In our recent webinar, Log4j Log4Shell Vulnerability Explained: All You Need To Know, our Senior Director Security Research expert Shachar Menashe shared information on the security issue and how to detect and remediate it. We are happy to share additional information in the following Q&A, based on the questions raised during the webinar.
Just when the Microsoft Exchange exploit CVE-2021-26855 thought it would win the “Exploit of the year” award, it got unseated by the – still evolving – Log4J exploit just weeks before the end of the year! Had somebody asked Sysadmins in November what Log4J was then I suspect that the majority would have had no idea. It seems that the biggest challenge the Log4J exploit poses for Sysadmins is simply the fact that nobody knows all the places where Log4J is being used.
Cyberattacks are constantly evolving as criminals discover new ways to crack strong networks or automate attacks to target vulnerable systems. Nowadays, it seems as if cyberattacks are everywhere you look. In 2021, we faced many new attack vectors as the shift to remote work challenged traditional work operations, and we are likely to see those continue well into 2022.
In cyber security, threat hunting is the act of proactively searching and monitoring networks, systems, endpoints, datasets etc. to identify any malicious behaviours or patterns that are not detected by existing security tools.
CrowdStrike is proud to announce that Armis, Cloudflare and ThreatWarrior have joined the open CrowdXDR Alliance. The addition of these industry leaders enhances XDR with telemetry from cloud, network and Internet of Things (IoT) solutions.This best-of-platform approach to XDR will help solve real-world productivity challenges that security teams face by empowering them to identify and hunt threats at accelerated speed and scale.
Due to the recently discovered Log4Shell vulnerability, and to support the tremendous effort being mounted by the community to address it, we are happy to announce that we are increasing the free test limit in Snyk Open Source! This means that any developer, no matter the company or project, can now use Snyk Open Source to find and fix Log4Shell with double the number of free tests, whether it’s within your IDE, your Git repositories, CI environments, or using the Snyk CLI.
As we all learn how to practically apply the emerging technology of Secure Service Edge (SSE), here is a significant SSE use case—perhaps the most significant, at least in our immediate future. Looking ahead to 2022, many businesses will no doubt have return-to-office plans at the front of their minds. But coming back to the office brings its own unexpected risks that security leaders need to be ready for.
Just a few days after CVE-2021-45046 was released and fixed, a third zero-day vulnerability was discovered in Apache Log4j, tracked as CVE-2021-45105. The bug was reported on December 15, 2021, and disclosed on December 18, 2021. This third vulnerability has received a CVSS score of 7.5 out of 10, whereas the first one known as Log4Shell (CVE-2021-44228) received the maximum CVSS score of 10 due to its criticality.
