This rule detects the initialization of an AWS CloudShell environment or session where Multi-Factor Authentication (MFA) was not explicitly recorded in the event data. Unauthorized access to CloudShell can provide an adversary with a command-line interface to interact with AWS APIs, potentially facilitating further malicious activities.
Detects potential privilege escalation where an identity with iam:PassRole permissions deploys or updates compute resources (CloudFormation, EC2, or Lambda) to assume a more privileged IAM role than the user currently holds.
Detects the use of sts:AssumeRole or sts:GetFederationToken to request temporary security credentials in a different AWS account than the one initiating the request. This can indicate cross-account privilege escalation or lateral movement using identity federation or assumed roles.

Detects the use of sts:AssumeRole or sts:GetFederationToken to request temporary security credentials in a different AWS account than the one initiating the request. This can indicate cross-account privilege escalation or lateral movement using identity federation or assumed roles.
Detects the use of AWS CloudShell to execute commands that download or install external files (e.g., using curl, wget, pip, or git), excluding those originating from known approved sources such as AWS-owned domains or standard package registries. This behavior may indicate an adversary attempting to download offensive tooling or backdoors into the cloud environment.
Detects 'PutBucketPolicy' API calls in AWS CloudTrail where the policy is modified to grant 'Allow' access to a wildcard ('*') or anonymous principal, without including restrictive conditional requirements such as VPC endpoints or organizational ID constraints. This behavior is a common precursor to data exfiltration from misconfigured S3 buckets.
Detects modifications to AWS EC2 snapshot or AMI attributes that grant cross-account permissions, including making them publicly accessible. This activity may indicate an attempt to exfiltrate volume data, such as credentials, configuration, or database contents, to an external AWS account.
Detects unauthorized attempts to disable, suppress, or modify security monitoring services in AWS, including GuardDuty, Security Hub, and AWS Config. This rule monitors for API calls that effectively reduce cloud visibility or detection capabilities, explicitly excluding actions performed by authorized security-engineering roles.
Detects the creation of recurring EventBridge rules or EventBridge Scheduler schedules configured with cron or rate expressions that trigger Lambda functions or SSM automation documents. This activity is a common method for cloud-native persistence, allowing for durable, recurring execution of malicious code that persists across credential rotations or resource deletions, provided the actor is not a recognized platform-engineering entity.
