What Happened?

Sansone Group, LLC — a nationwide commercial real-estate firm headquartered in St. Louis — discovered on June 24, 2025 that hackers had infiltrated its network during a two-day window from March 22 to March 24, 2025. The cyber-criminal syndicate HUNTERS INTERNATIONAL claimed responsibility, boasting on dark-web forums that it had exfiltrated roughly 2.4 terabytes of company data. The group threatened to publish the stolen files unless paid a ransom.
