Detailed summary

Daily Dark Web reported on June 4, 2025, that the Interlock ransomware group allegedly published 2.6 terabytes of data it claimed belonged to Kettering Health. The report connected the alleged leak to a cyberattack that had disrupted the Ohio healthcare network around May 20–21, 2025; the breach and the group’s claims were not officially confirmed in the material reviewed.

The report did not identify confirmed data types or an affected-individual count, and said Kettering Health had not detailed the nature or extent of the information. The available material does not establish whether the published data contained Social Security numbers, medical records, or financial information. Further details may emerge, and any consumer notices may be issued later.
