Have I Been Pwned treats this breach as sensitive: it does not reveal publicly whether a particular address is in it. Only the owner of an address can check, after verifying it.

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 to do if you had an account

  1. Turn on two-step sign-in. Enable two-factor authentication where the service offers it, preferably with an authenticator app or a passkey. A leaked password alone is then not enough to get in.
  2. Expect targeted phishing. Leaked contact details are used to write convincing fake messages that mention the breached company or your real name. Do not click links in unexpected emails or texts about this account; go to the site by typing its address.
  3. Watch for scam calls and SIM swaps. Be suspicious of calls and texts that claim to be from your bank or a courier. Ask your mobile operator for a port-out or SIM-change PIN if it offers one.
