Log4j: the problem you can’t ignore now has an easy fix

By now, hopefully all readers not only know about the Log4j vulnerability that led to a surge in December cyber crime, but have taken action to correct it. For those who haven’t yet protected themselves, we provide a list of helpful resources below.

As background, Log4j is an open-source, Java-based logging utility widely used by enterprise applications and cloud services maintained by the Apache Software Foundation. It was recently discovered that all Log4j versions can be exploited by an attacker to perform unauthenticated remote code execution. This creates an array of risks not just on Linux servers, but on Mac and Windows, as well.

Due to the ease of exploitation and the breadth of applicability, ransomware actors began leveraging this vulnerability immediately. Here are resources for learning how to protect yourself NOW:

Easy steps for general cyber protection

The U.K.’s National Cyber Security Centre (NCSC) recently shared a helpful list of vital cybersecurity steps all organizations should take to protect themselves. Here are a few we consider most foundational:

  • Check your system patching: Ensure your users’ desktops, laptops and mobile devices are all patched
  • Verify access controls: ask staff to ensure that their passwords are unique to your business systems and are not shared across other, non-business systems
  • Ensure your defenses are working: check antivirus and firewalls
  • Test your backups: confirm that your backups are running correctly
  • Phishing response: ensure that staff knows how to report phishing emails

Are you certain your company’s network is truly up-to-date with the basic cybersecurity protections listed above?
