DETECTION OVERVIEW

SMB Brute Force

Risk Factors

Brute force attacks are low cost and relatively easy to do, so they are common. If an attacker gains entry to your network through a poorly-secured workstation, it can lead to further exploits of higher-value assets. It is worth your time to secure workstations by adding strict password requirements.

The system might change the risk score for this detection.

Attack Background

Brute force attacks can occur manually through trial and error or with password cracking tools. The attacker makes repeated attempts to try all possible variations of a password. There are variations of a brute force attack that include a dictionary attack, where the attacker tests a large number of common passwords. Stealthy brute force attacks can also occur through a small number of attempts across a large number of hosts.

Mitigation Options

Add strict password requirements, such as complex passwords, limit login attempts, and lock out users who repeatedly submit invalid passwords

Add multi-factor authentication

MITRE ATT&CK ID
