This rule detects when a specific Okta actor has multiple device token hashes and multiple source IPs for a single Okta session. This may indicate an authenticated session has been hijacked or replayed from a different device and network. Adversaries may steal session cookies or tokens to gain unauthorized access to Okta admin console, applications, tenants, or other resources.

Read More

Detects potential Adversary-in-the-Middle (AiTM) session cookie replay attacks against Okta. This rule identifies when an Okta session is used from multiple IP addresses or with suspicious non-browser user agents after initial authentication. AiTM attacks capture session cookies via phishing proxies (e.g., Evilginx, Modlishka) and replay them from attacker infrastructure, bypassing MFA. The detection correlates session start events with subsequent policy evaluations or SSO attempts that occur from different IPs or programmatic user agents.

Read More

Correlates the first occurrence of an Okta user session started via a proxy with subsequent Okta security alerts for the same user. Attackers frequently use proxy infrastructure (VPNs, Tor, residential proxies) to mask their origin when using stolen credentials, and their post-authentication activity often triggers additional detection rules.

Read More

Detects when Okta FastPass prevents a user from authenticating to a phishing website.

Read More

Identifies when a single Okta device token hash (dt_hash) is associated with multiple operating system types. This is highly anomalous because a device token is tied to a specific device and its operating system. This alert strongly indicates that an attacker has stolen a device token and is using it to impersonate a legitimate user from a different machine.

Read More

Detects sign-in events where authentication is carried out via a third-party Identity Provider (IdP) that has not been seen before. Adversaries may add an unauthorized IdP to an Okta tenant to gain persistent access. This rule uses New Terms detection to only alert when a previously unseen IdP is used for authentication, reducing noise from legitimate federated identity providers while highlighting potentially rogue IdP additions.

Read More

Correlates Okta credential attack alerts with subsequent successful authentication for the same user account, identifying potential compromise following brute force, password spray, or credential stuffing attempts.

Okta ThreatInsight is a feature that provides valuable debug data regarding authentication and authorization processes, which is logged in the system. Within this data, there is a specific field called threat_suspected, which represents Okta's internal evaluation of the authentication or authorization workflow. When this field is set to True, it suggests the presence of potential credential access techniques, such as password-spraying, brute-forcing, replay attacks, and other similar threats.

Read More

Identifies when an administrator role is assigned to an Okta user or group. Adversaries may assign administrator privileges to compromised accounts to establish persistence, escalate privileges, and maintain long-term access to the environment. This detection monitors for both user-level and group-level administrator privilege grants, which can be used to bypass security controls and perform unauthorized administrative actions.

Read More

A user has initiated a session impersonation granting them access to the environment with the permissions of the user they are impersonating. This would likely indicate Okta administrative access and should only ever occur if requested and expected.

Read More

Detects successful single sign-on (SSO) events to Okta applications from an unrecognized or "unknown" client device, as identified by the user-agent string. This activity may be indicative of exploitation of a vulnerability in Okta's Classic Engine, which could allow an attacker to bypass application-specific sign-on policies, such as device or network restrictions. The vulnerability potentially enables unauthorized access to applications using only valid, stolen credentials, without requiring additional authentication factors.

Read More

Detects when a user reports suspicious activity for their Okta account. These events should be investigated, as they can help security teams identify when an adversary is attempting to gain access to their network.

Read More

Identifies unauthorized access attempts to Okta applications.

Read More

Identifies a failed OAuth 2.0 token grant attempt for a public client app using client credentials. This event is generated when a public client app attempts to exchange a client credentials grant for an OAuth 2.0 access token, but the request is denied due to the lack of required scopes. This could indicate compromised client credentials in which an adversary is attempting to obtain an access token for unauthorized scopes. This is a New Terms rule where the okta.actor.display_name field value has not been seen in the last 14 days regarding this event.
