Comment by Omer Dembinsky, Data Research Manager at Check Point Software: 

"Hackers continue to innovate. Last year, we saw an impressive 50% more cyber attacks per week on corporate networks compared to 2020, this is a significant increase. We have seen the number of cyberattacks peak towards the end of the year, mainly due to vulnerability exploitation efforts. Log4J. New penetration techniques and avoidance methods have made it much easier for hackers to carry out malicious intent. The most worrying thing is that we see some key social sectors being launched into the list of most attacked. The education, government and healthcare sectors are on the list of the 5 most attacked industries in the world. I expect these numbers to increase in the run-up to 2022, as hackers continue to innovate and find new methods of carrying out cyber attacks, in particular ransomware. We are facing a cyber pandemic. I strongly urge the public, especially those working in the fields of education, government and healthcare, to learn the basics of how to protect themselves. "Simple measures such as repairing, segmenting networks and educating employees can go a long way in making the world safer."
