Key notes
The major difference between password spray and credential stuffing is the requirement needed to carry out the attack. They are both brute-force attacks used by bad actors to illegally gain access to user accounts.
While this might sound scary at first, they still depend on mistakes from your end. In this password spray vs credential stuffing guide, we will show how to prevent these attacks and the differences between them.
What is password spray?
A password spray is a form of brute-force attack where the wrongdoer tries some random commonly used password on different valid usernames. That means that the attacker does not have any legitimate information.
Instead, they spray some of the common and easy-to-remember passwords an average user uses on many valid usernames. Some of these weak passwords include password, 123456, 123abc, and 111111 etc.
They repeat this procedure with different common passwords till they eventually breach one of the accounts.
What is credential stuffing?
Unlike password spray, in credential stuffing, the attacker gets access to the login credentials for a user’s account. This usually happens via online leaks; maybe the website’s database where you have an account got compromised.
With the password from the single account, the bad actor tries to get access to other online accounts held by the same user. If the password does not, the hacker tries different variations of the same password.
For example, a hacker might get access to a user’s Facebook username, email, and password. He then will try the password to get into the person’s Twitter or Gmail account. If this does not work, they use a variation of the password instead.
What is the difference between password spraying and credential stuffing?
1. Objective of attack
The major objective of these two types of attacks is to illegally get access to users’ accounts. However, for credential stuffing, the objective is to use a leaked user credential for one account to get access to multiple accounts held by the same user.
Password spraying, on the other hand, requires the bad actor to have a list of common passwords that will be sprayed on different valid usernames.
2. Requirement
The requirement for a credential stuffing attack is a leaked online credential base to work with. They usually get this through online leaks or by hacking an organization’s database.
While password spraying requires no leaked data. Just a random list of valid usernames, which is usually an email address and commonly used and simple passwords.
3. Mode of operation
While credential stuffing can be done manually, hackers use botnets. They feed the available data to the bots that start making different variations to get access to other accounts.
This form of attack works because most internet users do not keepunique passwords for different accounts. Instead, they use the same password over and over or a variation of it.
Attackers also use botnets for password spraying. The bots work with valid usernames and match them to commonly used passwords till they get a valid credential for an account.
This form of attack is sometimes successful because an average internet user has tens of accounts that require passwords. So, most people prefer to use these weak and so-called easy-to-remember passwords. This makes it easy for hackers to get access to their accounts.
How can I prevent credential stuffing and password spraying?
Below are some of the things an organization and individual can do to prevent these brute-force attacks:
