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.

To protect your home from an intruder you make sure your doors and windows are all locked and secured. You might go further: build a fence around the perimeter, perhaps even get an angry-looking dog to stand guard.

But there’s no point going to all that effort if someone’s already broken in and set up camp in the basement.

Yet that’s the security policy of thousands of big businesses trying to protect their data from cyber criminals.

They do many of the right things. They invest in security software. They take a strong, multi-layered approach to security – including all the things we recommend, like multi-factor authentication, encryption, reliable backup systems and staff training.

But they don’t pay enough attention to detection and response. That involves constantly scanning systems for any sign that a crook may have gained entry somewhere, and having a process to stop an attack in its tracks.

A new study shows that only a third of businesses place detection as their main priority, while two thirds say prevention is their primary focus.

That means, they could be building 10-foot walls around their systems with intruders already inside.

In-house security teams might be super-confident in the security measures they’ve put in place. But the data suggests that they’re being too complacent. The study reveals that more than eight in ten businesses experienced more than one data breach last year – even with good security in place.

Criminals are constantly finding ways to evade security. That tells us that we need to take a rounded approach, with strong prevention AND detection policies providing the best protection against today’s determined criminals.

If you employ anyone aged between 16 and 19, you need to pay special attention to the cyber security training you’re giving your team.

A new study has revealed that a host of worrying online behaviour has become almost normalised among many young people. And much of this activity is illegal.

We’re not talking serious cyber crime such as ransomware attacks or stealing data.

But one in three 16 to 19-year-olds have admitted to digital piracy; and a quarter have tracked or trolled someone online.

Most of these behaviours may not directly affect your business. But some are so commonplace that too many young people view them as a part of everyday life.

That’s not something you want them bringing to work.

Casual software piracy or illegal downloads on devices used for work could open the door to a massive security breach.

The answer is simple: Hold cyber security training for all your employees on a regular basis.

This training should:

• Highlight the impact of bad online behaviour and potential for security breaches
• Help everyone understand how this kind of activity can harm people – and your business
• Make everyone aware of the scams and attacks that your business is vulnerable to, as well as the part they play in keeping everyone protected
• Make the consequences clear for anyone found to be engaging in this behaviour

If this is something you need some expert help with, it’s what we do. Get in touch.

 

Another day, another scam. And this is a sneaky one.

Cyber criminals are getting smarter. This recent malware threat is unusually smart. It impersonates a highly trusted brand name to get a foot in the door.

Targets receive a convincing looking email that appears to come from a widely used e-signature platform.

Attached to the email is a blank image that’s loaded with empty svg files, which are carefully encoded inside an HTML file attachment (stay with us here).

In short, it’s very clever and it’s tricking its way past a lot of security software.

That puts businesses like yours at risk. Because code within the image sends people to a malicious URL.

Open the attachment and you could unwittingly install malware onto your device – or even your network – which risks exposing your data and leaving you open to a ransomware attack.

Recently, there’s been a wave of HTML attachment attacks on small and medium sized businesses, so it’s clear that companies need to take action to stay ahead of the criminals.

If you use software to sign documents electronically, double-check that emails are genuine before opening any attachments.

There’s a reason why the criminals have chosen to impersonate a trusted name.

Taking things a step further, you could block all emails with this type of attachment, to prevent employees from being exposed to scam emails in the first place.

With its huge dominance in the workplace, Microsoft’s Windows has become the prime target for cyber criminals. They’re looking to access your information, disrupt your business, or hold your data to ransom.

Tens of millions of attempted malware attacks were discovered throughout this year, and a massive 95% of those threats were targeted at Windows.

The vast majority of attacks are unsuccessful, but those that do succeed can create havoc for the affected businesses. So you need to be sure that you’re taking all possible precautions to protect your business and your data.

• Hardware and software companies release regular updates to address threats to Windows users, as well as security patches designed specifically to deal with new risks. These should all be installed as soon as they become available.

• Your people should be regularly trained in how to spot cyber security threats and what to do if they suspect one.

• And because it’s not possible to protect every business from 100% of all threats, it’s also important that you have a strong resilience plan in place.

This should detail exactly how your business should react if it falls victim to a cyber attack and who should be notified to take action. Everyone in the company should have access to this document and know to report any potential attack as quickly as possible – that’s the best way to lessen its impact.

If you have an IT service provider, they’ll be able to make the best recommendations to keep your business safe and secure, train your people, and even provide monitoring to spot any potential danger before it becomes a problem.

This is something we do every day. So if we can help your business become more resilient, just get in touch.
