About This Breach
Texas Attorney General record BR-0005172 publishes an incident period of 12 May through 3 June 2026 and a discovery date of 18 June. It reports 11,482 affected people nationwide, including 679 Texas residents; the state figure is included in the national total.
Frontier's official sample letter in the Massachusetts archive says the company secured the affected account. The public sources do not disclose the account type, initial access method, whether files were downloaded, malware, a ransom demand, or an actor. Those details should not be filled in without evidence.
What information may have been involved?
According to the official letter, possible fields varied by person and included first and last names, addresses, phone numbers, Social Security numbers, driver's license numbers, places and dates of birth, and designated contact information. Passport or visa numbers and Frontier employee identification numbers may also have been involved. Bank accounts, payment cards, passwords, medical information, health insurance information, and travel itineraries are not listed for this event in the official sources.
Organization response and safe next steps
Frontier said it secured the affected account, strengthened access controls and system monitoring, and implemented additional detection measures. It offered potentially affected team members 24 months of credit monitoring and identity protection; current eligibility and terms should be verified from the recipient's letter. People whose notice lists a Social Security, driver's license, passport, or visa number can review credit reports and relevant identity accounts for unfamiliar applications or changes. Identification, payments, passwords, and verification codes should not be shared through unexpected messages claiming to represent Frontier or a protection provider.
