When Alcon did not comply, the group published data they claimed to have sourced from the company. ## What was exposed The published data contained around 218,000 unique email addresses. According to HIBP, the remaining fields were largely corporate business-to-business contact information, including names, phone numbers, and physical addresses. ## Who is affected Approximately 218,395 individuals are listed in the exposed dataset. Given the B2B nature of the contact fields, those affected are likely business contacts, partners, or customers of Alcon rather than general consumers. ## What to do now If you have a business relationship with Alcon, be alert for phishing emails or unsolicited calls that use your contact details. Consider using a unique email alias for business communications going forward. Monitor your inbox for suspicious messages and report any unusual contact attempts to your IT or security team. ## Sources - [Alcon breach record](https://haveibeenpwned.com/PwnedWebsites#Alcon): HIBP; primary source; publisher: haveibeenpwned.com; confidence: 90/100; retrieved: 2026-09-29.
