Service: signin

Description

Catch-all entry for AWS Sign-In rules that match the service but not a specific eventName.

ConsoleLogin

Service: signin

Description

Records an authentication attempt to the AWS Management Console, including whether it succeeded or failed.

CloudTrail management event, logged by default. Logged as eventType AwsConsoleSignIn (not AwsApiCall); requestParameters is null. Console sign-in events for the global endpoint are recorded in us-east-1. A failed sign-in does not set errorCode: it sets responseElements.ConsoleLogin = Failure and errorMessage = Failed authentication, so query those fields for failures.

AWS ConsoleLogin Failed Authentication source medium: Detects failed AWS console login attempts due to authentication failures. Monitoring these events is crucial for identifying potential brute-force attacks or unauthorized access attempts to AWS accounts.T1110
AWS Successful Console Login Without MFA source medium: Detects successful AWS console logins that were performed without Multi-Factor Authentication (MFA). This alert can be used to identify potential unauthorized access attempts, as logging in without MFA can indicate compromised credentials or misconfigured security settings.T1078, T1078.004

AWS Management Console Brute Force of Root User Identity source high: Identifies a high number of failed authentication attempts to the AWS management console for the Root user identity. An adversary may attempt to brute force the password for the Root user identity, as it has complete access to all services and resources for the AWS account.T1110, T1110.001
AWS IAM User Console Login from Multiple Geolocations source medium: Identifies an IAM user that successfully signs in to the AWS Management Console from two or more distinct countries within a short window. A single user authenticating from multiple geographic locations in a brief period is physically implausible and indicates that the account's credentials or console session are being used from more than one place at once. This is a hallmark of adversary-in-the-middle (AiTM) phishing and session theft, where the legitimate user signs in from their location while the attacker replays the captured session or credentials from their own infrastructure. Because the attacker logs in from a different network, the divergent sign-in geolocations are the detectable signal even when MFA appears satisfied (AiTM relays the live MFA challenge). This is the CloudTrail-native analog of identity-provider impossible-travel sign-in detections.T1078, T1078.004, T1539
AWS Management Console Root Login source medium: Identifies a successful login to the AWS Management Console by the Root user.T1078, T1078.004

AWSCloudTrail - Login to AWS Management Console without MFA source low: Identifies successful AWS Management Console sign-ins where CloudTrail records a ConsoleLogin event without multi-factor authentication. The rule looks for logins where MFAUsed is not Yes and the console response is not Failure, which can indicate credential misuse or weak account protection.T1078
AWSCloudTrail - NRT Login to AWS Management Console without MFA source low: Multi-Factor Authentication (MFA) helps you to prevent credential compromise. This alert identifies logins to the AWS Management Console without MFA. You can limit this detection to trigger for administrative accounts if you do not have MFA enabled on all accounts. This is done by looking at the eventName ConsoleLogin and if the AdditionalEventData field indicates MFA was NOT used and the ResponseElements field indicates NOT a Failure. Thereby indicating that a non-MFA login was successful.T1078

Retrieves a sign-in token used to grant console access to a federated user via the AWS federation endpoint.

CloudTrail management event, logged by default. Logged as eventType AwsConsoleSignIn (not AwsApiCall). The event records the federation endpoint call that issues a sign-in token for constructing a console URL.

AWS Console GetSigninToken Potential Abuse source medium: Detects potentially suspicious events involving "GetSigninToken". An adversary using the "aws_consoler" tool can leverage this console API to create temporary federated credential that help obfuscate which AWS credential is compromised (the original access key) and enables the adversary to pivot from the AWS CLI to console sessions without the need for MFA using the new access key issued in this request.T1021, T1021.007, T1550, T1550.001
Attempt To Get Signin Token source medium: Generate a SigninToken that can be used to login to the the AWS Management Console. Attackers might access via a Federated identity (such as AWS SSO) to the Management Console.T1078, T1078.004
Get Signin Token source high: Generate a SigninToken that can be used to login to the the AWS Management Console. Attackers might access via a Federated identity (such as AWS SSO) to the Management Console.T1078, T1078.004

Elastic #

AWS Sign-In Token Created source low: Captures requests to the AWS federation endpoint (signin.amazonaws.com) for GetSigninToken. This API exchanges existing temporary AWS credentials (e.g., from STS GetFederationToken or AssumeRole) for a short-lived sign-in token that is embedded in a one-click URL to the AWS Management Console. It is commonly used by custom federation tools and automation to pivot from programmatic access to a browser session. This is a building block rule meant to be used for correlation with other rules to detect suspicious activity.T1078, T1078.004, T1550, T1550.001
AWS EC2 Instance Console Login via Assumed Role source high: Detects successful AWS Management Console or federation login activity performed using an EC2 instance’s assumed role credentials. EC2 instances typically use temporary credentials to make API calls, not to authenticate interactively via the console. A successful "ConsoleLogin" or "GetSigninToken" event using a session pattern that includes "i-" (the EC2 instance ID) is highly anomalous and may indicate that an adversary obtained the instance’s temporary credentials from the instance metadata service (IMDS) and used them to access the console. Such activity can enable lateral movement, privilege escalation, or persistence within the AWS account.T1021, T1021.007, T1078, T1078.004, T1550, T1550.001↳ also matches ConsoleLogin

Panther #

AWS Console GetSigninToken Potential Abuse source medium: Detects GetSigninToken calls from non-SSO user agents. An adversary can use tools like aws_consoler to convert compromised CLI credentials into a federated console session, bypassing MFA requirements and obscuring the original access key. The GetSigninToken API creates temporary console access from STS temporary credentials.T1021.007, T1550.001

AWS Sign-In Root Password Recovery Requested source high: Identifies a password recovery request for the AWS account root user.

UserAuthentication

Service: signin

Description

UserAuthentication recorded by CloudTrail for AWS Sign-In. Observed in real CloudTrail; no AWS SDK operation model documents it, so no description is available from the SDK.

Example CloudTrail Event #

This is a projected export row, not a complete CloudTrail record: it shows only the envelope columns a SIEM export retained. The export never carried userIdentity, requestParameters, responseElements, sourceIPAddress, recipientAccountId, eventCategory, so their absence here says nothing about the real event. Account identifiers, ARNs and endpoint hostnames in eventID, requestID, resources, tlsDetails, userAgent are replaced with the placeholders AWS uses in its own documentation, so those values are structurally real but not the originals. errorMessage is withheld: it is free-form prose that names customer resources, which no substitution rule can find reliably. eventTime is withheld because the export renders it in the exporting system's local timezone rather than the UTC a CloudTrail record carries.
