Incident analysis

The Matlusky Firm LLC was listed by Blackshrantac ransomware, a group with 43 victims recorded in this database. The listing appeared on the group's leak site on October 31, 2025.

The Matlusky Firm LLC is based in United States and operates in the Business Services sector. United States ranks #1 worldwide for ransomware disclosures, with 10,151 victims in this database.

Sector context. Business services firms often have access to multiple client environments, making them high-value pivot points for ransomware operators seeking to maximise impact across multiple victim organisations.

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files are encrypted, so the victim faces two demands at once — pay to restore access, and pay to keep stolen data unpublished.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