SEL5802958091325
Sellmark Corp. suffered a significant data breach where an unauthorized actor infiltrated its internal network between March 10, 2025, and April 14, 2025, exfiltrating files containing personally identifiable information (PII). The compromised data included names, Social Security numbers, driver’s license/government ID numbers, and financial account details. While the exact number of affected individuals remains undisclosed, initial reports suggest thousands were impacted, with confirmed cases including 1,205 in Texas, four in New Hampshire, and one in Maine.The breach was formally reported to state Attorney Generals' offices on September 11, 2025, and affected individuals were notified via mail. Sellmark responded by securing its systems, involving law enforcement, and offering 12 months of free Experian IdentityWorks identity monitoring to victims. A dedicated helpline was also established to address concerns. The exposure of highly sensitive financial and identity-related data poses severe risks, including identity theft, fraud, and phishing attacks targeting the victims.
