Tekni-Plex, Inc., a global advanced manufacturing and materials science company, suffered a data breach discovered on November 18, 2024. An unauthorized third party accessed its network between October 24, 2024, and December 7, 2024, exfiltrating sensitive personal data. The compromised information includes names, Social Security numbers, driver’s license numbers, and financial account details highly valuable for identity theft and fraud. The breach has prompted a class-action investigation by Edelson Lechtzin LLP, focusing on legal remedies for affected individuals. The incident exposes victims to long-term risks, including financial fraud, credit damage, and potential misuse of personally identifiable information (PII). Tekni-Plex has not disclosed the scale of the breach, but the nature of the stolen data suggests severe reputational harm and regulatory scrutiny. Affected individuals are advised to monitor financial accounts and credit reports for suspicious activity.
