Detects attempts by a principal to modify, stop, or delete AWS CloudTrail logging configurations. Such activity is a common indicator of defense evasion during the early stages of a cloud-based attack to prevent audit trail capture.
Detects modifications to cloud storage access control configurations in Azure (containers/blobs) and GCP (storage buckets) that result in public or unauthenticated access. The rule uses lookups to filter out approved public assets before alerting.
Detects the use of PsExec or SC.exe to create services on multiple remote endpoints within a short time window. This pattern is characteristic of adversary-driven mass deployment of ransomware or other malicious payloads where remote execution via Windows service control is used to move laterally across a network.
Detects modifications to SAML identity providers, federation settings, and trust configurations in AWS and Azure AD/Entra where the signing certificate fingerprint does not match a known-good baseline, and no corresponding change ticket is detected in the raw logs.
Detects the execution of known Active Directory reconnaissance tools, specifically AdFind and SharpHound/BloodHound. These tools are commonly used by adversaries to enumerate domain objects, users, computers, groups, and trusts, which are essential precursors to further lateral movement and privilege escalation within a domain environment.
Detects the installation of the Windows Subsystem for Linux (WSL) feature via dism.exe or wsl.exe, or the execution of wsl.exe for non-standard administrative tasks. This activity is often a precursor to running Linux-based tools or malware on a Windows host.
Detects instances where an administrative user grants 'AllPrincipals' OAuth consent to a multi-tenant application that is unverified or lacks a trusted publisher. This behavior is indicative of an attacker tricking a global admin into granting broad permissions (e.g., Mail.Read, Files.ReadWrite.All) to a malicious application, bypassing per-user consent restrictions.
Detects remote command execution patterns associated with the Impacket suite (e.g., wmiexec.py, atexec.py, smbexec.py). The detection identifies cmd.exe processes spawned by WmiPrvSE.exe or svchost.exe that contain specific command-line arguments indicative of Impacket's remote execution behavior, such as output redirection to hidden administrative shares or temporary files.
Detects when a high-privileged administrative role is assigned to an Azure Service Principal. This technique is often used for persistent, stealthy control over a tenant, as service principals are not subjected to user-centric access reviews or MFA challenges. The rule triggers on both permanent and PIM-eligible role assignments.
Detects a service principal or application identity performing a burst of deletion operations across multiple Azure resource types, such as Storage Accounts, SQL Databases, Key Vaults, and Function Apps. This behavior is indicative of malicious activity, including potential cloud environment destruction or 'agentic' destructive operations similar to those observed in the Storm-3168 (JADEPUFFER) threat activity.
