This rule detects outbound TLS connections from the internal network to external destinations where the server certificate is self-signed. It identifies connections where both the certificate issuer and subject common names (CN) are present, which is often indicative of opportunistic encryption used by C2 infrastructure or malicious payloads. The rule includes a threshold to reduce noise by limiting alerts for the same source over a specific window.

Detects outbound network traffic attempting to reach known public DNS-over-HTTPS (DoH) resolvers. This rule monitors for specific SNI fields in TLS handshakes or HTTP/2 :authority headers that indicate communication with common third-party DoH services, which may be used to bypass internal DNS filtering and monitoring controls.

This rule detects potentially malicious OAuth application consent grants in Microsoft Entra ID (formerly Azure AD). It monitors for consent events involving high-risk scopes by non-verified publishers, instances of admins attempting to bypass consent requirements, and follows up by checking for unusually high activity (sign-ins or resource access) from the newly consented application within a short timeframe.

This rule identifies potential MFA fatigue attacks by detecting multiple MFA denial or failure events for a user within a 30-minute window, followed by a successful authentication for the same user in the same time frame.

Detects outbound network traffic containing cleartext Windows command shell banners, which is highly indicative of a reverse shell connection where a remote attacker has established interactive command-line access to a compromised host.

This rule monitors incoming HTTP requests for the use of PHP stream wrappers (e.g., php://, data://, expect://, etc.). Such wrappers are often leveraged by adversaries to perform Local File Inclusion (LFI) or to achieve Remote Code Execution (RCE) by manipulating input parameters in vulnerable web applications.

This rule detects potential OS command injection attempts in HTTP request parameters by monitoring for common shell command separators and subsequent execution of suspicious system binaries (e.g., sh, bash, curl, wget, python).

Detects established TLS outbound connections to external networks on ports other than standard ones (e.g., 443, 465, 587, 993, 995, 8443, 9443). This behavior may indicate a covert C2 channel or unauthorized data exfiltration attempting to bypass standard firewall controls.
