What happened
In March 2021, the Stripe account of the now-defunct WeLeakInfo service was taken over by "pompompurin" after acquiring an expired domain name with an email address used to manage the account. Access to Stripe then exposed almost 12k unique email addresses from customers who'd made credit card payments in order to obtain breached data hosted by WeLeakInfo. The data was subsequently leaked publicly and also included names, payment histories, IP addresses, billing addresses, partial credit card data and the organisation making the purchase.

What was exposed
Browser user agent details: A short text string your browser sends to every website, naming the browser, its version, the operating system and often the device type, for example Chrome on Windows or Safari on an iPhone.
Email addresses: The email address you used to register or log in. It is the most common field in breaches because it doubles as your username on most sites.
Employers: The name of the company or organisation you work for, collected by professional networks, job sites, insurers, lenders and many signup forms.
IP addresses: The network addresses your devices used when you signed up, logged in or posted, recorded by almost every website in its access logs.
Names: Your first name, surname and sometimes middle name or initials, as you gave them when you signed up. It appears in almost every breach because nearly every account asks for it.
Partial credit card data: Fragments of a payment card rather than the full number, typically the first six or last four digits, the card brand, the expiry date or the cardholder name.
Physical addresses: Your residential, postal, billing or delivery address, stored by retailers, utilities, banks, government services and almost any company that sends you something.
Purchases: Records of items or services you bought, often with order numbers, prices, dates, delivery addresses and the store or seller involved.
