Novocure's SEC filing names no vector and no actor for the unauthorized access it discovered in mid-August 2026, only the aftermath. More than 1,400 U.S. patients had ID numbers exposed without names, while fewer than 50 in the western U.S. lost both identity and provider contact details, a split that reads like several systems failing on different terms, not one breach. Employee names, job titles, and phone numbers leaked from the same event, which the filing still frames as a story about untouched treatment devices. No devices were breached, they say; the record of who these patients are was.
