What happened?
In July 2016, a tweet was posted with a link to an alleged data breach of BlueSnap, a global payment gateway and merchant account provider . The data contained 324k payment records across 105k unique email addresses and included personal attributes such as name, home address and phone number. The data was verified with multiple Have I Been Pwned subscribers who confirmed it also contained valid transactions, partial credit card numbers, expiry dates and CVVs. A downstream consumer of BlueSnap services known as Regpack was subsequently identified as the source of the data after they identified human error had left the transactions exposed on a publicly facing server. A full investigation of the data and statement by Regpack is detailed in the post titled Someone just lost 324k payment records, complete with CVVs .

What should you do?
Compare the organization, dates, and information categories with any notice you received. Use contact details you independently confirm.
Review your credit reports and consider a free credit freeze if identity information could support new-account fraud.
Check statements for unfamiliar activity and contact the card issuer or financial institution through an independently verified channel.
Treat unexpected breach follow-ups with caution. Do not use links or phone numbers in a suspicious message; contact the organization directly.
Choose actions that match the information involved. If you find signs that someone is using your identity, the Federal Trade Commission provides a personal recovery plan at IdentityTheft.gov.
