Enessance: ransomware attack

On 21 October 2025, ransomware encrypted data on some servers and devices of the Enessance group, an LP gas retailer, and its systems went down. On 30 November it found data apparently stolen from it published on the attackers' leak site. The fourth report on 11 May 2026 said names, addresses, phone numbers, emails and more of about 365,000 customers, plus about 2,000 employee records, leaked or may have leaked. The entry point was not identified, but was most likely its internet connection. Toell, which used the group for gas delivery, disclosed about 310 of its own customers.
