# Laboratoire LCS

Data breach — Moderate

On September 29, 2026, a user going by the pseudonym "Syrv4x" published a database attributed to Laboratoire LCS, a French custom contact lens manufacturer based in Normandy, for free on a cybercrime forum. The claimed file, roughly 7 MB and 42,495 rows, links names, surnames and dates of birth to contact lens order details (type, date), spanning 2014 to mid-September 2026. Laboratoire LCS has not publicly confirmed the incident, and how the data was obtained remains unknown.

Combining identity data with contact lens order history could make phishing messages impersonating a known professional or brand more convincing.
