What happened
The San Francisco 49ers were added to the BlackByte ransomware group's leak site on February 12, 2022. The group claims to have stolen internal files in a ransomware attack. No further details on the timing of the intrusion, the method used, or the volume of data have been disclosed.
Who is blackbyte?
BlackByte is a ransomware operation that has been publicly active since at least 2021. The group follows a double-extortion model in which it both encrypts systems and threatens to publish stolen data if a ransom is not paid. It has listed victims across multiple industries on its leak site, a tactic used to increase pressure on targeted organizations.
About San Francisco 49ers
The San Francisco 49ers are a professional American football team in the National Football League. Organizations of this type maintain records related to employees, vendors, ticket holders, and business operations. A breach involving internal files can expose information that is not normally public and may include details about contracts, personnel, or day-to-day activities.
What was likely exposed
The only data category named in the listing is internal files exfiltrated during the ransomware attack. The exact types of records, file counts, or whether personal information of fans or staff was included have not been disclosed. Organizations in professional sports typically hold employee records, financial documents, and customer contact information, but it is not confirmed whether any of these categories were present in the claimed theft.
Why it matters
Internal files can contain operational details that affect business relationships and employee privacy. If personal information was among the files, affected individuals could face risks such as targeted phishing or identity misuse. For the organization, the incident adds to the list of known ransomware listings in the sports sector, where data handling practices are subject to standard regulatory expectations around security and notification.
If your data was in this claimed breach

Breach listings — particularly those originating from ransomware or leak sites — are third-party claims that may be unverified, incomplete, or inaccurate. A listing does not by itself confirm that a breach occurred or that any specific data was exposed. Severity is an automated assessment, not a definitive rating. Verification status is shown where available.
Attributions to threat groups and methods reflect public reporting and, in some cases, unverified claims made by the groups themselves; they may be incomplete or later revised.
