[Cheat Sheet] IAM Enumeration CLI Commands

Here’s a list of commonly used or helpful AWS IAM enumeration commands that will be very useful for this course:

# IAM Enumeration CLI commands
## Retrieves general account information about including IAM users, groups, 
## roles, and policies, and their relationships to one another. 
## These are meant to be non-destructive enumeration commands. They only retrieve information. They do not modify resources.
## Official AWS IAM CLI documentation: https://awscli.amazonaws.com/v2/documentation/api/latest/reference/iam/index.html

# The "whoami" in AWS
aws sts get-caller-identity # Returns details about the IAM user or role whose credentials are used to call the operation. While not an IAM command (it's an STS command), this is often the first command that gets used for IAM enumeration which is why it's included here. 
# No policy can deny issuing this command since it gives the same information when access is denied. More on that here: https://awscli.amazonaws.com/v2/documentation/api/latest/reference/sts/get-caller-identity.html

# General IAM account information
aws iam get-account-authorization-details # Gives a snapshot of the configuration of IAM permissions (users, groups, roles, and  policies) and their relationships in your account.

# User enumeration
aws iam list-users
aws iam list-service-specific-credentials # Get service-specific credentials associated with the IAM user
aws iam get-user --user-name <username> # Get metadata of user. Includes permissions boundaries!
aws iam list-access-keys [--user-name <value>] # List existing access keys for a specific user (your current user being the default if no value is specified)
aws iam list-user-policies --user-name <username> # Get inline policies for a user
aws iam get-user-policy --user-name <username> --policy-name <policyname> # Get details about an inline policy
aws iam list-attached-user-policies --user-name <username> # Get attached (managed) policies (instead of inline policies). These can be either AWS-managed or Customer-managed policies
aws iam get-login-profile --user-name # Checks to see if the user has a login profile (password to log into the AWS Console). Returns the UserName and CreatedDate, which reflects the creation date of the password

# Groups Enumeration 
aws iam list-groups # Get groups in account
aws iam list-groups-for-user --user-name <username> # Get groups related to a user
aws iam get-group --group-name <name> # Get a group's details
aws iam list-group-policies --group-name <username> # Get inline policies of a group
aws iam get-group-policy --group-name <username> --policy-name <policyname> # Get inline policy details
aws iam list-attached-group-policies --group-name <name> # Get attached (managed) policies for a group (instead of inline policies). These can be either AWS-managed or Customer-managed policies

# Enumerate roles
aws iam list-roles # Get roles in the AWS account
aws iam get-role --role-name <role-name> # Get details about a specific role
aws iam list-role-policies --role-name <name> # Get inline policies of a role
aws iam get-role-policy --role-name <name> --policy-name <name> # Get inline policy details
aws iam list-attached-role-policies --role-name <role-name> # Get attached (managed) policies for a role (instead of inline policies). These can be either AWS-managed or Customer-managed policies

# Enumerate policies
aws iam list-policies [--only-attached] [--scope Local] # List policies
# [--only-attached] is optional and will list policies only if they're attached to an IAM user/group/role
# [--scope local] is optional and will only list policies that are Customer-managed, not AWS-managed. --scope AWS would be the opposite
aws iam list-policies-granting-service-access --arn <identity> --service-namespaces <svc> # Get list of policies that a user/group/role can use to access a specific service
# Example: aws iam list-policies-granting-service-access --arn arn:aws:iam::123456789012:user/UserName --service-namespaces eks
aws iam get-policy --policy-arn <policy_arn> # Get details for a specific policy
aws iam list-policy-versions --policy-arn <arn> # Returns information about policy versions for a specific managed policy, including which one is the current default version
aws iam get-policy-version --policy-arn <arn:aws:iam::123456789012:policy/example-policy> --version-id <v1 or v2 or ...> # Get details for a specific policy version since policies can have multiple versions
aws iam list-entities-for-policy --policy-arn <value> # Lists all the IAM users/groups/roles that the managed policy is attached to

# MFA
aws iam list-mfa-devices [--user-name <username>]  # Get list of all MFA devices for a specific user. If no user is provided, AWS auto determines the user based on the access key ID
aws iam list-virtual-mfa-devices [--assignment-status <value>] # Get list of all MFA devices in the AWS account
# Can use optional --assignment-status to filter by Assigned, Unassigned, or Any (the default)Code language: PHP (php)
