Maximum Danger
IP 45.187.40.40 is a critical-risk address originating from Brazil with a threat level of 10 out of 10, linked to 16203 reported hacking intrusion attempts detected by automated honeypot sensors. This extremely high report volume within a concentrated timeframe establishes the IP as an aggressive threat actor in the START TELECOM network (AS269484).
The aggregate abuse data reveals significant malicious activity despite a moderate confidence score of 59 percent, with all 16203 reports originating from 20 distinct automated honeypot sensors. The IP was first and most recently reported in September 2025, indicating this is fresh threat intelligence. The geographic origin in Brazil places the source within the South American threat landscape, while the AS269484 allocation to START TELECOM suggests the activity originates from a telecom infrastructure provider, which is consistent with scanning or brute-force campaigns that abuse provisioned network resources. The activity frequency metric of zero out of 10 likely reflects that the reported events occurred in a concentrated burst rather than sustained continuous probing.
The dominant threat category of hacking encompasses general intrusion attempts, vulnerability exploitation and unauthorized access vectors targeting exposed services. For organizations running publicly accessible SSH, Telnet, FTP or web application services, such an address represents a concrete risk of credential compromise, service disruption or initial access broker activity that could precede more sophisticated attacks. The volume of reports suggests automated tooling rather than manual probing, indicating the IP is part of coordinated scanning infrastructure designed to systematically identify and exploit weak points across global target ranges.
Site operators should immediately block or rate-limit this IP at the firewall or load balancer level and audit access logs for any matching connection attempts during the reported September 2025 window. Implementing fail2ban or similar dynamic blocking tools across exposed authentication endpoints significantly reduces exposure to the automated scanning patterns this address represents. Organizations should enforce strong credential policies, disable unused services, apply security patches promptly and maintain intrusion detection monitoring to identify any successful compromise attempts originating from such sources.
