1. Email Authentication Anomalies: The incoming email appeared to originate from a legitimate address (craig@navpoint.com). A deep network sweep of the sender domain revealed it was running over unsecured HTTP without a valid SSL certificate and utilizing legacy webmail portals. This indicated a highly probable internal mail server or server-side routing compromise of the impersonated business.
2. Decoy Domain Infrastructure: The attacker provided a parallel web interface hosted on a secondary domain: navcloud9.com (IP: 72.237.30.50). A WHOIS database lookup revealed this was an aged domain originally created in 2016 but updated dynamically on January 7, 2026. Threat actors routinely leverage older, dormant domains to easily bypass standard email spam filters and signature-based firewall detection.
3. Malicious Staging Nodes: The attacker provided secure shell (SSH) credentials and instructed us to tunnel directly into a remote staging node located at 72.237.30.100 (resolving to ://navpoint.com). Network trace-routing confirmed this node lived on the exact same routing infrastructure as the main compromised business server (207.106.42.23), establishing that the threat actor had achieved deep operational foothold within the victimized ISP’s network.

• Zero Execution: No files were compiled, downloaded, or executed locally. No SSH handshakes were established with the malicious staging node (72.237.30.100).
• Local Endpoint Auditing: A full, deep-system cryptographic scan was executed via specialized anti-malware tools to guarantee our internal developer networks remained entirely pristine.
• Federal Reporting: All forensic data, server subnets, timeline summaries, and malicious domains were compiled and submitted to the FBI’s Internet Crime Complaint Center (IC3) under official Submission ID: 12b523a53b214487af03077d3c3b8fe6.
• Downstream Target Alerting: TekCo LLC bypassed the attacker entirely and issued an emergency security escalation directly from our corporate domain (salman@tekco.net) to the internal Information Security team at the American College of Surgeons. This provided their Security Operations Center (SOC) with the exact telemetry needed to revoke compromised administrative permissions and audit their active server logs.

1. Never Bypass Procurement for Speed: If a vendor or client refuses to execute a formal legal contract, state exactly what their rates are, or follow standard identity verification, stop the project immediately.
2. Implement Multi-Layered Domain Verification: Ensure your internal IT team or MSP actively checks incoming mail server records (SPF, DKIM, DMARC) and monitors for lookalike domains or unsecured HTTP servers.
3. Partner with a Proactive MSP: Standard IT shops simply fix broken printers. A true Managed Service Provider actively hunts threats, reviews network routing telemetry, and stands between your company data and global threat actors.
