Last month, the Splunk Threat Research Team had 3 releases of new security content via the Enterprise Security Content Update (ESCU) app (v4.31.0, v4.31.1 and v4.32.0). With these releases, there are 7 new analytics and 23 updated analytics, now available in Splunk Enterprise Security via the ESCU application update process.

Content highlights include:

  • The new analytic Windows Process Writing File to World Writable Path detects a process writing a file, specifically a .txt, to a world-writable path. This technique has been used by APT29-related campaign adversaries.
  • We added 6 new analytics and updated 6 existing analytics focused on AWS, detecting critical security events such as attempts to disable or modify CloudTrail logging, unauthorized container uploads to Amazon Elastic Container Service (ECR), and suspicious Identity & Access Management (IAM) group deletions.
