If you use Google Chrome in your business, you’re probably familiar with extensions. These useful tools can enhance your browsing experience in countless ways, from blocking annoying ads to reducing distractions.

Extensions are incredibly popular because they can add so much functionality to your browser. But just as you need to be careful when installing new apps on your phone, you must also be cautious when adding new extensions to your browser. That’s because they come with a risk of malware.

It’s short for malicious software – that’s any software intentionally designed to cause damage to a computer, server, or network. Cyber criminals use malware to steal data, hijack systems, and even empty your bank accounts.

Google Chrome holds about 65% of the browser market share worldwide, making it the most popular browser by far. This popularity makes Chrome a prime target for cyber criminals. While cyber attacks sometimes exploit vulnerabilities in the browser itself, there’s an easier way to target Chrome users: Through malicious extensions containing malware.

Although Google keeps a tight watch on its Chrome Web Store, the risk is still there. A recent report claims 280 million people installed a malware-infected Chrome extension between July 2020 and February 2023. That’s a huge number and highlights the importance of being vigilant.

Surprisingly, many malicious extensions remained available for download on the Chrome Web Store for a long time. On average, malware-filled extensions stayed up for 380 days, while those with vulnerable code were available for about 1,248 days. One particularly notorious extension was downloadable for 8 and a half years before being removed.

So, how can you protect yourself and your business from these malicious extensions? Here are five steps we recommend.

1. External reviews: Since checking ratings and reviews on the Chrome Web Store isn’t always reliable (many malicious extensions don’t have reviews), look for external reviews from trusted tech sites to judge whether an extension is safe.
2. Permissions: Be cautious if an extension asks for more permissions than it should. If a new extension requests extensive access to your data or system, this could be a red flag.
3. Security software: Use robust software to catch malware before it can do any harm. This is your last line of defence if you accidentally install a malicious extension.
4. Necessity: Before installing any new software or browser extensions, consider whether you really need it. Often, you can achieve the same functionality visiting a website.
5. Trusted sources: Only install extensions from trusted sources or well-known software providers. This significantly reduces the risk of downloading a harmful extension.

Chrome is the most popular browser, which means it will always be a target for cyber criminals. Google’s security team works hard to review every Chrome extension to ensure they are safe, but it’s still crucial to be vigilant.

Imagine waking up one morning, turning on your computer, and finding that all your important files – everything from customer data to financial records – are locked. Tight.

And then a scary message pops up demanding a ransom fee to unlock them.

That’s ransomware in a nutshell. It’s a type of malicious software that hijacks your data and holds it for ransom.

How does it happen?

It usually starts with an innocent-looking email or link. You might get an email that seems legitimate, asking you to click on a link or open an attachment.

This is known as a phishing email, where the sender appears to be genuine but isn’t. Once you click, malicious software is silently installed on your system. From there, the cyber criminals quickly go to work.

They’ll be encrypting your files so you can’t access them. Then, you get that dreaded ransom note, demanding payment in exchange for a decryption key to unlock your files. Paying the ransom is a risky move because there’s no guarantee you’ll get your data back, and it just encourages the attackers to target more victims.

2023 was a particularly bad year for ransomware, with attacks surging after a two-year decline. According to a report, there was a huge increase in ransomware incidents, breaking a six-year record.

One reason for this spike is the rise of something called Ransomware-as-a-Service (RaaS). This model lets cyber criminals “rent” ransomware tools, making it easier than ever for them to launch attacks.

As a result, more businesses are finding themselves posted on data leak sites, with a 75% increase in the number of victims between 2022 and 2023.

Ouch.

And it gets worse. Attackers are getting smarter. They’re developing new variants of old ransomware, sharing resources, and using legitimate tools for malicious purposes.

They’re also working faster, often deploying ransomware within 48 hours of gaining access to a network. And they tend to strike outside of work hours, such as when you’re tucked up in your bed, so they’re less likely to be noticed.

If your business falls victim to a ransomware attack, the consequences can be devastating. You might face significant financial losses, not just from the ransom itself but also from the cost of downtime and recovery.

There’s also the risk of losing critical data if you can’t decrypt your files.

Your reputation could take a hit if customers find out their information was compromised. Oh, and your business operations could be severely disrupted, affecting your ability to serve your clients.

