DyStar Group Hit by Settra Ransomware Attack, 1.3 TB of Internal Data Exfiltrated
DyStar Group, a global specialty chemical company, was reportedly targeted by the Settra ransomware group. The attackers claimed to have exfiltrated 1.3 terabytes of internal files. Multiple cybersecurity intelligence platforms listed DyStar as a victim, with reports indicating the incident occurred around June 2026. The exfiltrated data is alleged to include internal files, and some reports also indicate compromised employee and user credentials, as well as third-party employee credentials. DyStar's own sustainability reports, however, stated 'Zero cases reported on customer data loss or breaches of privacy' for the 2024-2025 period, which contradicts these external reports.
