Krys Group
CriticalConfirmedRetail
An actor using the alias "Syrv4x" published two files attributed to Krys Group, a French opticians' and hearing-aid cooperative, for free on a cybercrime forum on September 29, 2026. Samples reviewed by several specialist outlets show names, dates of birth, and optical appointment or session details, with email, phone, and postal address fields present but not consistently filled in. The number of people affected is reported differently across sources (roughly 8,400 to 9,500), and how the data was obtained is not yet known.
Combining an identity, a date of birth, and an appointment history could facilitate targeted phishing attempts impersonating the optician.

What you can do
- Expect phishing attempts quoting your name and this company. A message that knows your details is not legitimate for that reason.
- Health data is “special category” data under the GDPR: a leak opens a right to compensation, and the organisation must notify the DPA within 72 hours.
- You can ask the organisation exactly what was exposed about you (right of access), and complain to the DPA if no answer comes within a month.
