On October 22, 2021, IGG discovered unusual activity within its computer network. IGG immediately launched an investigation, with the assistance of third-party cybersecurity specialists, to determine the nature and scope of the event. On November 18, 2021, the investigation determined that an unauthorized actor gained access to certain IGG systems and that information contained in those systems may have been viewed or taken by the unauthorized actor.
IGG reviewed the information contained within the systems to identify if any individuals’ personal information or protected health information was potentially impacted. On March 22, 2022, IGG determined personal information of individuals including the following types of information that IGG maintains in its systems and that were, or may have been, impacted by this incident include: name, address, date of birth, Social Security number, driver’s license, Passport, financial account information, payment card information, employer-assigned identification number, medical information, and biometric data. To date, IGG has not received any reports of fraudulent misuse of any information potentially impacted.
IGG provided a lot more detail on their improvements/responses to harden security than we usually see in notifications. Specifically, they write:
In response to this incident, IGG augmented its policies and procedures addressing network security. IGG accelerated the implementation of an enhanced managed Security Operations Center including the deployment of an endpoint detection and response platform in response to this event with policies enabled specially for ransomware.

IGG is also notifying potentially affected individuals so that they may take further steps to protect their information, should they feel it is appropriate to do so.
