WERE YOU AFFECTED?

Data Breach Lawsuits & Investigations

Every year, hundreds of millions of people are affected by data breaches that can leave them vulnerable to identity theft, credit damage, reputational harm and more.

Class action lawsuits remain one of the strongest ways to hold companies accountable for leaving consumers’, employees’ and patients’ private information unprotected. Indeed, some have resulted in multi-million-dollar settlements on behalf of those who – through no fault of their own – had their information stolen and, in the worst cases, even published on the dark web.

When a data breach lawsuit is successful, it can also require the company at fault to implement new security protocols to ensure the information it is entrusted with – medical, financial and otherwise – stays safe.

Got a data breach notice?

Scroll down to see the list of data breaches attorneys working with ClassAction.org are currently investigating. If you see one that looks familiar, click through to learn more about the breach and what you can do to potentially help get a class action lawsuit started.

And remember – don’t throw your notice away! It essentially serves as proof that you were affected by a specific security incident and can be vital if you choose to take legal action for the harm you suffered.
