Browse with confidence: Microsoft Edge’s security boost

3rd July 2023
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.

Stop! And think, before you act on that email

19th June 2023
Stop! And think, before you act on that email

How many times a day do you respond to an email without really thinking about its contents?  

Maybe it’s a request for some information. Perhaps it’s asking you to pay an invoice. All mundane stuff. But no sooner than you’ve hit send, you’ve fallen victim to a Business Email Compromise (BEC) attack.

A BEC attack occurs when a cyber criminal gains access to your business email account and uses it to trick your employees, customers, or partners into sending them money or sensitive information. They do this by impersonating someone senior, and abusing their position of trust.

It might sound like something that only happens to big corporations, but that’s not the case.

According to the FBI, small and medium-sized businesses are just as vulnerable to BEC attacks as larger ones. In fact, these attacks have cost businesses more than £20 billion over the past few years.

And Microsoft brings more bad news, with its recent findings showing that they’re getting both more destructive and harder to detect.

So, what can you do to protect your business from BEC attacks? Here’s our advice:

  1. Educate your employees: They are the first line of defence against BEC attacks. They need to know how to spot phishing emails, suspicious requests, and fake invoices. Train them regularly on cyber security best practice, like strong passwords, multi-factor authentication, and secure file sharing.
  2. Use advanced email security solutions: Basic email protections like antispam and antivirus software are no longer enough to block BEC attacks. You need more advanced solutions that use artificial intelligence and machine learning to detect and prevent these attacks in real-time. Look for email security providers that offer features like domain-based message authentication, reporting, and conformance (DMARC), sender policy framework (SPF), and DomainKeys Identified Mail (DKIM).
  3. Set up transaction verification procedures: Before transferring funds or sensitive information, establish a verification process that confirms the authenticity of the request. This could include a phone call, video conference, or face-to-face meeting. Don’t rely on email alone to confirm these types of requests.
  4. Monitor your email traffic: Regularly monitor your email traffic for anomalies and unusual patterns. Look for signs like unknown senders, unusual login locations, changes to email settings or forwarding rules, and unexpected emails. Make sure you have a clear protocol in place for reporting and responding to any suspicious activity.
  5. Keep your software up to date: Ensure that you’re always running the latest version of your operating system, email software, and other software applications. These updates often include vital security patches that address known vulnerabilities.

BEC attacks are becoming more common and more sophisticated, but with the right awareness, training, and security solutions, you can protect your business.

Don’t wait until it’s too late – take action today to keep your business safe.

Here’s how cyber criminals try to hack your accounts while you sleep

5th June 2023
How cyber criminals may hack your MFA

Have you ever felt frustrated by the flood of notifications from your multi-factor authentication (MFA) app?

Well, cyber criminals have too. And they’re taking advantage of “MFA fatigue” to try to gain access to your sensitive business data.

MFA is essential for keeping your data secure. It adds an extra layer of security to your apps and accounts by asking you to verify your identity in two or more ways, such as a password and a code sent to your phone.

The constant alerts can be overwhelming though.

Attackers know this and will bombard employees – sometimes in the middle of the night – with a constant stream of MFA notifications. Which makes it more likely someone will authenticate a login attempt through frustration, tiredness, or just to get the notifications to stop.

But now there’s a new weapon in the fight against MFA fatigue.

Microsoft Authenticator has introduced number matching as a way of making sure your MFA notification is from the correct login attempt, preventing cyber criminals from taking advantage of notification fatigue.

How does number matching work?

When you receive an MFA notification, the app will display a randomly generated number. You then need to input this number to authenticate the login attempt and prove you’re not a cyber criminal trying to access your business data.

That’s not all. Microsoft Authenticator also allows for biometric authentication, which means you can use your face, fingerprint, or other unique physical features to prove your identity and combat the threat of MFA fatigue attacks.

With these security measures in place, your business can stay ahead of cyber criminals and keep your sensitive data better protected.

If you already use Microsoft Authenticator, number matching is ready to use. Simply make sure your app is up-to-date, and you’ll be protected.

If you use another MFA system and want to look at how to make your security better or easier, we can help. Get in touch.

Criminals are exploiting AI to create more convincing scams

24th May 2023
Criminals are using AI to scam you

One of the many cool things about the new wave of Artificial Intelligence tools is their ability to sound convincingly human.

AI chatbots can be prompted to generate text that you’d never know was written by a robot. And they can keep producing it – quickly, and with minimal human intervention.

So it’s no surprise that cyber criminals have been using AI chatbots to try to make their own lives easier.

Police have identified the three main ways crooks have found to use the chatbot for malicious reasons.

  1. Better phishing emails

Until now, terrible spelling and grammar have made it easy to spot many phishing emails. These are intended to trick you into clicking a link to download malware or steal information. AI-written text is way harder to spot, simply because it isn’t riddled with mistakes.

