In today’s increasingly digital world, it’s more important than ever to be aware of the risks your small business could face online. Cybercrime can impact businesses in several ways, and a cyber-attack has the potential to cause financial and reputational damage to a small business or sole trader.

As businesses of all sizes know, building a great reputation and earning customer trust takes years of hard work. Without the appropriate precautions in place, this can be destroyed in minutes if the business is targeted by a cyber-attack.

Such events are not reserved for multi-million-pound organisations – cyber-attacks on small businesses can also prove costly. These attacks can be performed at lightning speed – sometimes all it takes is the simple click of a link – but the effects can be wide-reaching. Learn what a cyber-attack is and how to prevent cyber-attacks and keep your small business flourishing with protection.

What is a cyber-attack?

A cyber-attack is a criminal activity where a computer system, network or application is attacked or hacked with the aim of stealing, destroying or holding data to ransom.

Cybercrime poses an ongoing threat to small businesses. Therefore, it’s important to understand what a cyber-attack is, what one looks like, the measures you can take to safeguard your business and how to act if you fall victim to any form of cybercrime.

What are the cyber statistics in the UK?

To understand the threat of cyber-attacks on small businesses, here's a look at some vital statistics on cybercrime against small firms and UK businesses.

The results of a GOV.UK survey(external link) released in March 2020 confirms cyber security breaches are becoming more frequent. It found 46% of UK businesses and charities reported a cyber-attack during the year. Of those, 33% claimed they experienced a cyber breach in 2020 at least once a week – up from 22% in 2017.

The average mean cost of a cyber security breach for a small business in 2019 was £11,000. This figure includes costs such as ransom payments, hardware replacements and indirect factors such as business interruption.

Types of cybercrime

  • Phishing attack : Hackers use phishing to get victims to part with personal data. This usually comes via a link presented in an email, SMS or instant message

  • SQL injection: An SQL injection happens when a cyber-criminal embeds harmful code into a webpage or application to access data.

  • Malware: Malware is malicious software designed to cause harm to a targeted computer or server. Viruses and worms are malware, as is ransomware, which is often launched as part of a phishing attack.

  • Denial-of-Service attacks : A denial-of-service cyber-attack is performed by hackers to halt the operation of an online service and might be carried out by inundating a system with requests or traffic, rendering it unusable.

  • Man-in-the-Middle attacks: During a man-in-the-middle cyber-attack, a cyber-criminal will intercept conversations, transactions and the transfer of data between the victim and a service they’re trying to use.
