Livingston Street Capital, LLC

Livingston Street Capital, LLC suffered a phishing data breach between May 2, 2023, and May 3, 2023, compromising the personal information of 1,347 individuals, including three Maine residents. The breach involved unauthorized access to sensitive data, likely through deceptive emails targeting employees or systems. While the exact type of exposed data was not specified, the company’s response—offering identity theft protection services—suggests the leak may have included personally identifiable information (PII) such as names, addresses, Social Security numbers, or financial details. The delayed notification to affected individuals (sent on October 26, 2023) indicates a prolonged investigation or internal handling before public disclosure. The breach’s scale, though not massive, poses risks of identity theft, financial fraud, or reputational harm to those impacted. The incident underscores vulnerabilities in the company’s cybersecurity defenses, particularly against social engineering tactics like phishing, which remain a prevalent threat vector for data exfiltration.