Worse, criminals can make every phishing email they send unique, making it harder for spam filters to spot potentially dangerous content.

  • Spreading misinformation

“Write me ten social media posts that accuse the CEO of the Acme Corporation of having an affair. Mention the following news outlets”.  Spreading misinformation and disinformation may not seem like an immediate threat to you, but it could lead to your employees falling for scams, clicking malware links, or even damage the reputation of your business or members of your team.

  • Creating malicious code

AI can already write pretty good computer code and is getting better all the time. Criminals could use it to create malware.

It’s not the software’s fault – it’s just doing what it’s told – but until there’s a reliable way for the AI creators to safeguard against this, it remains a potential threat.

The creators of AI tools are not the ones responsible for criminals taking advantage of their powerful software. ChatGPT creator OpenAI, for example, is working to prevent its tools from being used maliciously.

What this does show is the need to stay one step ahead of the cyber crooks in everything we do. That’s why we work so hard with our clients to keep them protected from criminal threats, and informed about what’s coming next.

If you’re concerned about your people falling for increasingly sophisticated scams, be sure to keep them updated about how the scams work and what to look out for.

If you need help with that, get in touch.

3 essential security tools for every business

16th May 2023
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.

10 Common Tech Problems Plymouth Businesses Are Eliminating From Their Business Forever

9th May 2023

They say, “You get what you tolerate” and now more than ever, we’ve been conditioned to tolerate worse service at higher prices. Companies get a ‘free pass’ simply by saying phrases like “the labour shortage,” “because COVID,” or “inflation.”

But it doesn’t have to be that way.

While you may be able to still do business even with some less-than-stellar vendors in some areas, if all your computers were to suddenly stop working, your network go down, your files gone, chances are you’d be dead in the water.

Your business depends on technology, and you need to make sure everything is up and running RIGHT and you’re protected ALL the time.

Here’s a list of ten common problems, complaints and just downright failures in service we hear of all the time…and I’ll show you how to eliminate them in your business.

  1. When you call your IT company, your message goes to voicemail and you’re stuck waiting hours (or even days) for a call back so your problem gets resolved.
  2. You often must reach out multiple times to get a problem resolved and you need to check back to see what the status is and get a timeframe.
  3. Your IT company doesn’t proactively monitor, patch and update your computer network’s critical security settings daily (or at least weekly) leaving your entire business vulnerable to attacks.  
  4. Your IT company doesn’t offer proof that they are backing up ALL your data, laptops and devices.
  5. Your IT company doesn’t meet with you regularly (at least once a quarter) to report what they’ve been doing, review projects and offer new ways to improve your network’s performance instead of waiting until you have a problem to make recommendations.
  6. Your IT company doesn’t provide detailed invoices that clearly explain what you are paying for.
  7. Your IT company doesn’t explain what they are doing and answer your questions in terms that you can understand, NOT in “geek speak” and they don’t routinely ask if there’s anything else they can help with, no matter how small.
  8. Your IT company doesn’t proactively discuss cybersecurity with you or make recommendations for protecting your network from ransomware and offer employee training videos, so they don’t fall victim to a scam.
  9. Your IT company hasn’t provided you complete network documentation, and they hold the “keys to the kingdom” refusing to give you admin passwords so you’re totally helpless if something goes wrong and you can’t get a hold of them.
  10. Techs arrive late and dressed like they just got out of bed, and you cringe every time you need to make that call because they’ll make you feel dumb or like they are ‘doing you a favor’ even though you’re paying them!

If you’re tolerating any of these common problems, know that you don’t have to! You could be paying for substandard support and worse, not be keeping your company protected.

This could jeopardize your data and your network’s security and cost you thousands in lost productivity because you and your employees are spending time dealing with problems that shouldn’t exist.

If that’s the case, then it’s time you see what else is out there and make sure you’re getting what you pay for.

Microsoft 365 makes Multi-Factor Authentication easier

3rd May 2023
Multi Facto Authnetication made Easier

Microsoft is planning to enable Multi-Factor Authentication (MFA) directly in its Outlook app for many 365 business users.

MFA is a vital tool to help protect your online accounts from cyber criminals. It works by generating a second, single-use passcode every time you log into an account. It’s usually sent to an authenticator app on your phone that you have to download and set up first.

Security codes can also be sent via SMS text message, by a phone call, or you might be given a special USB key to plug into your computer.

The process is often made quicker by using a biometric login like your fingerprint or face ID. It’s a minor chore, but the protection it offers far outweighs the couple of extra seconds it takes to access your account.

Microsoft isn’t so sure about those extra seconds, though. If the tech giant can save you that time, it’s going to do it. That’s why it’s looking to streamline MFA for Microsoft 365 business accounts.

It’s rolling out the improvement by building MFA directly into the Outlook app in a feature called Authenticator Lite. Until now, it’s relied on a separate authenticator app or sending login codes.

