Brute Force Attack

A brute force attack is a trial-and-error method used to decode a password or encrypted data. Attackers employ brute force most often for cracking passwords, but they also use this method to obtain encryption keys, API keys, and SSH logins. Threat actors will systematically try every possible combination of letters, numbers, and symbols until they guess correctly. These attacks are often opportunistic without reconnaissance on the intended target. While a simple method, brute force attacks remain effective against weak security. 

To protect against brute force attacks, organizations should implement complex, strong passwords combined with security measures such as CAPTCHA, account lockout policies, and the use of multi-factor authentication (MFA). These steps significantly reduce the risk of a successful brute force attack by increasing the complexity and time required to break into an account.
