These minimum viable secure configuration baselines are part of CISA’s Secure Cloud Business Applications (SCuBA) project.įor additional information and guidance, CISA and the FBI encourage network defenders to take the measures listed in this CSA to reduce the likelihood of similar activity and posture for detection. Note: See CISA’s Microsoft Exchange Online Microsoft 365 Minimum Viable Secure Configuration Baselines. For mitigations that are classified as preventative measures (e.g., steps to take to reduce the risk of network categorized exposure), CISA and FBI strongly encourage that FCEB agencies and critical infrastructure organizations ensure Audit Logging is enabled. Organizations that identify suspicious, anomalous activity should contact Microsoft for proceeding with mitigation actions due to the cloud-based infrastructure affected, as well as report to CISA and the FBI. The goal of this CSA is to enhance organizational cybersecurity posture and position organizations to detect similar malicious activity via implementing the listed logging recommendations. The vulnerability is mitigated by the fact that Drupal cores use of the ArchiveTar library is not vulnerable, as it does not permit symlinks. After reporting the incident to Microsoft, network defenders deemed the activity malicious. The Drupal project uses the pear ArchiveTar library, which has released a security update that impacts Drupal. In June 2023, a Federal Civilian Executive Branch (FCEB) agency observed unexpected events in Microsoft 365 (M365) audit logs. Recommended actions:The Cybersecurity and Infrastructure Security Agency (CISA) and Federal Bureau of Investigation (FBI) have released a joint Cybersecurity Advisory (CSA), Enhanced Monitoring to Detect APT Activity Targeting Outlook Online, to provide guidance to agencies and critical infrastructure organizations on enhancing monitoring in Microsoft Exchange Online environments.
