  • A Settlement has been reached with Illinois Gastroenterology Group P.L.L.C. (the “Defendant” or “IGG”) in lawsuits related to a cybersecurity disruption involving IGG’s computer network on October 22, 2021 (the “Data Breach”).
  • On November 18, 2021, an investigation conducted by IGG determined that an unauthorized third-party cybercriminal gained access to IGG’s systems, and that information contained in those systems for approximately 227,943 individuals may have been compromised by the third-party threat actor in the Data Breach. Settlement Class Members’ PII, PHI, and PBI, including names, addresses, dates of birth, Social Security numbers, driver’s licenses, passports, financial account information, payment card information, employer-assigned identification numbers, medical information, and biometric information, may have been compromised in the Data Breach.

Lake Cnty.) lawsuit was filed against IGG asserting claims arising from the Data Breach. In addition to the McNicholas lawsuit, several other lawsuits were filed against IGG asserting claims arising from the Data Breach.
