What happened
In September 2026, Swiss medical device company Medela was the target of a ShinyHunters "pay or leak" extortion campaign. The data allegedly obtained in the breach was later published publicly and included 424k unique email addresses belonging predominantly to healthcare professionals, Medela staff and leads. The exposed data consisted primarily of corporate contact information, including names, physical addresses and phone numbers, with some records also containing associated support tickets.

What was exposed
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.
Job titles: Your role or position, such as accounts payable officer, nurse or IT administrator, recorded by professional networks, business software, event registrations and marketing lists.
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.
Phone numbers: Your mobile or landline number, collected at signup for contact, delivery updates, marketing and two-factor codes.
Physical addresses: Your residential, postal, billing or delivery address, stored by retailers, utilities, banks, government services and almost any company that sends you something.
Salutations: The title used before your name, such as Mr, Mrs, Ms, Mx, Dr or Rev, stored so letters and emails can address you formally.
