runZero Hour, Ep. 5: XZ Utils Backdoor

On this episode of runZero Hour, the runZero Research team dove into some hot topics, including:

XZ Utils Backdoor (CVE-2024-3094)

It’s the latest vulnerability that almost took down the digital world as we know it… and kept our researchers busy all weekend. Tune in to hear our research team break down the fascinating chain of events that unfolded with the XZ Utils backdoor and see what their analysis uncovered about the vulnerability itself. They’ll also be happy to show you how runZero can help identify potentially affected systems running recent OpenSSH versions on Fedora, OpenSUSE, Debian, and Kali Linux distributions.

Rapid Response Roundup

We also discussed our recent Rapid Responses for lighttpd web servers, D-Link NAS Storage products, PAN-OS, Flowmon, and more.
