What is a Brute Force Attack?
A Brute Force Attack is a method of systematically attempting multiple combinations of usernames and passwords until valid credentials are discovered. This attack exploits weak authentication mechanisms and poor password hygiene, often targeting exposed services such as VPN, Remote Desktop, or web applications.
Unlike targeted techniques such as Phishing or Social Engineering, brute force attacks rely on automation and scale. Attackers may also combine this approach with credential stuffing using data from previous breaches, increasing success rates against systems lacking Multi Factor Authentication (MFA).
What is a Brute Force Attack used for?
Brute force attacks are used to gain unauthorized access to systems, escalate privileges, and move laterally across networks. Once access is achieved, attackers may deploy Malware, establish Backdoors, or initiate broader campaigns such as Business Email Compromise (BEC).
To mitigate these attacks, organizations must enforce strong password policies, Access Control policies, implement MFA, and deploy tools such as SIEM and IDPS to detect abnormal login behavior. Rate limiting, account lockout policies, and Zero Trust architectures further reduce risk.
