The following attack categories were identified:
46.4.105.103 is registered in Falkenstein, Germany, operating on the network of Hetzner Online GmbH. This IP first appeared in our threat feeds after triggering multiple behavioral detection signatures. Over a period of 1 days, this IP generated 10 malicious requests, averaging approximately 10 requests per day. Operating from datacenter infrastructure, this IP is typical of addresses used in organized attack operations. Cloud and VPS providers are commonly exploited as launching platforms for automated scanning. The combination of 3 distinct attack vectors indicates a sophisticated, multi-pronged threat actor deploying automated tools that probe multiple attack surfaces simultaneously. Germany currently accounts for 63 blocked IPs in our database, making it a notable source of malicious traffic. A score of 110/100 places this address in the top tier of severity. Block and investigate any historical connections.
This IP belongs to a hosting or data center provider. Malicious traffic from hosting infrastructure often originates from compromised VPS instances, rented servers used for scanning campaigns, or abused free-tier cloud accounts. Hosting providers typically respond to abuse reports within 24-72 hours.
Examining HTTP headers beyond User-Agent reveals attack tools and automated scripts. Missing standard headers, unusual ordering, non-standard values, and inconsistencies with claimed client identity all serve as reliable detection signals.
Satellite internet introduces unique security challenges including high latency that affects real-time threat detection, shared bandwidth that enables traffic sniffing, and coverage areas that cross multiple jurisdictions complicating legal response.
