Log4j: What you need to know

An exploitable, remote code execution-enabling security vulnerability in a popular Java logging library called Log4J has commanded the infosec community’s attention over the last couple of weeks. Log4J’s ubiquity, the vulnerability’s ease of exploitation, and the uncertainty around who or what might be running the open source library has left the industry scrambling to apply patches and develop security controls to detect or prevent related attacks.

Red Canary Director of Intelligence Katie Nickels has spoken to a few media outlets in an effort to help journalists, their readers, and the infosec community make sense of the complex Log4J situation that’s been unfolding in recent days and weeks. While this vulnerability has the potential to be wide-reaching and highly impactful, organizations can go a long way toward protecting themselves by practicing defense-in-depth.

In an interview with NPR, Katie explained that the vulnerability may be new but that adversaries are using it to deploy known malware that leverages known techniques. She would go on to tell CNN that she’s most concerned about the impact this vulnerability could have on places like school districts, hospitals, and other small organizations with constrained budgets and limited tooling.

Katie also joined a panel of security experts on the ITSP magazine podcast to discuss what defenders can do about the escalating Log4j vulnerability.
