The Lyon Firm is investigating a Fertility Centers of Illinois data breach incident on behalf of victims and plaintiffs in Illinois and nationwide. The firm is currently involved in several class action security breach and personal privacy cases, seeking compensation and legal justice.

The Fertility Centers of Illinois data breach is part of a larger ransomware attack that targeted US Fertility, the largest network of fertility centers in the country. US Fertility has said some of its IT systems were encrypted in a September 2020 data breach.

Fertility Centers of Illinois is one of 55 US Fertility locations across 10 states. IVF/fertility practices in the US Fertility network include Shady Grove Fertility, Reproductive Science Center San Francisco, IVF Florida, and Fertility Centers of Illinois.

The Fertility Centers of Illinois data breach and the larger US Fertility security incident were the result of a confirmed malware infection. US Fertility says Fertility Center data was encrypted by ransomware.

Protected health information was stolen in the US Fertility attack, potentially compromising patient data, including:

  • Names
  • Addresses
  • Dates of birth
  • MPI numbers
  • Social Security numbers

The types of information stolen from Fertility Centers of Illinois patients may vary by individual. Privacy attorneys are concerned sensitive biometric data may have also been impacted.

The Lyon Firm is investigating the US Fertility data breach and is actively involved in numerous data privacy cases and has experience filing data security claims on behalf of plaintiffs nationwide.
