Extreme Threat
IP 161.97.133.133 is a critical-risk address originating from Germany that has generated 238 abuse reports, with all recent activity classified as general hacking attempts including intrusion and exploitation attempts against exposed services. The volume of reports combined with the maximum threat score of 10/10 indicates this IP poses a severe and persistent danger to any internet-facing infrastructure it targets.
Analysis of the available intelligence reveals 238 total reports attributed to this address, with 20 recent reports specifically categorised as hacking activity. All detections originated from automated honeypot sensors, which detected the malicious traffic during November 2025. The IP is registered to Contabo GmbH, operating within AS51167, a German hosting provider commonly associated with automated threat actors due to the volume of services it offers. Despite the extremely high report volume, the activity frequency metric of 0/10 suggests the IP may currently be in a dormant phase, though historical data confirms sustained malicious behaviour over the reported timeframe.
The dominant threat category of hacking encompasses a broad spectrum of intrusion attempts, vulnerability exploitation and unauthorized access attempts against exposed services. For network operators, this classification signals that the address has been actively probing for weaknesses rather than conducting a single attack type. The real-world risk includes potential credential compromise, service disruption or initial access broker activity that could lead to more sophisticated follow-on attacks against targeted systems. The 76% confidence score indicates a well-established threat profile with reliable attribution to malicious intent.
Site operators should immediately block or rate-limit connections from 161.97.133.133 at the firewall level and monitor logs for any successful connections. Implementing strict authentication requirements including multi-factor authentication on all exposed services significantly reduces the impact of credential-based intrusion attempts. Deploying automated blocking tools such as fail2ban or equivalent solutions can dynamically respond to repeated connection attempts from this address. Maintaining current patches and intrusion detection monitoring across all internet-facing assets provides essential defence against the exploitation techniques associated with this threat actor.
