Cybersecurity Knowledge Base

Understanding the threats detected by our systems.

SSH Brute Force

An automated attack where a script attempts to guess the password of a Secure Shell (SSH) server by trying thousands of combinations. This is a common method used by botnets to gain unauthorized access to servers.

Port Scanning

The practice of sending packets to specific ports on a host to identify open services. While used by administrators for auditing, it is often the first step in an attack to find vulnerabilities.

Botnet Activity

A network of compromised computers (bots) controlled by a third party. They are often used to coordinate DDoS attacks, send spam, or perform distributed brute-force attacks.
