Royal Chemical Data Breach Exposes Sensitive Personal Information
Royal Chemical, a privately held chemical manufacturing and industrial services company, recently disclosed a data breach that compromised the sensitive personal information of consumers. The breach was reported to the Massachusetts Office of Consumer Affairs and Business Regulation on March 24, 2026, with four Massachusetts residents confirmed as affected.
The incident originated on May 14, 2025, when the Lynx ransomware group claimed responsibility via a post on the Tor network. The group asserted that Royal Chemical had been targeted in a ransomware attack and that stolen data including full names and Social Security numbers had been exfiltrated.
In response, Royal Chemical issued written notifications to impacted individuals. The company also advised affected parties of their right to one free credit report annually from each of the three major credit bureaus, accessible via AnnualCreditReport.com or by phone at 1-877-322-8228.
The breach highlights ongoing risks in industrial sectors, where ransomware groups continue to target organizations handling sensitive personal data.
