That’s why attackers are utilizing an attack called “password spraying” as an alternative to brute-forcing. This makes brute-forcing too time-consuming. To avoid account lockouts, attackers will have to space out their password guesses. This means that traditional brute-force attacks are no longer feasible for a majority of applications. The majority of web applications now implements account lockout policies. If the application detects that an account has had a few failed login attempts in a short timeframe, the application will block the account from further logins. The application will often also notify the user of the failed login attempts or alert the system admins. She tries to log into the service with the username “Vickie” and different passwords until she finds the correct one.īut modern applications are getting smarter.
Then, the attacker uses a script to rapidly fire off login attempts to the service. She can either use a dictionary of common passwords she found online, or a list of likely passwords generated based on her knowledge of the user. The attacker will first generate a password list to use.
Let’s say an attacker is trying to hack the account of the user “Vickie”. Have you heard of a password brute-force attack? A brute-force attack is when attackers try to hack into a single account by guessing its password. And how attackers bypass account lockout when brute-forcing passwords.
