Moderate Risk
IP 158.94.209.59 is a medium-risk German address associated with 917 abuse reports, primarily involving email spam distribution, detected by automated honeypot sensors throughout October 2025.
Analysis of available telemetry indicates this address, operated by metaspinner net GmbH under autonomous system AS209800, carries a threat level of 5 out of 10 with a moderate confidence score of 61 percent. The substantial report volume of 917 incidents stands in apparent contrast to the zero-out-of-ten activity frequency score, suggesting the bulk of historic abuse reports accumulated prior to the current reporting window, with the most recent submissions numbering approximately 20 from automated honeypot sources during October 2025. All identified recent threat categories consistently point to email spam activity, indicating a focused pattern of mass unsolicited email distribution rather than diversified attack vectors. The German network registration and moderate confidence weighting provide reasonable geographic and organizational context for this infrastructure.
Email spam represents a persistent threat category involving the mass distribution of unwanted electronic messages, frequently employed as a delivery mechanism for phishing campaigns, malicious attachments, or advertising content. The volume of 917 historical reports suggests this address has participated in sustained spam operations at some scale. While the current activity frequency registers as minimal, the moderate confidence score means the characterisation of past behaviour carries reasonable evidentiary support. For exposed mail servers and open relay configurations, such addresses pose risks including resource consumption, reputation damage to legitimate mail streams, and potential gateway for targeted phishing attempts against users within the target environment.
Site operators maintaining publicly accessible mail services should implement layered email authentication protocols including Sender Policy Framework, DomainKeys Identified Mail, and Domain-based Message Authentication Reporting and Conformance to validate incoming messages and reject spoofed senders. Deploying reputable email filtering services with real-time blacklist integration provides proactive blocking of known spam sources. Monitoring inbound traffic patterns and implementing connection rate limiting can mitigate flood-style abuse. Where activity is not expected from German-based hosting infrastructure, adding this address or its associated AS209800 prefix to explicit blocklists represents a proportionate defensive measure.
