Learn what a brute force attack is, how it works, and why hackers use it to crack passwords and encryption keys. Find out the types of brute force attacks, the tools they use, and the motives behind them, as well as how to prevent them.
- A brute force attack uses trial and error in an attempt to guess or crack an account password, user login credentials, and encryption keys.
- In the vast majority of cases, a brute force attack is illegal. It is only legal when an organization runs a penetration test against an applicatio...
- Brute force attacks are a fairly common method used by cyber criminals. They accounted for 5% of all data breaches in 2017, according to Verizon re...
- The longer and more complex a password is, the more difficult it is to crack. An eight-character password is widely considered to be crackable in a...
Jun 8, 2020 · A brute force attack is an attack where attackers follow a brute force approach to hack usernames and passwords. Hackers use trial and error methods to get the user account credentials and steal the information on the user accounts.

A brute force attack is uses a trial-and-error approach to systematically guess login info, credentials, and encryption keys. The attacker submits combinations of usernames and passwords until they finally guess correctly. Once successful, the actor can enter the system masquerading as the legitimate user and remain inside until they are detected. ...
Simple brute force attack
A simple brute force attack uses automation and scripts to guess passwords. Typical brute force attacks make a few hundred guesses every second. Simple passwords, such as those lacking a mix of upper- and lowercase letters and those using common expressions like ‘123456’ or ‘password,’ can be cracked in minutes. However, the potential exists to increase that speed by orders of magnitude. All the way back in 2012, a researcher used a computer cluster to guess up to350 billion passwords per sec...
Dictionary Attack
A dictionary attack tries combinations of common words and phrases. Originally, dictionary attacks used words from a dictionary as well as numbers, but today dictionary attacks also use passwords that have been leaked by earlier data breaches. These leaked passwords are available for sale on the dark web and can even be found for free on the regular web. Dictionary software is available that substitutes similar characters to create new guesses. For example, the software will replace a lowerca...
Credential Stuffing
Over the years, more than8.5 billionusernames and passwords have been leaked. These stolen credentials are sold between bad actors on the dark web and used in everything from spam to account takeovers. A credential stuffing attackuses these stolen login combinations across a multitude of sites. Credential stuffing works because people tend to re-use their login names and passwords repeatedly, so if a hacker gets access to a person’s account with an electric company, there is an excellent chan...
Attackers can use brute force attacks to: 1. steal sensitive data 2. spread malware 3. hijack systems for malicious purposes 4. make websites unavailable 5. profit from ads 6. reroute website traffic to commissioned ad sites 7. infect sites with spyware in order to collect data to sell to advertisers The level of technological skill required to lau...
Adversaries use automated tools to execute brute force attacks, and those lacking the skill to build their own can purchase them on the dark webin the form of malware kits. They can also purchase data such as leaked credentials that can be used as part of a credential stuffing or hybrid brute force attack. These lists may be offered as part of a pa...
Tools, many free, are available on the open internet that work against a wide variety of platforms and protocols. Here are just a few: 1. Aircrack-ng: Aircrack-ng is a brute force wifi password tool that is available for free. It comes with WEP/WPA/WPA2-PSK cracker and analysis tools to perform attacks on Wi-Fi 802.11 and can be used for any NIC th...
Use multifactor authentication
When users are required to offer more than one form of authentication, such as both a password and a fingerprint or a password and a one-time security token, a brute force attack is less likely to succeed.
Implement IT hygiene
Gain visibility into the use of credentials across the environment and require passwords to be changed regularly.
Set up policies that reject weak passwords
Longer passwords are not always better. What really helps is to require a mix of upper- and lowercase letters mixed with special characters. Educate users on best password practices, such as avoiding adding four numbers at the end and avoiding common numbers, such those beginning with 1 or 2. Provide a password management tool to prevent users from resorting to easily-remembered passwords and use a discovery tool that exposes default passwords on devices that haven’t been changed.
Learn what a brute force attack is, how it works, and why attackers use it. Explore the different types of brute force attacks, such as dictionary, credential stuffing, reverse, and hybrid, and the tools and motives behind them.
In cryptography, a brute-force attack consists of an attacker submitting many passwords or passphrases with the hope of eventually guessing correctly. The attacker systematically checks all possible passwords and passphrases until the correct one is found.
Learn what a brute force attack is, how it works, and how to test for it. See examples of tools and techniques for finding hidden content, directories, and authentication vulnerabilities.
May 28, 2024 · A brute force attack is a relatively old technique from threat actors and cyberattackers — but today it is widely used and remains highly effective. Attackers use brute force attacks to: Crack passwords. Decrypt encrypted data. Gain access to unauthorized systems, websites or networks.
What's a Brute Force Attack? A brute force attack uses trial-and-error to guess login info, encryption keys, or find a hidden web page. Hackers work through all possible combinations hoping to guess correctly.
