The New Year has started and the cyber criminals are back with a bang. January 2023 has presented us with an exhaustive list of cyber-attacks, ransomware attacks and data breaches which are captured in this blog.
Several high-profile organisations, including healthcare providers, educational institutions and government bodies, have reportedly become targets of cyber-attacks already at the start of the year. In this blog, we have listed out the recent major cyber attacks, ransomware attacks and data breaches in January 2023. Wherever the data was available, we have also added information on who the attackers were and what the business impact was.
As always, the idea is not to create panic or fear-mongering. It is merely to reiterate the fact that the threat of cyber attacks and ransomware attacks continues to grow, and it is essential for you to take action to protect your organisation in 2023. By staying informed, implementing strong security measures, and educating employees, organisations across the world can reduce their risk of falling victim to these attacks.
If you need help with strengthening your cybersecurity posture and/or creating and refreshing your cyber incident plans, policies and procedures you can do so conveniently and cost-effectively through services such as the Virtual Cyber Assistant. The virtual cybersecurity experts can also help you conduct risk assessments and evaluate your breach readiness. You could also use their services to achieve compliance and become ready for various cybersecurity certifications.

Ransomware attacks can be devastating to a business in both monetary terms as well as in terms of loss of reputation. However, they can be prevented by following best practices such as regularly updating software, backing up files, enabling firewalls, being cautious with email attachments, using strong passwords, enabling pop-up blockers, installing anti-virus software, and being cautious when clicking links. By taking these steps, you can help protect yourself from ransomware attacks and ensure that your business critical data and sensitive information stays safe.

Cyber attacks in January 2023 continued to make headlines and cause widespread damage to individuals and organisations. The frequency and severity of cyber attacks has also risen, making it more important than ever to stay informed and take proactive measures to protect against these threats..jpg?width=200&height=133&name=186521217_m%20(1).jpg)
One of the most significant ways in which you can reduce your organisational vulnerability is to train the weakest link in the chain - the human element. Effectively training your staff in cybersecurity best practices and cyber incident response is one of the time-tested ways of reducing exposure to basic online threats.
You can also conduct Cyber Attack Tabletop Exercises for the board and management that helps them understand your organisational threat landscape better and improves their awareness of contextual business risks.
