What is password spraying?
Password spraying is a type of brute-force attack(new oman phone number data window)where a cybercriminal tries one password on multiple usernames or email addresses, then tries another password, and continues this process. It takes a different approach from traditional brute-force attacks that test multiple passwords against a single username or email address.
The goal of a password spraying attack is to find a weak security link without drawing attention to itself. It does so by balancing efficiency and stealth: selecting likely passwords and using automated tools to test them while avoiding rapid, repeated login attempts that could trigger security alerts.
