Substantial Risk
IP 45.135.194.95, registered in the Netherlands and operated by Pfcloud UG through ASN 51396, is a high-risk address with a threat level of 8 out of 10, supported by an exceptionally high volume of 2,352 abuse reports from 20 distinct automated honeypot sensors. The dominant activity profile indicates active hacking intrusion attempts, with the IP recently flagged for both general hacking operations and exploitation as a compromised attack platform, suggesting dual risk vectors that demand immediate defensive attention.
Analysis of the detection data reveals a concentrated threat pattern within October 2025, with 18 of the 20 most recent reports categorizing the activity as hacking-related intrusion attempts and an additional 2 reports identifying this address as an exploited host being weaponized without the operator's knowledge. The 59% confidence score and 2,352 total reports indicate sustained malicious behavior over a compressed timeframe, despite the stated activity frequency metric appearing low. The Netherlands-based hosting infrastructure operated by Pfcloud UG suggests the originating system itself may be a rented cloud node, which explains the "exploited host" classification and the difficulty in establishing definitive attribution at this confidence level.
Hacking activity originating from this IP encompasses automated vulnerability exploitation, unauthorized access attempts, and the deployment of attack vectors against exposed services across the internet. The simultaneous classification as an exploited host indicates that the underlying infrastructure may have been compromised or is being rented for offensive operations, posing risks both as an active attack source and as an indicator of broader infrastructure compromise within this provider's network. Organizations with internet-facing services should treat any connection attempt from this address as potentially malicious, with particular concern for services running outdated or unpatched software that could be targeted through scripted exploitation toolkits.
Site operators should implement immediate blocking of IP 45.135.194.95 at the firewall or network edge to prevent reconnaissance and attack traffic. Services exposed to this address should be audited for compliance with security best practices, ensuring all software is patched and up to date. Implementing fail2ban or equivalent dynamic blocking defenses can automatically respond to suspicious patterns, while strong authentication requirements for administrative interfaces reduce the likelihood of successful intrusion. Organizations should also consider filing an abuse report with Pfcloud UG to facilitate potential takedown of the compromised infrastructure and notify relevant network operators about the malicious activity originating from this Netherlands-hosted address.
