Is the Sotheby's data breach letter legit or a scam?

A notice from Sotheby's in the mail matches the breach Sotheby's reported to the New Hampshire Attorney General on October 15, 2025. Check that the company name and dates in your letter match that filing. A real notice of data security incident won't ask for your password, Social Security number or a payment — if it does, contact Sotheby's through a phone number or website you find yourself.

Can I sue Sotheby's over the data breach?

It depends on what was exposed, the law in New Hampshire and your own state, and whether you've been harmed. Most people take part through a class action rather than suing alone. Keep your notification letter — it's the proof that connects you to the breach.

How much could a Sotheby's data breach settlement or claim be worth?

There is no set amount, and no Sotheby's settlement is confirmed here. In past data breach settlements, payments depended on what data was exposed and on documented losses — fraud, out-of-pocket costs and time spent dealing with the breach. Keep receipts and records; they're what damages claims are built on.

Do I need a Sotheby's data breach lawyer or attorney?

An attorney can read your notice and tell you whether a claim makes sense. A case review here is free, and data breach cases are usually handled on contingency, so there is no upfront cost.
