Log4j Cyber Vulnerability – What You Need to Know

6 Jan

We wanted to let you know about a severe cyber vulnerability affecting businesses. You may have heard about it on the news or online.

The vulnerability has been identified in Log4j, a piece of software widely used by applications and other services across the internet, leaving businesses at risk of a cyber-attack.

If left unfixed, your systems could be exposed to cybercriminals, who could steal your passwords and data and infect your networks with malicious software. According to the National Cyber Security Centre (NCSC), this is potentially the most severe computer vulnerability in years.

What Actions Do You Need to Take?

You may be unaware of what software, servers or systems that your business uses that rely on the Log4j component, therefore it is vital that you follow the guidance issued by the NCSC. We would also recommend speaking with your IT department or vendors for assistance.

It is important to install any relevant updates and ‘patch’ your systems accordingly. If you have cyber insurance in place, this is crucial to ensure that you can still receive all of the benefits of your policy.

The NCSC has provided detailed instructions on how to install the latest updates wherever Log4j is known to be used, identify unknown instances of Log4j within your organisation and implement measures to monitor and protect your networks.
