Detect when System Manager successfully executes commands against an instance.
Detects any authentication activity (successful or failed) for emergency break-glass administrative accounts
Detects the potential abuse of the Linux Magic SysRq (System Request) key by adversaries with root or sufficient privileges
to silently manipulate or destabilize a system. By writing to /proc/sysrq-trigger, they can crash the system, kill processes,
or disrupt forensic analysis—all while bypassing standard logging. Though intended for recovery and debugging, SysRq can be
misused as a stealthy post-exploitation tool. It is controlled via /proc/sys/kernel/sysrq or permanently through /etc/sysctl.conf.

Detects the creation of a new user account. Such accounts may be used for persistence that do not require persistent remote access tools to be deployed on the system.
This rule detects instances where PowerShell (powershell.exe or pwsh.exe) spawns 'node.exe' with command-line arguments containing '-e' and the process path is located within the 'AppData\Roaming' or 'AppData\Local' directories. This behavior can be indicative of malicious activity, such as the execution of Node.js-based scripts or malware by PowerShell, potentially for persistence or further execution within user-specific application data folders.
Detects various sensitive configuration modifications in AWS that could indicate malicious activity, such as privilege escalation, defense evasion, or data exposure. This rule looks for a curated list of API calls related to changes in IAM, EC2 security groups, S3 bucket policies, and logging configurations.
This rule detects new device registrations in Azure Active Directory (AAD) that originate from an IP address not previously associated with the user's account within the last 29 days. It filters out registrations from corporate IP ranges and common mobile operating systems (iOS, Android) to reduce noise. The rule categorizes the risk level of the IP address based on historical sign-in counts, focusing on 'High Risk - New IP' events. It then enriches these events with additional sign-in details like device name, risk level during sign-in, country, and city.
Detects attempts to exploit the Triofox authentication bypass vulnerability (CVE-2025-12480) by sending a request with a 'localhost' Host header from an external IP address to access administrative pages. This allows an attacker to create a new administrative account.
This detection looks for administrative activity that creates or updates Cross-Tenant Access Settings or Cross-Tenant Identity Synchronization Settings in Microsoft Entra ID (Azure AD). These settings control how identities, claims, and trust relationships are shared between Microsoft Entra tenants.

Show when a monitor or a span/rspan is setup or modified
Detects the Installation of a Exchange Transport Agent
This rule detects the presence of 'activeMQConnectionURL' and 'tcp://' within HTTP response bodies, which is indicative of a Commvault server exposing its hostname or connection details. This information could be leveraged by attackers for reconnaissance or to identify vulnerable Commvault instances.
Detects the creation of a new administrator account on a Fortinet FortiGate Firewall. This activity could indicate an attacker establishing persistence or escalating privileges within the network infrastructure.
Detects when a new administrator role assignment is created within Okta. This activity can indicate privilege escalation, where an attacker gains higher-level permissions, or persistence, where an attacker establishes a way to maintain access to the system over time.
This rule detects when GitHub's push protection feature is disabled. This feature helps prevent sensitive information, such as secrets, from being accidentally committed to repositories. Disabling it could indicate an attempt to bypass security controls, potentially allowing secrets to be exposed in code.
Detects when an administrator role is assigned to a user or group within Okta. This could indicate privilege escalation or persistence by an attacker, or a legitimate administrative action.
Detects when a full data export is initiated in Bitbucket. This event indicates that a complete backup or export of all data within the Bitbucket instance has been triggered. This could be a legitimate administrative action but also a precursor to data exfiltration by an attacker who has gained administrative access to the Bitbucket server.
