Brute force encryption and password cracking are dangerous tools in the wrong hands. Here's what cybersecurity pros need to know to protect enterprises against brute force and dictionary attacks. Speaking in laymen terms, a brute force attack typically is a hit-and-try attacking method. A set of predefined values is matched against data generated from attacking a target.

To find the of all that are of, a brute force algorithm would search through all positive integers, checking each one to see if it is a multiple of seven, whereas a more intelligent algorithm might simply the set of all positive integers by seven.

By trying every possible password combination, or using a dictionary of common passwords, a hacker can gain access to an organization's most valuable secrets.

It isn't just web applications that are at risk from brute force attacks—encrypted databases, password-protected documents, and other secure data can be stolen in a brute force attack, whether it's available online or downloaded to an attacker's computer. It's essential that cybersecurity professionals know the risks associated with brute force attacks. Read on to find out what you need to know about this classic form of cybersecurity attack, how safe you may (or may not) be, and how to defend your systems against brute force attacks. SEE: (Tech Pro Research) What is a brute force attack?

Brute force attacks involves repeated login attempts using every possible letter, number, and character combination to guess a password. An attacker using brute force is typically trying to guess one of three things: A user or an administrator password, a password hash key, or an encryption key. Guessing a short password can be relatively simple, but that isn't necessarily the case for longer password or encryption keys—the difficulty of brute force attacks grows exponentially the longer the password or key is. The most basic form of brute force attack is an, which is exactly what it sounds like: Trying every single possible password solution (i.e., lowercase letters, capital letters, numbers, and special characters) character by character until a solution is found. Other brute force methods attempt to narrow the field of possible passwords by using a dictionary of terms (which is covered in more detail below), a rainbow table of precomputed password hashes, or rules based on usernames or other characteristics known about the account being targeted.

To solve that problem attackers have turned to specialized hardware that looks a lot like a cryptocurrency mining rig. Brute-force attacks and are essentially the same thing: Brute force computing power is used to manually crack encryption.

That means the hardware needed to perform either with any degree of efficiency is the same—graphics processing units (GPUs) and application-specific integrated circuits (ASICs) designed for cryptocurrency use. GPUs and cryptocurrency ASICs are designed to handle large loads of repetitive tasks, which is exactly what a brute force attacker needs. That doesn't mean every hacker who is attempting a brute force attack uses one, but those who are serious about stealing your data definitely do. Brute force attacks would be impossible for an individual to try manually, which is why a number of popular programs have appeared over the years that, while having legitimate purposes, can easily be turned to illicit use.

Exhaustive key searches are the solution to cracking any kind of cryptography, but they can take a very long time.

When an attacker has a high degree of confidence that the password they're trying to crack consists of certain words, phrases, or number and letter combinations, it can be much quicker to compile a dictionary of possible combinations and use that instead. SEE: Dictionary attacks can use an actual dictionary, but it's more likely for them to contain a shorter list of words that an attacker thinks are likely to be successful. Commonly used password lists, popular names, pet names, movie or television characters, and other words can all be part of a dictionary list. That's not to say there isn't an element of randomness to dictionary attacks—they typically account for common passwords that append a number or special character on the end of a word, or substitute a letter for a number, in order to guess any number of variations on a word or phrase.

When thinking of a brute force or a dictionary attack, one may jump to the conclusion that it's a problem exclusive to web applications or other secure online locations, but that's hardly the case.
