Top 5 UK Cyber Incidents in 2021

2021 is over! And since we’re a couple of weeks into 2022, we thought it would be a good back at the UK’s tech industry in the last 12 months. In particular, we’re going to look back over cyber security incidents in the UK in 2021.

It felt like cyber security was in the news every week last year. From data breaches to ransomware attacks throughout the year, there was always some sort of threat businesses had to worry about. And unfortunately, we don’t think cyber threats are going anywhere – in fact, there are likely to be just as many if not more threats over the coming months.

Here are the top 5 cyber incidents that hit the UK in 2021.

2021 UK Cyber Incidents

  1. Guntrader

In July, UK based website Guntrader suffered a data breach, with around 112,000 unique email addresses being exposed. As well as email addresses, personal information was also exposed, including names, phone numbers, geolocation data, IP addresses and various physical address attributes (cities for all users, complete addresses for some). User passwords stored as bcrypt hashes were also exposed.

  1. Npower

In February, Energy firm Npower has closed down its app following an attack that exposed some customers’ financial and personal information. Customer accounts were accessed using login data obtained from other websites – a common technique used by hackers, known as ‘credential stuffing’. Data exposed included personal information, partial financial information and contact preferences.

  1. VoIP Providers

An ‘unprecedented’ cyber-attack has struck multiple UK-based providers of voice over internet protocol (VoIP) services, according to an industry body. It was unclear how many firms were affected, but it was reported that an overall threat has been made to the entire industry.

  1. Conti Group

In November, data on countless celebrities, politicians and heads of state appear to be in the hands of ransomware actors after a group using the Conti variant compromised a high-end jeweller. Tens of thousands of documents, including customer invoices and receipts, were leaked onto a dark web site.

  1. Spar

More than 300 Spar convenience stores were hit by a cyber attack in December, causing many to close. The attack hit the company’s computer systems, causing a “total IT outage” that has prevented staff from taking card payments and locked them out of emails.

Cyber Threats in 2022

2021 was an overwhelming year for cybersecurity. It is expected that such large corporate data breaches will only get worse. Hackers and the tools they use are becoming more sophisticated, while companies and governments struggle to keep up.
