A brute-force attack is an automated attempt to gain access to a website or account by repeatedly trying passwords or other credentials. These attacks are common because login pages are easy to find and automated tools can make large numbers of attempts quickly.
How Brute-Force Attacks Work
Attackers may try common passwords, reused credentials from earlier data breaches, predictable username-and-password combinations, or large generated lists. A successful login can expose administrative tools, customer information, website content, or connected systems, depending on the compromised account’s permissions.
Warning Signs to Watch For
- Repeated failed logins from one or many addresses
- Unexpected password-reset messages or account-lockout notices
- New administrator accounts, plugins, redirects, or file changes
- Unusual traffic spikes or login attempts outside normal business patterns
Practical Ways to Reduce the Risk
No single setting stops every attack. A layered approach is more effective:
- Enable multi-factor authentication for administrative and other sensitive accounts.
- Use long, unique passwords and a reputable password manager rather than reusing credentials.
- Apply login throttling or temporary lockouts carefully so attackers cannot make unlimited attempts.
- Keep the website platform, themes, plugins, and server software supported and updated.
- Limit administrator privileges, remove unused accounts, and monitor login and file-change activity.
- Maintain tested backups that are separated from the live website.
Use Current Security Guidance
The OWASP Authentication Cheat Sheet discusses multi-factor authentication, login throttling, account lockout, and safe authentication responses. The current NIST Digital Identity Guidelines provide broader guidance on authentication and credential management. Security controls should be selected for the site’s actual risk, users, and operational needs.
What to Do After Suspicious Activity
If you suspect an account has been compromised, preserve relevant logs, change affected credentials from a trusted device, review administrator access and recent changes, and contact the hosting or security provider. Avoid deleting evidence before the incident is understood. For matters that may involve legal or investigative needs, counsel should determine the appropriate preservation and reporting steps.
