Adversaries may attempt to access detailed information about the password policy used within an enterprise network or cloud environment. Password policies are a way to enforce complex passwords that are difficult to guess or crack through Brute Force. This information may help the adversary to create a list of common passwords and launch dictionary and/or brute force attacks which adheres to the policy (e.g. if the minimum password length should be 8, then not trying passwords such as 'pass123'; not checking for more than 3-4 passwords per account if the lockout is set to 6 as to not lock out accounts). Password policies can be set and discovered on Windows, Linux, and macOS systems via various command shell utilities such as <code>net accounts (/domain)</code>, <code>Get-ADDefaultDomainPasswordPolicy</code>, <code>chage -l <username></code>, <code>cat /etc/pam.d/common-password</code>, and <code>pwpolicy getaccountpolicies</code> (Citation: Superuser Linux Password Policies) (Citation: Jamf User Password Policies). Adversaries may also leverage a Network Device CLI on network devices to discover password policy information (e.g. <code>show aaa</code>, <code>show aaa common-criteria policy all</code>).(Citation: US-CERT-TA18-106A) Password policies can be discovered in cloud environments using available APIs such as <code>GetAccountPasswordPolicy</code> in AWS (Citation: AWS GetPasswordPolicy).
Chain: (1) IdP policy/read operations by a principal (e.g., Microsoft Entra/Graph requests to read password or authentication policies); (2) adjacent risky changes (role assignment, app consent) by same principal. Use IdP audit logs.
Chain: (1) cloud API calls that fetch tenant/organization password policy (e.g., AWS `GetAccountPasswordPolicy`, GCP/OCI equivalents or IAM settings reads); (2) within a short window, the same principal creates users, rotates creds, or changes auth settings. Use cloud audit logs.
Chain: (1) execution of `pwpolicy` or MDM/DirectoryService reads of account policies; (2) optional read of `/Library/Preferences/com.apple.loginwindow` or config profiles; (3) follow-on credential probing or lateral movement by same user/session. Use unified logs and process telemetry.
