NFL's San Francisco 49ers are mailing notification letters confirming a data breach affecting more than 20,000 individuals following a ransomware attack that hit its network earlier this year.
The San Francisco Bay Area professional American football team confirmed that personal information belonging to 20,930 impacted individuals was accessed and/or stolen in the attack between February 6 and February 11, 2022.
"The 49ers conducted a thorough review of these files to identify the individuals whose information was contained in the files, and additional research to locate and verify the addresses for these individuals," the team revealed in notification letters sent to affected individuals starting Thursday.
The BlackByte gang claimed responsibility for the attack on February 12, right as the NFL was getting ready for Super Bowl 2022, by starting to leak files claimed were stolen from the 49ers' network.
The ransomware group also leaked an archive containing 292 MB worth of files the gang said were invoices stolen from 49ers' compromised servers.
"We notified law enforcement and are fully supporting their investigation," the 49ers added in the data breach notification letters.
