Aon Data Breach Investigation

Migliaccio & Rathod LLP is currently investigating the Chicago, Illinois-based Aon PLC (“Aon”), which recently notified 119,636 individuals that their protected health information was accessed by an unauthorized third-party between December 29, 2020, and February 26, 2022. The impacted information includes the following: Social Security numbers, driver’s license numbers, and benefit enrollment information.

Aon only recently began notifying victims of the data breach. Due to this lapse in time between the data breach and the notice to affected individuals, as well as the access the unauthorized cybercriminal(s) had to the impacted information for over a year, hackers may have already been able to acquire and sell the data and otherwise benefit from the fraudulent misuse of such information. Some individuals affected by the data breach may have already noticed (or may soon notice) one or more of the following types of fraudulent activity related to their personal and health information: unauthorized credit card inquiries and/or charges, requests for loans or benefits in a patient’s name without their consent, fake medical procedures ordered, and/or disrupted use of the institution’s website.
