Incident analysis

Eversource Energy was listed by Redact ransomware, a group with 6 victims recorded in this database. The listing appeared on the group's leak site on October 12, 2026.

Eversource Energy is based in United States and operates in the Energy & Utilities sector. United States ranks #1 worldwide for ransomware disclosures, with 9,988 victims in this database.

Sector context. Organisations in this sector hold valuable data and operational systems that ransomware groups seek to exploit for financial gain through encryption and data exfiltration.

Redact typically follows a double extortion model: data is exfiltrated from the victim's systems before files are encrypted, so the victim faces two demands at once — pay to restore access, and pay to keep stolen data unpublished. The leak site, where this listing appeared, is the lever for the second demand.

Source. Public leak-site disclosures aggregated via the ransomware.live API. The disclosure date is when the listing was published, which can differ from the date of compromise. This site does not publish or link to stolen data. Last updated .
