We're almost into the second half of the year but the cyber attacks, data breaches and ransomware attacks are nowhere close to abating. May 2023 saw a fair share of high-profile cybersecurity incidents. We also received some major updates on attacks that happened earlier in the year. This article contains all that information and more!
Ransomware attacks continued their rampage in May 2023. Two cities, many healthcare organisations, an airline, educational institutions and tech giants - almost nobody seems to have been spared. Black Basta, LockBit, Black Cat continued to be the usual suspects with the new Money Message extortion gang making waves in every sector and demanding hefty ransoms.
Data Breaches in May 2023 were no less damaging. While most data breaches in the month gone by have been the work of criminal threat actors, some were caused due to technical errors. Interestingly, Tesla's massive data breach was, apparently, the work of an insider. The data handed over to one of Germany's top news organisations, allegedly, contains information of customers, employees, and business partners as well as thousands of customer complaints regarding the carmaker’s driver assistance system. A damaging data leak indeed!
And that's not all. Cyber Attacks continued to make news, be it on government websites, industry and education ministries and even on crypto exchanges.
The cost of these attacks and data breaches is immense and goes way beyond just monetary. While you do lose money in recovering from the attacks and/or in regulatory fines, you also lose customer trust once their information has been compromised. The inconvenience caused to them by business disruption is another critical factor to consider.
This is why it has become increasingly important to focus on your cybersecurity resilience and Business Continuity Management. Business Continuity can be achieved by reviewing or creating existing plans, policies and processes with the help of external cybersecurity experts like our Virtual Cyber Assistants.
Executive training, enhancing board knowledge about the threats to their business, improving overall board engagement with cybersecurity are also critical.
