What does it mean if personal information was found on the dark web?

Identity thieves use the Dark Web to buy and sell personal information. If you have ever been a victim of a data breach, the Dark Web is a place where your sensitive information might live. If your information is there, criminals can potentially use it to commit fraud. There have been numerous hacks in recent years that have allowed the details of vast numbers of people to be compromised. What action to take, if any, depends on the type of personal information involved.

Probably nothing you can do, except to change passwords on whatever account(s) were compromised.

Your name/SSN/other stuff was likely bought and sold a dozen times from one broker to another. You’ll never eradicate all of the groups who have control of your data.

Get annual credit reports, keep an eye on financial transactions, and play defense. That’s really about all you can do.
