In August 2026, the Alcon eye care company was named in a ShinyHunters "pay or leak" extortion campaign. The group subsequently published data allegedly sourced from Alcon containing 218k unique email addresses along with other largely corporate B2B contact fields, including name, phone number and physical address.

What is not listed

Passwords
Bank details
Card numbers

So there is no password to change here — the usual first move does not apply.

The record shows what was found in the data. Not listed is not the same as proven untouched.

Source

A specialist service holds the stolen data, checks it is genuine, and lets anyone search their own address in it. The strongest evidence short of an official source.
