April 2023 saw some major cyber attacks, ransomware attacks and data breaches across the globe. The lists on this page cover all the major cybersecurity incidents that made news in the month gone by. We also include updates on new malware and ransomware discovered as well as vulnerabilities, warnings, reports and analysis from the world of cybersecurity.

The UK Cyber Security Breaches Survey 2023 was released recently. A worrying trend captured by the report was that smaller businesses appear to be identifying cyber breaches less than last year. This may reflect that cybersecurity is being given a lesser priority - a dangerous tendency given the increasing number of cyber risks and threats that loom large in the current economic climate.
In this post, we've created separate lists that capture the major ransomware attacks, cyber attacks and data breaches in April 2023. The idea is not to create panic or fear. The endeavour is simply to highlight that cybersecurity attacks are not going anywhere. If anything, they're rising in number and intensity.
While there is no wishing them away, the only thing business owners and organisations can do is to stay proactive in identifying them and having a solid plan to deal with them.
In this context, the UK Cyber Security Breaches Survey also pointed to the fact that while cyber resilience is much spoken of across the globe, only 21% businesses in the UK have a cyber incident response plan.
A Cyber Incident Response Plan contains agreed-upon steps and processes that an organisation will take when under attack. This helps to control the compromise and mitigate damage. It is important to have a plan that specifies individual roles and responsibilities, guidance on external and internal reporting and ways to protect the most critical assets.
Every business must accord importance to being prepared for a cyber attack. This can be achieved by reviewing or creating existing plans, policies and processes with the help of external cybersecurity experts like our Virtual Cyber Assistants.
Board engagement and corporate governance is another important aspect that needs to be improved upon. Executive training, enhancing board knowledge about the threats to their business, improving overall board engagement with cybersecurity are certainly critical if the below lists are anything to go by.
