Description

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 net accounts (/domain), Get-ADDefaultDomainPasswordPolicy, chage -l <username>, cat /etc/pam.d/common-password, and pwpolicy getaccountpolicies . Adversaries may also leverage a Network Device CLI on network devices to discover password policy information (e.g. show aaa, show aaa common-criteria policy all). Password policies can be discovered in cloud environments using available APIs such as GetAccountPasswordPolicy in AWS .
