If your social security number is on the dark web, it doesn’t necessarily mean people are using it for fraud, but it is possible. Criminals can use your SSN and personal details to commit identity theft and open new financial accounts in your name.  To prevent this, freeze all your credit reports and inform the relevant authorities about the issue. You can also sign up for a credit or identity theft monitoring service. Unfortunately, once your information is leaked on the dark web, it’s impossible to remove it completely.
