Significant Threat
IP 185.218.138.11 is a moderate-to-high-risk address linked to sustained port scanning activity targeting network infrastructure, with 1,822 abuse reports filed through automated honeypot sensors and a threat level rated 7 out of 10.
The data reveals a concentrated campaign of reconnaissance: all 1,822 reports attribute the activity to port scanning, with the specific focus identified as Cisco ASA port scanning and probing. Detection occurred across 20 automated honeypot sensors over a four-month window between March 2026 and June 2026. The IP is registered in the United States under network operator Vlad Cojuhari, operating within AS205997. The activity frequency score of 8 out of 10 and the 91% confidence level indicate persistent, deliberate scanning behavior rather than incidental misconfiguration or transient automated traffic. The concentration of all reports into a single threat category underscores a focused operational pattern.
Port scanning constitutes the initial phase of most targeted attacks: identifying open services on Cisco ASA firewalls narrows an adversary's options for exploitation and enables precise weapon selection. While the scan itself does not directly compromise a system, it provides critical intelligence about an organization's exposed attack surface. A successful reconnaissance profile of firewall ports can inform subsequent intrusion attempts, making the detected scanning activity a meaningful early warning indicator for defenders.
Organizations with Cisco ASA deployments exposed to this IP should immediately review firewall rule sets and ensure only essential services are reachable from untrusted networks. Implementing strict inbound filtering, minimizing exposed services, and applying network segmentation reduce the value of any future scan data. Continuous monitoring for scanning patterns and automated blocking tools such as fail2ban can proactively neutralize repeated probes. Threat intelligence feeds correlating this IP reputation data further strengthen perimeter defense posture.
