience for employees. Additionally, telecommuting reduces office costs for employers. Many also cite productivity benefits due to fewer distractions.

Research shows a 56% reduction in unproductive time when working at home vs. the office.

But there are some drawbacks to working outside the office. It’s crucial to be aware of the cybersecurity risks that come with remote and hybrid work. Keeping an eye on device and network security isn’t as easy. About 63% of businesses have experienced a data breach due to remote employees.

This news doesn’t mean that you must risk security to enjoy remote working. You can strike a balance. Be aware of the cybersecurity concerns and address them to do this. Below, we’ll discuss some of the top cybersecurity risks associated with remote work. As well as provide practical tips on how employees and employers can address them.

Remote Work Risks & Mitigation

1. Weak Passwords and Lack of Multi-Factor Authentication

Using weak passwords puts accounts at risk of a breach. Also, reusing passwords across several accounts is a big cybersecurity risk. Remote workers often access company systems, databases, and sensitive information from various devices.

To mitigate this risk, you should create strong and unique passwords for each account. Additionally, enable multi-factor authentication (MFA) whenever possible. This adds an extra layer of security by requiring a second form of verification. Here at Limbtec we use a password manager to make sure we have Very Strong passwords.

Employers can set up access management systems. These solutions help automate the authentication process. They can also deploy safeguards like contextual MFA.

2. Unsecured Wi-Fi Networks

Working remotely often means connecting to different Wi-Fi networks. Such as public hotspots or home networks that may not be adequately secured. These unsecured networks can expose your sensitive data to hackers.

To protect company data, use a Virtual Private Network (VPN). Turn on the VPN when connecting to public or unsecured Wi-Fi networks. A VPN encrypts the internet traffic. This ensures that data remains secure even on untrusted networks.

3. Phishing Attacks

Phishing attacks remain a prevalent threat, and remote workers are particularly vulnerable. Attackers may send deceptive emails or messages. These messages trick users into revealing their login credentials or downloading malicious attachments. To defend against phishing attacks, be cautious when opening emails. Especially those from unknown sources. Avoid clicking on suspicious links. Verify the sender’s email address.

Also, be wary of any requests for sensitive information. If in doubt, contact your IT support team to confirm the legitimacy of the communication.

4. Insecure Home Network Devices

Many remote workers use Internet of Things (IoT) devices. These include smart speakers, home security systems, and thermostats. These devices can introduce vulnerabilities to your home network if not properly secured.

To address this risk, make sure to change the default passwords on your IoT devices. Also, keep them updated with the latest firmware. Consider creating a separate network for your IoT devices. A “guest” network can isolate them from your work devices and data.

Employers can improve security for remote teams using an endpoint device manager. Such as Microsoft Intune, or similar. These devices make it easier to manage security across many employee devices.

5. Lack of Security Updates

Regularly updating your devices and software is crucial for maintaining strong cybersecurity. Remote workers may neglect these updates due to busy schedules or limited awareness. Cybercriminals often exploit vulnerabilities in outdated software to gain unauthorized access to systems.

To mitigate this risk, enable automatic updates on devices and software whenever possible. Regularly check for updates. Install them promptly to ensure you have the latest security patches.

6. Data Backup and Recovery

Remote workers generate and handle a significant amount of data. The loss or corruption of this data can be devastating. Implementing a robust data backup and recovery plan is essential.

Back up your important files to a secure cloud storage service or an external hard drive. This ensures that if a hacker compromises a device, your data remains safe and can be easily restored.

This has t oinclude all data that is held in the cloud, at Limbtec we do this by using a cloud to cloud backup.

7. Insufficient Employee Training

Remote workers should receive proper cybersecurity training. It helps them to understand security risks and best practices. Unfortunately, many companies neglect this aspect of cybersecurity. This leaves employees unaware of the potential threats they may encounter.

Organisations must provide comprehensive cybersecurity training to remote workers. This training should cover topics such as:

  • Identifying phishing emails
  • Creating strong passwords
  • Recognizing suspicious online behavior
  • New forms of phishing (such as SMS-based “smishing”)

The hidden dangers of free VPNs: Are you at risk?

7th August 2023
The hidden dangers of free VPNs: Are you at risk?

Are you aware that the rise in global VPN usage has skyrocketed? The reasons are clear as day: Virtual Private Networks offer increased security, anonymity, and allow access to geo-restricted content online.

But here’s the million-dollar question: Are all VPNs created equal?

The answer is a resounding no. And that has potential implications for your business.

Free VPNs, although tempting with their zero-cost allure, aren’t always what they promise to be. Why, you ask? Let’s take a closer look at free VPN services.

For starters, it’s important to understand that running a VPN service comes with substantial costs. Servers, infrastructure, maintenance, staff – these aren’t free.

So how do free VPN providers keep the lights on? Some employ tactics that could compromise your privacy and security.

Imagine this: You’re sipping your morning coffee, browsing the net through a free VPN, believing your online activities are private. In reality, your sensitive information might be collected and sold to the highest bidder.

Cyber criminals, advertisers, even government agencies could potentially get their hands on your data.

Shocking, isn’t it?

Moreover, free VPNs are notorious for injecting unwanted ads and tracking cookies into your browsing sessions. Ever wondered why you’re suddenly bombarded with eerily accurate ads? It’s probably your free VPN service cashing in on your browsing habits.

Now, consider the potential danger if an employee downloads a free VPN on a company device, or on their personal device that they use for work. Company data could be exposed, representing a significant business risk. Picture a scenario where your company’s sensitive data falls into the wrong hands – a chilling thought, isn’t it?

So, what’s the solution?

It’s crucial to educate your employees about the risks associated with free VPNs. Encourage the use of reliable, paid VPN services that guarantee no logging of data, robust encryption, and superior user privacy.

In fact, you may choose to provide one to them. If we can help you find the safest, most suitable VPN for your business, get in touch.

Remember, when it comes to online security, free often comes at a higher cost. Isn’t it worth investing a few ££ a month to protect your company’s valuable information?
