Comey said, considering that a foreign intelligence service could use the information to identify U.S. intelligence operatives, as example. At least 4.2 million people were affected by the breach of a separate database containing personnel records including Social Security numbers, job assignments and performance evaluations. OPM said these records include “findings from interviews conducted by background investigators and approximately 1.1 million include fingerprints.” Identification details such as Social Security Numbers, residency and educational history, employment history, information about immediate family and other personal and business acquaintances, health, criminal and financial history, and other details were stolen.The government declined to name the hackers, but said the same party was responsible for both hacks.
