The cybersecurity threat is a very real one, and it is something that all businesses need to be concerned about. It does not matter what industry you operate in, or how big or small your company is, you are a target. A lot of small business owners make the grave error of believing that hackers are only out to catch the big fish. That is not the case. Any business with personal and payment data, which let’s face it is all businesses, is a target for fraud and other crimes. With that in mind, we are going to take a look at some of the worst data breaches that have hit the UK.


In November 2016, mobile phone network operator Three revealed that it had suffered a data breach, and then again, in 2019. They stated that a hacker gained access using an employee login during a database upgrade. At the time, Three claimed that data of births, addresses, phone numbers, and names were taken, but that financial information was not stolen. The company said 133,827 of its 9,000,000 customers were impacted. However, as time passed, they revealed that the breach was worse than expected. The company went on to admit that 76,373 more customers were victims of the breach.
