​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.

Airports, hotels, cafés, even shopping malls, offer public charging points where you can boost your phone or laptop battery on the go.

They’ve been in the news after the FBI recently tweeted advice to stop using them. Crooks have figured out how to hijack USB ports to install malware and monitoring software onto devices as they charge.

The security risk of “juice jacking” was long thought to be more theoretical than real, but the tech needed to carry out an attack has gotten smaller and cheaper and easier to use. This means less sophisticated criminals are now turning their hand to it.


So how does it work?


The most common charging cables – USB-C and lightning – are dual-purpose. They have pins for charging and pins for data.

When you charge your device, you only use the charging pins. But a compromised charging port – or a cable that someone has left behind – could use both charging pins and data pins without you knowing.

When they use the data pins, criminals can install malware onto your device that gives them access to your credentials and other data. It’s a little like plugging your phone into someone else’s laptop.

To avoid the risk, the best solution is to always carry your own charger and cable, and plug it into a power outlet. If you have no choice but to use a public USB port, invest in something called a USB data blocker. This prevents data being transferred, but the device will still charge.

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 emailsUntil 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.
 

2. 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.
 

3. 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.

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.

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.

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 tooverwhelm 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.

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.
