Метод перебора

Adversaries may use brute force techniques to gain access to accounts when passwords are unknown or when password hashes are obtained. Without knowledge of the password for an account or set of accounts, an adversary may systematically guess the password using a repetitive or iterative mechanism. Brute forcing passwords can take place via interaction with a service that will check the validity of those credentials or offline against previously acquired credential data, such as password hashes. Brute forcing credentials may take place at various points during a breach. For example, adversaries may attempt to brute force access to Valid Accounts within a victim environment leveraging knowledge gathered from other post-compromise behaviors such as OS Credential Dumping, Account Discovery, or Password Policy Discovery. Adversaries may also combine brute forcing activity with behaviors such as External Remote Services as part of Initial Access.

User Account Management

Manage the creation, modification, use, and permissions associated to user accounts.

Account Use Policies

Configure features related to account use like login attempt lockouts, specific login times, etc.

Brute Force Mitigation

Set account lockout policies after a certain number of failed login attempts to prevent passwords from being guessed. Too strict a policy can create a denial of service condition and render environments un-usable, with all accounts being locked-out permanently. Use multifactor authentication. Follow best practices for mitigating access to Valid Accounts Refer to NIST guidelines when creating passwords.(Citation: NIST 800-63-3) Where possible, also enable multi factor authentication on external facing services.

Multi-factor Authentication

Use two or more pieces of evidence to authenticate to a system; such as username and password in addition to a token from a physical smart card or token generator.

Password Policies

Set and enforce secure password policies for accounts.


Monitor authentication logs for system and application login failures of Valid Accounts. If authentication failures are high, then there may be a brute force attempt to gain access to a system using legitimate credentials. Also monitor for many failed authentication attempts across various accounts that may result from password spraying attempts. It is difficult to detect when hashes are cracked, since this is generally done outside the scope of the target network.
