NordVPN has denied a breach following claims from a hacker who posted data allegedly stolen from its systems on the BreachForums cybercrime forum. The hacker stated they accessed NordVPN's development server by exploiting a misconfigured server, claiming to have obtained source code and internal information. In response, NordVPN initiated an investigation and reported that its forensic analysis found no signs of compromise within its servers or infrastructure. The company clarified that the leaked data does not originate from its Salesforce environment or other internal systems. Instead, it appears to come from a third-party automated testing platform that NordVPN evaluated six months prior. During that trial, a temporary environment was created, but it was never connected to production systems, and no real customer data or credentials were involved. NordVPN emphasized that the leaked elements were merely artifacts from this isolated testing environment, containing only dummy data used for functionality checks.
