What is Brute Force Attack?

Hi friends, If you don't know about cracking data using Brute Force attack, this article will help you to gain much knowledge about the Brute Force attack.

What is Brute Force attack?

Brute force attack is one of the password cracking method. In this method we are trying every possible code, combination, or password by comparing different combination of characters (all possible keys) until you find the right one.

Let us assume the password length is 3. We have characters set (abcdefghijklmnopqrstuvwxyz0123456789) excluding the special characters.

The Number of Permutation takes to crack the password: -

For first character: -

Upper case letters(26 )+Lower Case Letters(26)+10 Numbers =62

Likewise for second and third character we have 62 different ways.
So the total permutation to produce different keys is =62*62*62=238328 ways.

If you include the special characters in character set, then the permutation to crack the password will increase.

If the password length is small, then it will be cracked in small amount of time. This method will take too longer time to crack lengthy passwords. It can take several hours, days, months, years.

The time depending upon the two factors: -

• Password Length
• Upper case and lower case letter combinations.

The difficulty of a brute force attack depends on several factors, such as: -

• How long can the key be?
• How many possible values can each component of the key have?
• How long will it take to attempt each key?
• Is there a mechanism which will lock the attacker out after a number of failed attempts?

Increasing Security Against a Brute Force Attack: -

• Increasing the length of the PIN
• Allowing the PIN to contain characters other than numbers, such as * or #
• Imposing a 30 second delay between failed authentication attempts
• Locking the account after 5 failed authentication attempts

Conclusion: -

For Hackers: -

Hope you understand about brute force attack, also the drawback of this method. You can take advantage if the password is simple and small in length.

For Security needers: -
