When we say a password was compromised in a data breach, it means that the password was exposed during a security incident in which hackers accessed a database of usernames and passwords. These stolen passwords often end up on the dark web, where cybercriminals can use them to try to break into other accounts.
Does it mean that my account is compromised and leaked?
Not necessarily. Just because a password was compromised doesn’t mean your specific account was involved in a data breach. The password might have been leaked as part of someone else’s account, but if you’re using the same password, your account could still be at risk.
Why is it dangerous to use a compromised password?
Using a compromised password is risky because hackers know that people often reuse passwords across multiple accounts. Here’s how they can use this information to hack into accounts:
- Credential stuffing: Hackers take the compromised password and try it on different websites, hoping that someone reused it. If they get a match, they can access your account.
- Phishing attacks: Knowing that a password has been compromised, hackers might target you with phishing attacks, pretending to be from a trusted service to get more information.
- Account takeover: If a hacker gains access to one of your accounts using a compromised password, they could potentially lock you out, steal personal information, or even use the account to scam others.
What should you do?
If you find out that a password you’re using has been compromised, the best thing to do is change it immediately. Make sure to use a unique password that you haven’t used before. Here are some tips for creating a strong password:
- Use a mix of characters: Combine uppercase letters, lowercase letters, numbers, and special characters.
- Make it long: Aim for at least 12 characters.
- Avoid common words or phrases: Don’t use easily guessable information like your name, birthday, or simple sequences like "123456" or "password."
Consider using a password manager to help you create and store strong, unique passwords for all your accounts. This way, even if one password is compromised, the rest of your accounts will remain secure.
