Moderate Risk
IP 213.165.52.9 is a moderate-risk address linked to email spam abuse, detected by automated honeypot sensors with a threat level of 5 out of 10 and a confidence score of 58 percent. This German IP, registered to AS199785 under Cloud Hosting Solutions, Limited, has accumulated 164 total reports with 20 recent email spam detections, all activity confined to September 2025.
The detection data shows concentrated abuse originating from a single reporting period, with automated honeypot infrastructure flagging SMTP spam behaviour. While the total report volume of 164 indicates sustained attention from detection systems, the activity frequency score of 0 out of 10 suggests limited ongoing engagement. The moderate confidence score of 58 percent reflects partial certainty in attributing the observed patterns to deliberate malicious activity versus incidental misconfiguration or shared infrastructure behaviour.
Email spam constitutes a significant threat vector where compromised or malicious systems distribute bulk unsolicited messages to harvest credentials, deliver payloads, or conduct phishing campaigns. The detected SMTP abuse indicates this IP has been used to relay or originate spam, directly threatening email infrastructure and creating reputational risk for the associated network operator. Organizations with exposed mail servers face the risk of receiving spam originating from or relayed through this address, potentially exposing end users to credential theft or malware.
Site operators should implement email authentication standards including SPF, DKIM, and DMARC to validate incoming messages and reject unauthenticated relay attempts. Deploying reputable email filtering services and maintaining updated blocklists for known spam sources will reduce exposure. Monitoring for new abuse reports and configuring automated response tools such as fail2ban to detect and block repeated SMTP abuse attempts provides additional protection against threats originating from this address.
