US Fertility, the largest network of fertility centers in the U.S., says some of its systems were encrypted in a ransomware attack two months ago. USF took down the impacted servers and workstations after discovering the attack. The company says Social Security numbers and MPI numbers were not affected by the malware attack. It is the largest fertility network in the country, with 55 locations across 10 states and 130,000 babies born with the help of partner IVF practices in the USF network.
