GreenSlate LLC

In December 2021, GreenSlate LLC experienced a data breach caused by insider wrongdoing, as reported by the Maine Office of the Attorney General in March 2022. The incident, which occurred between December 10 and December 15, resulted in the compromise of sensitive personal information for **50,217 individuals**. The exposed data included **names, Social Security Numbers (SSNs), and financial account details**, posing severe risks of identity theft, financial fraud, and long-term reputational harm. The breach stemmed from internal misconduct, highlighting vulnerabilities in the company’s insider threat detection and access controls. Given the nature of the stolen data—particularly SSNs and financial records—the affected individuals face heightened exposure to fraudulent activities, including unauthorized account openings, loan applications, and tax fraud. The scale of the breach and the sensitivity of the compromised information underscore the critical need for robust internal safeguards and proactive monitoring to prevent similar incidents in the future.
