Description

On August 25, 2017, security specialists monitoring Tettegouche State Park’s computer systems detected a spike in unusual activity around 4:00 PM, leading to the discovery of a malware infection. The Minnesota Department of Natural Resources (DNR) confirmed the incident on September 8, initiating immediate containment measures that included isolating affected systems, safeguarding sensitive data, and replacing compromised hardware. Forensic analysts launched a full investigation to determine the attack’s origin and scope, though authorities did not disclose specifics about the malware variant or the exact timing of the initial breach. The DNR identified a vulnerable timeframe spanning August 22 to August 25, during which approximately 400 credit card transactions occurred at the park’s facilities in Silver Bay. While no evidence confirmed credit card data exfiltration, the DNR advised impacted visitors to scrutinize their financial statements for unauthorized charges and remain vigilant against phishing emails impersonating the agency. The department clarified it could not directly notify affected individuals due to restrictions preventing access to customers’ personal information linked to payment records.

The malware’s impact remained confined to Tettegouche State Park’s local computers, with no compromise of broader DNR infrastructure, including the statewide park reservation system or public-facing websites. Officials reiterated that reservation data remained secure and unrelated to the incident. Minnesota IT Services collaborated with the DNR to investigate potential data exposure, though forensic reviews had not identified confirmed theft of sensitive information at the time of reporting. The DNR emphasized its proactive measures to replace infected equipment and maintain system integrity while continuing to analyze the attack’s methodology. No additional details regarding attacker tactics, malware functionality, or remediation timelines were released publicly during the initial response phase.
