Detects instances where an SSH service on an OpenCanary node has had a connection attempt.
Detects instances where a Telnet service on an OpenCanary node has had a login attempt.
Identifies when suspicious SAML activity has occurred in AWS. An adversary could gain backdoor access via SAML.
Detects sign-in with properties that are unfamiliar to the user. The detection considers past sign-in history to look for anomalous sign-ins.
Identifies an event where there are there are too many accounts assigned the Global Administrator role.
Detects a login attempt in Google Workspace flagged as a potential attack by a government-backed threat actor
Detects attempts to enable the guest account using the sysadminctl utility
Detects when a modification (create, update or replace) action is taken that affects mutating or validating webhook configurations, as they can be used by an adversary to achieve persistence or exfiltrate access credentials.
Detects instances where an SSH service on an OpenCanary node has had a login attempt.
Detects when an instance identity has taken an action that isn't inside SSM.
This can indicate that a compromised EC2 instance is being used as a pivot point.
This can indicate that a compromised EC2 instance is being used as a pivot point.
Detects the import of SSH key pairs into AWS EC2, which may indicate an attacker attempting to gain unauthorized access to instances. This activity could lead to initial access, persistence, or privilege escalation, potentially compromising sensitive data and operations.
Identifies when an user or application modified the federation settings on the domain.
Resource owner password credentials (ROPC) should be avoided if at all possible as this requires the user to expose their current password credentials to the application directly.
The application then uses those credentials to authenticate the user against the identity provider.
The application then uses those credentials to authenticate the user against the identity provider.
Identifies when an admission controller is executed in GCP Kubernetes.
A Kubernetes Admission controller intercepts, and possibly modifies, requests to the Kubernetes API server.
The behavior of this admission controller is determined by an admission webhook (MutatingAdmissionWebhook or ValidatingAdmissionWebhook) that the user deploys in the cluster.
An adversary can use such webhooks as the MutatingAdmissionWebhook for obtaining persistence in the cluster.
For example, attackers can intercept and modify the pod creation operations in the cluster and add their malicious container to every created pod. An adversary can use the webhook ValidatingAdmissionWebhook, which could be used to obtain access credentials.
An adversary could use the webhook to intercept the requests to the API server, record secrets, and other sensitive information.

Detects when a Microsoft Cloud App Security reported a risky sign-in attempt due to a login associated with an impossible travel.
Detects attempts to enable the root account via "dsenableroot"
Detects successful logon from public IP address via RDP. This can indicate a publicly-exposed RDP port.
Detects suspicious computer name samtheadmin-{1..100}$ generated by hacktool
The Reset-ComputerMachinePassword cmdlet changes the computer account password that the computers use to authenticate to the domain controllers in the domain.
You can use it to reset the password of the local computer.
You can use it to reset the password of the local computer.
This detection identifies a large-scale phishing campaign utilizing legitimate SharePoint Personal (OneDrive) infrastructure from external organizations to deliver malicious lure documents. By sending notifications via the official no-reply@sharepointonline.com address, the attackers bypass many reputation-based filters and exploit user trust in the Microsoft 365 ecosystem.
