v4.42.0
Total New and Updated Content: [18]
Key Highlights:
Splunk Vulnerabilities: This release introduces key detections for recently disclosed Splunk vulnerabilities, including issues like disabling KVStore via CSRF, image file disclosure in PDF exports, and persistent XSS attacks. It also covers critical vulnerabilities such as remote code execution through arbitrary file writes and sensitive information disclosure in low-privileged user sessions and DEBUG logs. These detections enhance monitoring for exploitation attempts, improving Splunk's defenses against potential attacks and data breaches.
CISA AA24-241A : This new analytic story delivers detections tailored to identify malicious usage of PowerShell Web Access (PSWA) in Windows environments. These new detections focus on monitoring PowerShell Web Access activity through the IIS application pool and web access logs, providing enhanced visibility into suspicious or unauthorized access. The story introduces two key detections: "Windows Identify PowerShell Web Access IIS Pool" and "Windows IIS Server PSWA Console Access," which track the creation and usage of PSWA sessions, anomalies in IIS pool configurations, and unusual patterns of console access. By improving detection of PowerShell Web Access exploitation, we can defenses against potential privilege escalation, lateral movement, and remote code execution attempts within Windows infrastructures.
In addition to these updates, the detection logic for "Windows AdFind Exe" and "Linux Auditd Change File Owner To Root" has been improved based on customer feedback. These enhancements provide more accurate identification of AdFind tool usage in Windows environments and better detection of unauthorized file ownership changes to root in Linux systems, further fortifying defenses against privilege abuse and lateral movement techniques across both platforms.

v4.37.0
Key Highlights
Enterprise Security Content Updates version 4.37.0 introduces new detections focused on emerging threats like AcidPour, Gozi Malware, and ShrinkLocker. These analytics identify sophisticated techniques used by these malware families to compromise Windows environments, primarily through registry modifications. The update includes detections for attempts to configure BitLocker, delete firewall rules, disable Remote Desktop Protocol (RDP), alter Smart Card Group Policy, modify firewall rules, and change Outlook WebView settings. By monitoring these critical registry changes, security teams can more effectively identify potential compromises and swiftly mitigate risks associated with these advanced malware variants.We have also published a detailed blog on Acid Pour Wiper Malware and the various TTPs used by this wiper malware.
This release also contains detections for identifying exploitation of the following vulnerabilities:
- CVE-2024-5806, published by Progress Software, describes an improper authentication vulnerability affecting the MOVEit Transfer SFTP service that can lead to authentication bypass.
- CVE-2024-29824, published by ZDI and Ivanti, concerns an enterprise endpoint management solution and describes a SQL injection resulting in remote code execution with a CVSS score of 9.8.
- CVE-2024-37085, published by Broadcom, impacts VMware ESXi hypervisors. Successful exploitation of this flaw allows attackers with sufficient Active Directory permissions to gain full access to an ESXi host configured to use AD for user management by re-creating the default 'ESXi Admins' group after it has been deleted from Active Directory.
