Biggest Cybersecurity News of March 2023

Amongst the biggest headlines of March 2023 is the latest zero-day exploits hitting Fortra’s GoAnywhere software and by extension several major organisations that used the software. Luxury brand retailer Saks Fifth Avenue, the City of Toronto, consumer goods giant Procter & Gamble, mining company Rio Tinto, and the U.K.’s Pension Protection Fund (PPF) are just amongst the few large organisations to have been hit by Cl0p ransomware as a result of the GoAnywhere attack. 

The other biggest news of the month? The major 3CX supply chain attack that has left millions at risk. The desktop app supposedly has 12 million users in 190 countries including big names like BMW, Honda, American Express, Toyota etc. 

These series of attacks have yet again turned the conversation to supply chain and third-party security. Businesses worldwide are beginning to recognise the cautionary tale that lies here. This is simply that one must focus on bolstering one's own cyber defences and making sure that their third-party vendors are doing the same.  

It has also turned the spotlight once again on making sure your incident response plans and processes are up to date and relevant. Enlisting the assistance of highly-skilled and experienced cybersecurity practitioners such as our Virtual Cyber Assistants can be of critical importance here.     

Cybersecurity specialists can not only help you refresh your incident response policies and plans but also help you evaluate your business's breach readiness. It is also time to invest in third-party assessments to ensure that your organisation stays as safe as possible in the current threat landscape.
