Summary (Bottom Line Up Front)
Hong Kong-based IP address 43.132.207.18 conducted 147 reconnaissance attempts against FortiGate infrastructure between March 9-20, 2026, employing automated scanning techniques to probe for vulnerabilities and access points. This activity represents a LOW severity threat with moderate confidence, consistent with preliminary reconnaissance phases of a potential exploitation campaign. Network defenders should implement enhanced monitoring for FortiGate devices and prepare for possible escalation to active exploitation attempts.

This activity represents a LOW severity threat with moderate confidence, consistent with preliminary reconnaissance phases of a potential exploitation campaign. Network defenders should implement enhanced monitoring for FortiGate devices and prepare for possible escalation to active exploitation attempts.
Technical details
The threat actor utilized TCP, TLS 1.0, and HTTPS protocols across two unique destination ports during an 11-day campaign spanning March 9 20:00 to March 20 15:00, 2026. Primary attack vectors included FORTI_PROBE activities (20 instances) targeting unknown paths and FORTI_RECON operations (2 instances) focused on login page enumeration, aligning with MITRE ATT&CK technique T1595.002 (Active Scanning: Vulnerability Scanning). The campaign originated from ASN-unattributed infrastructure in Hong Kong with a moderate AbuseIPDB reputation score of 27/100, suggesting coordinated reconnaissance rather than opportunistic scanning. No CVE exploitation attempts were observed, with zero-day probability assessed at 5%.

Recommendations
- Implement enhanced logging and monitoring for all FortiGate devices, particularly focusing on unusual authentication attempts and path enumeration activities
- Deploy network segmentation controls to limit lateral movement potential from internet-facing FortiGate appliances
- Review and harden FortiGate configurations, ensuring default credentials are changed and unnecessary services are disabled
- Establish threat hunting procedures to identify similar reconnaissance patterns against other network infrastructure devices
- Consider blocking traffic from IP 43.132.207.18 and monitor for additional Hong Kong-based scanning activity targeting FortiGate systems
