About this breach
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.
