Incident Analysis

Bay State Land Services was targeted by Sinobi ransomware, one of the most active ransomware groups in our database with 274 confirmed victims globally. The attack was disclosed on May 5, 2026, when Bay State Land Services appeared on the group's dark web leak site.

Bay State Land Services is based in United States , operating in the Construction sector. United States ranks #1 globally for ransomware attacks, with 9,006 victims in our database.

Sector context: Construction firms often hold sensitive project data, client financials, and intellectual property. The industry's typically lean IT security teams can make them more vulnerable.

Sinobi typically employs a double extortion model: first exfiltrating sensitive data from the victim's systems, then deploying ransomware to encrypt files. Victims face two simultaneous threats โ€” paying to restore access and paying to prevent publication of stolen data. The group's leak site publishes victim names and exfiltrated data as leverage.

Data source: This incident record is sourced from public ransomware group leak site disclosures aggregated via the ransomware.live API. Disclosure date reflects when the victim was published on the leak site, which may differ from the initial date of compromise. This platform does not publish or link to stolen data.
