This is the second in a two-part series discussing a still-unpatched userland Windows privilege escalation. The exploit enables attackers to perform highly privileged actions that typically require a kernel driver. Part 1 of this blog series showed how to block these attacks via ACL hardening. If you haven’t already, please read the first part of this series, because it lays an important foundation for this article. Interested readers can also check out the excellent Unknown Known DLLs...

At ElasticON Global 2021, the team behind Elastic Security shared how we’re building the future of Limitless XDR (Extended Detection & Response) by unifying the capabilities of SIEM, endpoint security, and cloud security. With Limitless XDR, practitioners can prevent, detect, and respond to the threats of today and tomorrow.

Here’s what security leaders need to do in the face of rising stress levels and cyberattacks Nearly 9 out of 10 CISOs say their existing systems secured their enterprise through a shift to remote work, an ongoing labor shortage, and a huge spike in cybersecurity attacks. But that success came with a price: 64% say they’re more stressed out than they were a year ago. How can CISOs navigate a new set of challenges in 2022, while also regaining some much needed balance?

The Elastic Infosec Detections and Analytics team is responsible for building, tuning, and maintaining the security detections used to protect all Elastic systems. Within Elastic we call ourselves Customer Zero and we strive to always use the newest versions of our products.

According to FBI Director, Christopher Wray, when it comes to ransomware disruption and prevention, “...there’s a shared responsibility, not just across government agencies but across the private sector and even the average American.” At Elastic, we’re here to help state and local governments. Ransomware attacks cost the U.S. government more than $18.9 billion in 2020 alone.

On August 21, 2021, the Cybersecurity and Infrastructure Security Agency (CISA) released an urgent notice related to the exploitation of ProxyShell vulnerabilities ( CVE-2021-31207 , CVE-2021-34473 , CVE-2021-34523 ). By chaining these vulnerabilities together, threat actors are compromising unpatched Microsoft Exchange servers and gaining footholds into enterprise networks.

Since its inception, Elastic Security has had a clear mission: to protect the world's data and systems from attack. We started with SIEM, built on top of the Elastic Stack, applying its fast and scalable search capabilities to detect security vulnerabilities across all threat vectors. Next, we joined forces with Endgame to integrate endpoint security into Elastic Security, and allow customers to prevent, detect, and respond to attacks from a single, unified platform.

As a powerful search engine, Elasticsearch provides various ways to collect and enrich data with threat intel feeds, while the Elastic Security detection engine helps security analysts to detect alerts with threat indicator matching. In this blog post, we’ll provide an introduction to threat intelligence and demonstrate how Elastic Security can help organizations establish robust cyber threat intelligence (CTI) capabilities.
