Brute Force Attack
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.
Attack Simulation
PIN Cracker
Target: 4-Digit PIN (0000-9999)
0000
LOCKED
Attempts
0
Time
0.00s
Simulating ~60 attempts per second (browser limited). Real tools can do millions/sec.
Interactive: Click "Start Brute Force" to simulate a computer guessing a 4-digit PIN. Notice how fast it finds a simple numeric combination.
Time to Crack
The complexity of a password exponentially increases the time required to crack it.
4-digit PIN (0-9)Instantly
8 chars (a-z)~5 Hours
8 chars (a-z, 0-9, !@#)~39 Years
Prevention & Defense
Account Lockout PoliciesLock the account after a certain number (e.g., 5) of failed login attempts.
Rate LimitingSlow down the response time for each failed login to make brute forcing impractically slow.
Strong Password RequirementsEnforce long passwords with mixed characters to increase the search space.
