Understanding your Sotheby's data breach notification letter
If a Sotheby's letter arrived in your mailbox, here is what it means, why you received it, and the free steps you can take right now.
Why you received this letter
Sotheby's is a world-renowned auction house and luxury marketplace specializing in the sale of fine art, jewelry, and high-value collectibles. In the course of facilitating these transactions, the company collects and stores sensitive personal information, including government-issued identification, financial account details, and comprehensive contact records necessary for high-stakes bidding and authentication processes. This data breach was officially reported to the New Hampshire Attorney General in 2025, confirming that unauthorized parties may have accessed internal systems. If you have received a formal data breach notification letter from Sotheby's, it indicates that your personal information was likely contained within the affected files. We recommend reviewing the letter carefully to understand the specific scope of the exposure and the identity protection services being offered by the company.
What to do after the letter
Confirm the notice is genuine
A legitimate Sotheby's notice references the specific incident reported to the New Hampshire Attorney General and describes which categories of your information were involved. Compare the letter against the public filing before acting on any links or phone numbers it contains.
Keep the letter — it is your proof of connection
The notification letter is the document that ties your personal information to this incident. Keep the original and photograph it. If you later request a case review, this letter is the strongest evidence that you were among the affected individuals.
Protect your accounts and credit
Depending on what was exposed, consider a free credit freeze with all three bureaus, new passwords for reused credentials, and monitoring of financial statements. These steps are free and do not require you to wait for anyone's permission.
