What has happened?
A very significant vulnerability in the “Log4j” library was discovered on Friday 10th December.

This is about as bad as it gets – an easily exploitable vulnerability in software that is used by most companies all over the world. Cybercriminals are already exploiting this vulnerability to hack into companies all over the world, and it is not being over dramatic to say that you need to be assessing your exposure to this vulnerability right now.

A cybercriminal could exploit this vulnerability to take complete control of any system that uses log4j. A simple command sent to a vulnerable system, from anywhere in the world, will allow them to take complete control of it.
