Overview
- University officials said a research‑lab PC showed a 'Lock Bit Black' ransom message when it was started on May 25 and was immediately disconnected to stop further spread.
- Kyushu University publicly disclosed the incident on June 10 and said files on the device may have included the names and surgical video recordings of 43 hospital patients.
- The hospital has contacted and apologized to the potentially affected patients and says it is working with prefectural police to determine the cause and scope of the intrusion.
- Hospital leaders report that core clinical systems such as electronic medical records were not affected and that there is currently no confirmation that the data were published or abused.
- Security experts say this case highlights how research or ancillary devices on hospital campuses can create attack paths separate from clinical networks and investigators will watch whether the probe leads to wider security changes or disclosures.
