The statement follows a new wave of incidents on 1–2 November, after initial reports dating from 11 October. National authorities are investigating, while European networks exchange information to coordinate the response.

In France's health sector, EFS says an incident at a refrigeration supplier affected three sites, with no blood products lost or health consequences identified. This statement is not independent verification of all effects. The consulted sources do not establish that all European incidents form a single operation.

According to Euronews, Italy’s cybersecurity agency issued technical recommendations to retailers. The incidents form part of a European series, but no perpetrator or motive has been established. Available information does not establish that every malfunction belongs to a single operation.
