Ransomware Disrupts Operations at Italian Water Management Company

May 22, 2023


Alto Calore Servizi SpA, an Italian company that provides drinking water to nearly half a million people said a recent hack rendered all of their IT systems unusable.

The company runs the collection, supply and distribution of drinking water for 125 municipalities Avellino and Benevento β€” two provinces in southern Italy. β€œIt will not be possible to carry out any operations or provide information that requires querying the database,” the company said.

The organization did not respond to requests for comment about whether customers are impacted by the incident, but it appears the distribution of water is not affected by the attack.

The Medusa ransomware group took credit for the attack and said it took customer data, contracts, minutes from board meetings, reports, pipe distribution information, expansion documents and more.
