The rise of the cyberattack: How to keep your data ultra safe

Technology has undoubtedly changed the way we live, work, and shop. In most cases, this has brought vast improvements, such as the convenience of online shopping and the rise in automated systems within commercial buildings.

But along with the many advantages, there have been some downsides.

Cyberattacks have hit the headlines several times this year, with a number of big-name retailers falling foul of hackers. Research in June 2025 from the Royal Institute of Chartered Surveyors (RICS) found that more than a quarter of UK organisations suffered a cyberattack in the past year, a rise of 11% from the previous year.

The findings identified “operational technology” as presenting the biggest risk. This covers everything from automated heating and lighting systems to energy management and advanced security protocols.

It can be very unsettling if a business you’ve recently used, or frequently purchase from, has been a victim of a cyberattack. However, there are some simple actions you can take to keep your data as safe as possible.

Read on to find out more, and discover six steps for protecting your data.

As buildings adopt smart technology, they can become more susceptible to cyberattacks

The rise in cyberattacks can be, in part, attributed to changes in the physical environment of bricks-and-mortar premises. Where once these were simply buildings, they’re now smart buildings, with talking technology and integrated systems.

And with the increase in digital data comes an associated increased risk of security leaks.

Marks & Spencer was hit over the Easter weekend, in a cyberattack that has taken months for the retailer to recover from. According to the Guardian, profit losses were estimated to be around £300 million, with online orders paused for several weeks and contactless payments in stores temporarily suspended.

Cybersecurity company Periculo detailed other businesses which have fallen foul of cyberattackers.

Adidas also suffered a data breach in May, with cyberattackers gaining access to some customers’ names and contact details.

And, the Co-operative Group’s operations were severely disrupted after a cyberattack, with IT systems shut down and supply issues leading to empty shelves. Some member data was also breached.

While it can be disconcerting to see a company you’ve recently used fall foul of a cyberattack, try not to panic. Often, the incident will have only affected certain types of customers, or those in specific places. For example, the Adidas breach only impacted customers who had used their helpdesk.

Most organisations contact their customers after a breach, often to give some reassurance that they weren’t in the affected group. If you were unlucky and your data was compromised, they’ll usually give you some pointers about what to do next, and offer you access to a cybersecurity support service.

6 simple steps you can take to keep your data safe

While there are never any guarantees when it comes to online data, there are some actions you can take to keep your details as safe as possible, especially in the wake of a cyberattack on an organisation you frequently use.

1. Change your password

Passwords can be undeniably infuriating, but they’re there for a good reason: to protect your data. Even if your details haven’t been compromised, it’s still a good idea to change your password after a breach.

It can be tempting, but don’t use the same password for more than one account. Make it stronger by using a combination of uppercase and lowercase letters, numbers, and symbols, and avoid anything obvious like a birthday or child’s name.

Which? has created a helpful guide on creating passwords, such as using a “passphrase” instead of a password: a random collection of words put together. It also offers advice on a range of password managers, which can be a good way to securely store your passwords, as well as helping you to generate strong, unique codes each time.

2. Add two-factor authentication

This is an extra security step to prevent someone from trying to fraudulently use your details. It’s usually a code texted or emailed to you, which can only be used once and within a time limit.

It’s a good idea to use this whenever it’s an option; it only takes you a few seconds longer to log in, but it is an important security feature.

3. Be vigilant with your emails

Clever hackers know that organisations often send emails to customers after a cyberattack, and may use this to their advantage.

Be hyper observant, especially in the light of a cyberattack, so that you know who you’re dealing with. Most reputable organisations will address you by name, and won’t ask you for private information such as your password or username.

4. Check your credit record

Fraudsters using your personal details could try to commit identity fraud, taking out loans or credit cards in your name.

Keeping an eye on your credit rating can help you monitor that this is as you’d expect. For example, if you have a good credit score but are turned down for a financial product, this could raise a red flag.

5. Be wary of social media

It’s pretty easy for fraudsters to hack into social media accounts, so even if you think you’re talking to a friend or family member, you may not be.

If anyone asks you to transfer money, double-check using a different method first, such as phoning or texting them. Even if they’re saying it’s urgent, take the time to ascertain who you’re dealing with.

6. Avoid storing payment cards

Often given as an option for faster checkout, storing your payment cards might seem like a good idea. But for the sake of saving a relatively short amount of time, you could be agreeing to third parties being privy to your details.

It might cost you a couple more minutes at the checkout, but you could protect your personal information from being leaked.
