On December 9, 2021, Apache upended the cybersecurity industry by publishing a zero-day vulnerability (CVE-2021-44228) for its ubiquitous Log4j logging utility. Dubbed Log4Shell, the remote code execution flaw (CVSS score:10) allows an attacker to take control of a connected device and run malicious code, access sensitive data or alter its configuration. Because Logj4 is free and easy-to-use, it’s embedded (often deeply) in Java applications used by IT and OT platforms worldwide.

Live conferences are finally back, and the 11th annual AWS re:Invent did not disappoint.

As per usual, re:Invent was full of exciting product news and updates. Here are the major announcements that got our attention and some of the things Snyk was up to in Vegas.

In light of the numerous large-scale cyberattacks witnessed in the last year, 2023 promises to be an exciting time for cybersecurity. Outpost24 experts share their thoughts on what we can expect in the new year, and how to best prepare against new threats.

Azure Bicep is getting more popular by the day and is rapidly becoming the replacement for Azure Resource Manager (ARM) templates. In this post, I am going to go over some security fundamentals when using Bicep. If you are not familiar with Bicep then I recommend taking a look at the Microsoft Learn documentation to find out more.

In August 2021, threat actors started to exploit ProxyShell vulnerabilities in certain Microsoft Exchange Server versions. Today, not only is Kroll seeing actors continue to leverage ProxyShell in larger network intrusions but also now organizations must also be on guard for the so-called ProxyNotShell vulnerabilities, which surfaced in September 2022.

When the CrowdStrike Services team conducts a proactive security engagement, such as a Cybersecurity Maturity Assessment or Tabletop Exercise, it often uses CrowdStrike Falcon® Spotlight to identify what vulnerabilities exist in the environment. Unfortunately, this can be a disheartening experience, as many organizations we see have millions, even tens of millions, of unpatched vulnerabilities. It’s typical to see at least a quarter of those listed with a CVSS rating of Critical.
