Adversaries may use brute force techniques to gain access to accounts when passwords are unknown or when password hashes are obtained.[1] 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.[2] 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.

Offense vs defense T1110
Is defensive coverage keeping up with adversary use? Eight counts, each ranked against all 697 ATT&CK techniques. Attack sits left, defense right, so a shape leaning left means adversaries are better documented here than defenders are equipped. Hover any spoke for its percentile and the share of techniques that have more. The timeline below shows when each side arrived.

MITRE names one behaviour worth catching for this technique and breaks it into 5 analytics, one per platform. Each carries the log sources it needs and the fields you tune per environment.
Brute Force Authentication Failures with Multi-Platform Log Correlation
5 platforms
AN1275 · Windows
High volume of failed logon attempts followed by a successful one from a suspicious user, host, or timeframe
Log sources
The data this analytic draws on. You do not need every component — each one you already collect covers part of it. Each links to its ATT&CK record.
| Data component | Name | Channel |
|---|---|---|
| User Account AuthenticationDC0002 | WinEventLog:Security | EventCode=4776, 4625 |
Tunable fields
MITRE calls these the analytic’s mutable elements: the thresholds and filters you set for your own environment.
| Field | What you tune |
|---|---|
| TimeWindow | Adjustable window to correlate failed logons, e.g., 5-10 minutes |
| UserContext | Define scope of monitored users (e.g., service accounts, admins) |
| FailureThreshold | Count of failed logons before raising an alert (e.g., 10-15) |
AN1276 · Linux
Multiple authentication failures for valid or invalid users followed by success from same IP/user
Log sources
The data this analytic draws on. You do not need every component — each one you already collect covers part of it. Each links to its ATT&CK record.
| Data component | Name | Channel |
|---|---|---|
| User Account AuthenticationDC0002 | auditd:USER_LOGIN | USER_AUTH |
Tunable fields
MITRE calls these the analytic’s mutable elements: the thresholds and filters you set for your own environment.
| Field | What you tune |
|---|---|
| TimeWindow | Period of brute force activity correlation (e.g., 5 mins) |
| IPWhitelist | Exclude known monitoring IPs or jump boxes |
| LoginSource | Filter SSH vs. local logins |
AN1277 · Identity Provider
Password spraying or brute force attempts across user pool within short time intervals

MITRE calls these the analytic’s mutable elements: the thresholds and filters you set for your own environment.
| Field | What you tune |
|---|---|
| UsernameSprayThreshold | Max number of accounts targeted from a single IP |

AN1278 · macOS

Account Use PoliciesM1036
Set account lockout policies after a certain number of failed login attempts to prevent passwords from being guessed. Too strict a policy may create a denial of service condition and render environments un-usable, with all accounts used in the brute force being locked-out. Use conditional access policies to block logins from non-compliant devices or from outside defined organization IP ranges. Consider blocking risky authentication requests, such as those originating from anonymizing services/proxies.
Use multi-factor authentication. Where possible, also enable multi-factor authentication on externally facing services.
Password PoliciesM1027
Refer to NIST guidelines when creating password policies.
Proactively reset accounts that are known to be part of breached credentials either immediately, or after detecting bruteforce attempts.
