Simple brute force attack-uses a systematic approach to ‘guess’ that doesn’t rely on outside logic.Bots systematically attack websites and try these lists of credentials, and notify the attacker when they gain access. Attackers have lists of commonly used credentials, or real user credentials, obtained via security breaches or the dark web. While some attackers still perform brute force attacks manually, today almost all brute force attacks today are performed by bots. Attacker motivation may include stealing information, infecting sites with malware, or disrupting service.
In other cases, attackers try to access web applications by searching for the right session ID. These tools try out numerous password combinations to bypass authentication processes. Some attackers use applications and scripts as brute force tools. Brute force is a simple attack method and has a high success rate. A brute force attack involves ‘guessing’ username and passwords to gain unauthorized access to a system. A brute force attack is a popular cracking method: by some accounts, brute force attacks accounted for five percent of confirmed security breaches.
