Elevated Risk
IP 185.132.46.108, hosted on IONOS SE's network in Germany (ASN AS8560), presents a high-risk threat profile with a threat level of 8/10 and a confidence score of 92%, based on 410 abuse reports submitted through automated honeypot sensors. The dominant malicious activity is VoIP fraud, accounting for the overwhelming majority of recent threat categorisations. Activity frequency is rated 8/10, indicating persistent and repeated exploitation attempts rather than isolated scanning behaviour.
Analysis of the report data reveals that this address has been flagged 410 times, with 20 of the most recent reports specifically categorising the activity as VoIP fraud and one additional report noting general hacking activity. The detection footprint spans the first reported date in May 2026 through the last reported date in May 2026, suggesting concentrated activity within a defined window. All 20 most recent report sources are attributed to automated honeypot sensors, which detected patterns consistent with VoIP infrastructure exploitation. Network-level context places this IP within IONOS SE's substantial autonomous system, a large commercial hosting provider whose resources are frequently leveraged for both legitimate and malicious purposes due to the scale and accessibility of their infrastructure.
The VoIP fraud threat category represents a financially motivated attack vector that exploits telephone systems to route or initiate unauthorised calls, often directed toward premium-rate or international numbers to generate illicit revenue. The detected Suricata stream spurious retransmission alert further indicates reconnaissance or protocol-level manipulation attempts against exposed VoIP services. For organisations operating SIP-based systems, session border controllers, or open telephony infrastructure, such an IP poses a direct risk of service abuse, unauthorised toll fraud, and resource consumption that can result in significant financial losses and service degradation.
Site operators should implement immediate defensive measures including blocking or rate-limiting traffic from this IP at the firewall or network edge, configuring fail2ban or similar intrusion-prevention tools to auto-ban repeat offenders, and hardening VoIP authentication through strong credentials, SIP ALG review, and call pattern monitoring to detect anomalies. Regularly reviewing SIP access logs, restricting international and premium-rate dialing capabilities, and ensuring all telephony software remains patched against known vulnerabilities will further reduce exposure to the exploitation patterns associated with this address.
