Incident analysis

ARRCO LSM was listed by Ralord ransomware, a group with 19 victims recorded in this database. The listing appeared on the group's leak site on April 15, 2025.

ARRCO LSM is based in Norway and operates in the Consumer Services sector. Norway ranks #45 worldwide for ransomware disclosures, with 57 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.

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files are encrypted, so the victim faces two demands at once — pay to restore access, and pay to keep stolen data unpublished.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