There’s no news yet for those of us who want faster authentication on our personal PCs. If Microsoft does announce plans to make this feature available to more hardware or operating systems, we’ll update you with any news.

If you don’t already use MFA for your apps and online accounts, we recommend that all businesses implement it as soon as possible. The additional security it offers protects against the vast majority of today’s cyber threats.

For more help and advice about implementing MFA or getting the best from Microsoft 365, just get in touch.

The Bad Bots!

24th April 2023
Bot malware is a growing security threat

If we talk about ‘bots’ you’d be forgiven for thinking of the amazing AI chatbots that have been all over the news lately.

But this isn’t a good news story. Bots are just automated programs, and bot malware is a worrying new security risk you need to defend your business against.

Malware bots are particularly dangerous because they steal whole user profiles – that’s a complete snapshot of your ID and settings. This potentially allows cyber crooks to bypass strong security measures like Multi-Factor Authentication (MFA).

Usually, if a criminal steals your username and password, they still can’t access your account because they don’t have access to your MFA authentication method. But with your whole profile available to them, using your cookies and device configurations, they can trick security systems and effectively switch off MFA. 

Once profile information is stolen, it’s sold on the dark web for as little as £5.

And it’s not even super-sophisticated cyber criminals deploying this technique. Just about anyone can obtain your details and use them for phishing emails, scams, and other criminal activity.

Since 2018, 5 million people have had 26.6 million usernames and passwords stolen, giving access to accounts including Microsoft, Google, and Facebook.

All this means there are things you need to do – right now – to keep your profiles and your business protected from bot malware.

  • Update your antivirus software and keep it on at all times.
  • Use a password manager and Multi-Factor Authentication to keep your login credentials safer
  • And encrypt all your files so that, if anyone does access your profile, there’s very little to steal.

These are the things we help our clients with every day. If we can help you, just get in touch.

Cyber Security – What about your Mobile.

21st March 2023
Don't forget your phone when you think about cyber security

Our phones are a goldmine of private information. Just think of all the financial details, personal messages, banking apps, photos and contact information that live behind that little glass screen.

And if your team use phones for work, they’ll often have access straight into company systems – email, contact lists, network access, file systems. So if they’re not kept as secure as any other device in your workplace, they can become a gaping hole in your cyber security.

Criminals know this, of course, which is why they target us through our phones just as much as they do through our networks and servers.

But cyber crime isn’t the only concern. Just losing your phone, or having it stolen, can put your data at huge risk.

So, whether you issue company smartphones, or your employees use their own, you should make sure everyone implements some simple security steps to protect your data and avoid disaster.

What to consider

Start with making sure your people set up a PIN and a biometric login (like a fingerprint or face scan) to open the device.

Only install apps from trusted sources to make sure you’re using genuine software.

And enable Multi-Factor Authentication on all apps that store even a small amount of sensitive data.

Be careful about where you connect to Wi-Fi. If you work remotely or often connect to public networks, consider using a VPN – a Virtual Private Network – to add another layer of security. You never know who’s monitoring traffic on a public network.

Finally, ALWAYS make sure your phone is running the latest version of its operating software, and keep all apps up to date.

Smartphones have changed so much about the way we live – at home, and at work – but it’s too easy to take them for granted. And that could be a costly mistake.

If you need help to keep your smartphones safe, just get in touch.

Cyber attacks are getting smarter and bigger. Is your protection?

27th February 2023
Cyber Attacks are getting Bigger and smarter

Have you ever tried to buy tickets for a huge event and found that the seller’s website has collapsed under the weight of thousands of people all trying to do the same thing at the same time?

The ticket site falls over – usually temporarily – because the server is overloaded with traffic it doesn’t have the capacity for.

Criminal Distributed Denial of Service attacks – DDoS, for short – exploit the same principle.

When a DDoS attack targets a business, it floods it with internet traffic in an attempt to overwhelm the system and force it to fail.

This results in the business and its customers being unable to access services. That may trigger a temporary failure, or it could be more serious. Last year, the average DDoS attack lasted 50 minutes.

That may not sound like a long time, but it’s enough to create angry customers, or to bring business to a grinding halt. And downtime can be costly.

The really bad news is that DDoS attacks are not only lasting longer, but they’re becoming bigger, more sophisticated and more common.

Recently, the biggest ever reported DDoS attack was reportedly blocked. At its peak, it sent 71 million requests per SECOND to its target’s servers. Prior to that, the biggest reported incident stood at 46 million requests per second.

Worse still, more businesses are reporting being targeted by DDoS attacks where criminals are demanding huge ransoms to stop the attack.

What does this mean for you?

It’s important you check all your security measures are up-to-date and working as they should be. Are your firewalls up to the task, with DDoS monitoring and prevention tools set up? And is your team fully aware of the importance of staying vigilant?

We can help make sure your business stays protected. Just get in touch.
