Incident analysis

Petrocare Construction was listed by Storm ransomware, a group with 118 victims recorded in this database. The listing appeared on the group's leak site on September 3, 2026.

Petrocare Construction is based in Canada and operates in the Energy & Utilities sector. Canada ranks #4 worldwide for ransomware disclosures, with 982 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.

Storm 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files are encrypted, so the victim faces two demands at once — pay to restore access, and pay to keep stolen data unpublished.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 .
