As many of you are aware, Illinois Heartland Library System (IHLS) is the billing agent for the Illinois State Library for Online Computer Library Center (OCLC) services. This email is to inform you that at approximately 4 a.m. Wednesday, October 23, 2019, the company that provides IHLS with support for the financial software used for OCLC billing was infected with a virus. This virus spread to servers that support our billing for OCLC at IHLS. Our IT department was able to remove the virus and the root cause of the attack. The system is back to normal with all of our data intact. We are very confident that no financial data was stolen or accessed. However, the only data that could have been accessed was our customer information files. This may include your name, email, and business mailing address that was listed in our customer files. We do not store any bank or credit card information in our software or electronic files.
If you have any concerns, please feel free to contact me.
