Critical Threat
IP 172.245.112.205 is a critical-risk address assigned to AS-COLOCROSSING (AS36352) in the United States, responsible for 401 confirmed hacking intrusion attempts detected by automated honeypot sensors between August 2025 and May 2026.
Security monitoring systems logged 401 abuse reports attributing this IP to sustained unauthorized access attempts and vulnerability exploitation activity. The detection confidence of 93% reflects consistent attack signatures observed across multiple honeypot sensors over an approximately nine-month period. Activity frequency scored 8/10 indicates near-continuous engagement with target systems, suggesting an automated or semi-automated attack infrastructure rather than isolated manual probing. The network is operated by AS-COLOCROSSING, a hosting provider known for accommodating diverse customer traffic, which aligns with the high-volume threat profile observed.
The dominant hacking classification encompasses multiple intrusion techniques including exploitation of software vulnerabilities, brute-force authentication attacks, and probing for misconfigured services. For organizations running exposed SSH, RDP, web applications, or other network-accessible services, this IP represents a direct pathway for unauthorized system access, credential theft, and potential network pivoting by threat actors. The sustained activity pattern indicates the address is likely part of coordinated scanning campaigns or botnet-driven operations rather than opportunistic single-attempt activity.
Site operators should block 172.245.112.205 at the firewall level and implement rate-limiting on authentication endpoints to mitigate credential-stuffing attempts. Deploying fail2ban or equivalent log-analysis tools can automatically ban repeat offenders based on failed login patterns. Regular patching of exposed services, enforcement of strong authentication credentials, and monitoring of authentication logs for this IP address will reduce exposure to the exploitation techniques this actor employs.