What can you do?

The most important question then: How can you protect your business from this growing threat?

• Start by educating your team. Make sure everyone knows how to spot phishing emails and avoid suspicious links and attachments
• Regularly back up your critical data and securely store those backups offline
• Keep your software and systems up to date with the latest security patches, and invest in strong security tools
• It’s also important to limit access to your data. Only give employees access to the information they need for their jobs
• Monitor your network for unusual activity and have a plan in place to respond to incidents quickly

If you do get hit by a ransomware attack, don’t panic. Work with cyber security experts (like us) to resolve the issue.

Remember, it’s best not to pay the ransom, as it only fuels the cyber criminals’ activities.

More and more businesses are making the smart decision to be proactive and invest in their cyber security defences. This is fantastic news, especially since stats show that about half of small and medium-sized businesses still have no cyber security measures at all.

If your business falls into that category, it’s time to change.

Cyber security might sound complex, but it starts with a few simple steps. Let’s talk about some basics you can put in place right away.

First, think about encryption and multi-factor authentication (MFA). Encryption is like putting your data in a secure vault. It ensures that even if someone intercepts your information, they can’t read it without the encryption key.

MFA adds an extra layer of security by requiring you to verify your identity using a second device, like your phone, whenever you log in. It’s a bit like needing two keys to open a lock instead of just one.

Another easy step is using a password manager. These generate long, random passwords for every account and remember them for you. Password managers make life easier and your business more secure in one package. Amazing.

Advanced monitoring tools are another great way to protect your business. They’re a little like security cameras for your digital space, always on the lookout for anything suspicious. These tools help detect unusual activity in your systems, giving you a heads-up if something’s not right.

And let’s not forget about protecting your business from phishing scams. These are attempts by criminals to trick you into giving away personal information by pretending to be someone you trust, like a supplier or a bank. Educating your team on how to spot these scams is crucial. If something feels off, it probably is.

Why is investing in cyber security so important?

• It protects your data
• Avoids financial loss
• And builds trust with your customers and partners

Your business data is valuable, and protecting it means safeguarding your business’s operations and reputation.

Cyber attacks can be costly, not just in terms of money but also time and resources. Prevention is ALWAYS cheaper than dealing with the aftermath of a breach. Plus, showing that you take security seriously helps build trust with your customers and partners. They need to know that their information is safe with you.

Here’s something not-so-fun but incredibly important to talk about: Malware attacks.

And it’s bad news. These scary cyber threats are hitting small and medium-sized businesses (SMBs) harder than ever before. That means you need to know how you can defend your business.

First things first, what exactly is malware?

Think of it as the digital equivalent of the germs that make you sick. Malware, short for malicious software, is like the flu virus of the cyber world. It’s designed to sneak into your computer systems or network and wreak havoc in all sorts of ways.

So, what kinds of malware are we talking about here?

Well, according to a recent report, there are a few major troublemakers: Information-stealing malware, ransomware, and business email compromise (BEC).

You might be wondering why you should care about malware. Let me set the scene. You’re running your business smoothly, minding your own business, when BAM! A malware attack hits.

Suddenly, your files are encrypted, your systems are locked down, and you’re being held hostage for ransom.

Sounds like a nightmare, right?

That’s the reality for many SMBs facing malware attacks. It’s not just about losing money – it’s about the potential damage to your reputation, your operations, and your customers’ trust.

But there are plenty of ways to fight back against malware and keep your business safe and sound:

Educate your team

Teach your employees to spot phishing emails (an email pretending to be from someone you trust), suspicious links, and other sneaky tactics used by cyber criminals. A little awareness goes a long way.

Armour up your devices

Make sure all your computers and devices are equipped with the best software to prevent attacks.

Back up, back up, back up

Regularly back up your data to secure offsite locations. That way, if you are attacked, you’ll have a backup plan (literally) to restore your files.

Fortify your network

Improve your network security with firewalls, encryption, and other powerful weapons. We can help with all of that.

Stay sceptical

Be cautious of suspicious emails or requests for sensitive information. When in doubt, double-check the sender’s identity and never click on risky links or attachments.

Have a plan

Prepare an incident response plan for dealing with malware attacks. Think of it as your emergency playbook, complete with steps for containing the threat, recovering your data, and reporting the incident.
