Maximum Danger
IP 87.121.84.40 is a critical-risk address linked to sustained hacking activity, with 188 reports logged by automated honeypot sensors between January and May 2026. Operating from the United States under the AS215925 autonomous system administered by Vpsvault.host Ltd, this IP exhibits an activity frequency rating of 8 out of 10, indicating persistent and repeated intrusion attempts rather than isolated probes. With a threat level score of 10 out of 10 and a confidence rating of 94%, the assessment carries strong evidentiary support across 20 distinct detection events.
The detection data reveals a concentrated pattern of unauthorized access attempts detected exclusively through automated honeypot infrastructure, with each of the 20 most recent reports categorizing the activity as hacking. The five-month reporting window demonstrates that this is not transient or opportunistic scanning but rather sustained engagement against exposed services. The high confidence score reflects consistent detection across multiple sensor sources, reinforcing the reliability of the threat classification. Network attribution points to a commercial VPS provider, suggesting the activity originates from a hosted environment rather than a residential or mobile connection.
The dominant hacking classification encompasses general intrusion activity, including vulnerability exploitation attempts and unauthorized access probes against exposed network services. For any organization running internet-facing systems, this profile represents a concrete risk of credential compromise, service disruption, or initial access broker activity that could precede more sophisticated attacks. The persistent nature of the activity suggests automated tooling scanning for known vulnerabilities at scale, targeting systems that may lack adequate patching or hardening.
Defensive measures should include implementing automated threat-blocking tools such as fail2ban to dynamically ban IPs exhibiting brute-force behavior, enforcing strong authentication requirements on all exposed services, and maintaining rigorous patch management schedules. Network operators should consider blocking or rate-limiting traffic from this address at the perimeter, and security teams should ensure intrusion detection systems are configured to generate alerts for similar scanning patterns. Continuous monitoring of abuse report feeds can help identify emerging threats from this and related infrastructure.
