Detects network connections attempting to access Kubernetes API endpoints related to secrets. This could indicate an adversary trying to enumerate or exfiltrate sensitive credentials from a Kubernetes cluster.
Detects AzureHound or roadtx bulk enumeration of Microsoft Graph API endpoints using tokens obtained via CVE-2025-0309 CA policy bypass, characterized by high-frequency GET requests to /v1.0/users, /v1.0/groups, /v1.0/devices, /v1.0/servicePrincipals from Edge client IDs (f44b1140-bc5e-48c6-8dc0-5cf5a53c0e34 or 22098786-6e16-43cc-a27d-191a01a1e3b5) with password-only amr claim and no MFA.
This rule detects network activity indicating a potential modification or interaction with Microsoft Entra ID (Azure AD) multifactor authentication (MFA) settings. Specifically, it looks for POST requests to the Microsoft Graph API targeting authentication methods (e.g., phoneAuthenticationMethod), which may be indicative of an attacker modifying MFA settings to bypass security controls or register rogue authentication devices.
Identifies post-exploitation reverse shells resulting from the LiteLLM RCE vulnerabilities. The rule looks for processes initiated by 'litellm' (either directly or via python running litellm) that then spawn child processes with common reverse shell command line patterns such as 'bash -i', '/dev/tcp/', 'nc -e', or 'sh -i'.
Detects the use of the native Windows curl.exe utility to download a ZIP archive from a remote location, a technique used by the Potemkin Loader to retrieve malicious RMM components while avoiding PowerShell-based security controls.
Detects the use of conhost.exe with the --headless flag to execute Node.js payloads silently. This technique is used by EtherRAT to run its malicious JavaScript payloads without displaying a console window to the user, aiding in defense evasion.
Detects multiple executions of wscript.exe or cscript.exe within an hour that involve command-line arguments containing business-related keywords (e.g., Invoice, Payment) and script extensions (.vbs or .vbe). This behavior is often indicative of automated malware staging, such as malicious macro-enabled documents spawning script engines.
Detects WinRAR creating a malicious VBS/VBE script within the Windows Startup folder using NTFS Alternate Data Streams, a behavior associated with the exploitation of CVE-2025-8088 by the Gamaredon threat group.
Device Code Phishing Attempt
Cortex XDR
Detects attempts to abuse the device code flow targeting Microsoft Office and Authentication Broker applications from unmanaged, non-compliant devices with unbound tokens. This activity is indicative of a phishing attack where an adversary is trying to steal application access tokens.
Detects the creation of Kubernetes pods with dangerous security settings that could lead to container escape or privilege escalation. This includes pods configured with hostNetwork enabled, allowing privilege escalation, running as root (UID 0), or abusing capabilities.
