Cautionary Risk
213.209.157.201 is a moderate-risk IP address linked to email spam activity, with 1497 total abuse reports logged against it and a threat level of 5/10, originating from a German hosting provider within the AS208485 autonomous system operated by Moon Dc.
The address was first and last reported in October 2025 according to the available data, with all 1497 reports attributed to automated honeypot sensors detecting SMTP spam and email abuse patterns. Despite the high report volume, the activity frequency score of 0/10 indicates the IP has not exhibited recent malicious behavior, suggesting the abuse may have ceased or the address has been taken offline since the initial detection period. The geographic location in Germany and association with a data centre operator points to a compromised or abused hosting environment rather than a residential botnet node.
Email spam represents one of the most prevalent threat vectors in network abuse, functioning as the delivery mechanism for phishing campaigns, credential-harvesting schemes, and malware distribution. An IP flagged for SMTP spam abuse typically indicates unauthorized relay activity or a compromised mail server being exploited to send bulk unsolicited messages while evading reputation-based filters. The scale of 1497 reports against this single address suggests sustained abuse rather than a transient incident, raising the risk that this infrastructure was deliberately used to circumvent email security controls at target organisations.
Site operators running publicly accessible mail services should block or closely scrutinize inbound connections from 213.209.157.201 and implement SPF, DKIM, and DMARC authentication protocols to prevent spoofing and validate incoming mail legitimacy. Deploying reputation-based filtering using blocklists populated from sources such as this IP's abuse reports will further reduce unwanted contact. Configuring fail2ban or equivalent dynamic blocking tools to automatically reject repeated SMTP connection attempts from abusive sources provides an additional layer of automated defense without manual intervention.
