What Happened? On January 15, 2026, while investigating an unsuccessful phishing attempt, HCCI discovered historical suspicious activity in connection with an employee’s email account. In response, HCCI promptly initiated an investigation with the assistance of third-party forensics specialists and moved swiftly to remediate the unauthorized activity.
The third-party investigation revealed evidence of a successful historical phishing attack that resulted in unauthorized access to the employee’s account from August 22, 2024 to November 6, 2024. As such, HCCI engaged a third-party data analytics firm to conduct a review of the email account to determine the types of information potentially accessible and to identify to whom the information relates. This review completed on June 11, 2026, at which time, HCCI determined that certain protected information may have been subject to unauthorized access by the unauthorized actor. Thereafter, HCCI moved swiftly to notify potentially affected individuals and regulators as required by law.
