Detects the execution of PowerShell with a Base64-encoded command line originating from Windows Explorer, a behavior consistent with the Potemkin Loader and ClickFix attack campaigns used to bypass string-based detection.
Detects the Potemkin Loader using the native Windows curl.exe utility to download a ZIP archive from a remote source, followed by the creation of a local .zip file. This behavior is used to bypass security controls by avoiding PowerShell-based download mechanisms.
Detects the loading of specific vulnerable drivers (Huawei, Topaz Antifraud, Tower of Fantasy, K7 Security) abused by DragonForce ransomware in Bring Your Own Vulnerable Driver (BYOVD) attacks to terminate security software.
Detects attempts to exfiltrate data through Microsoft Copilot Enterprise Search by identifying URL clicks containing specific keywords ('extract', 'embed', 'img') in the query parameters. This could indicate an adversary trying to extract sensitive information or embed malicious content.
Detects potential exploitation of the ToolShell remote code execution vulnerability (CVE-2025-53770) in on-premises Microsoft SharePoint servers. Attackers have been observed sending POST requests to the 'ToolPane.aspx' endpoint and subsequently dropping webshells with specific names in the SharePoint LAYOUTS directory.
This rule detects network events where a device attempts to access the Kubernetes API '/api/v1/namespaces/*/secrets' endpoint. This activity could indicate an attempt to enumerate or exfiltrate sensitive information (secrets) stored within Kubernetes, potentially by an attacker who has gained initial access to a pod or compromised a service account.
Detects Node.js executing the malicious setup.cjs script or easy-day-js with the --no-warnings flag, associated with the Mastra npm supply chain compromise.
Detects multi-stage cryptojacking campaign: autorun.dll sideload, silent msiexec install, and post-exploitation .NET binary process hollowing
This rule detects network events where the 'AdditionalFields' contain keywords commonly associated with Multi-Factor Authentication (MFA) such as 'otp', 'verify', '2fa', or 'mfa', and the 'RemoteIP' is a valid IPv4 address. This could indicate attempts to interact with, or potentially bypass, MFA mechanisms.
Detects the execution of Rubeus or Mimikatz with command-line arguments indicative of Kerberos attacks such as Pass the Ticket (PtT) or Golden Ticket generation. This rule specifically looks for keywords like 'rubeus ptt', 'kerberos::ptt', 'kerberos::golden', and 'mimikatz kerberos' in process command lines.
