Critical Threat
IP 87.121.84.24 is a critical-risk address with a 10/10 threat level and 746 abuse reports tied to persistent hacking activity routed through a US-based virtual private server infrastructure operated by Vpsvault.host Ltd.
The IP has been flagged by automated honeypot sensors since August 2025, with the most recent reports logged in March 2026, indicating an active observation window spanning approximately seven months. All 20 of the most recent reports categorise the activity as general hacking, encompassing intrusion attempts and exploitation of vulnerabilities across exposed services. The address is associated with AS215925, a network operated by Vpsvault.host Ltd, a VPS hosting provider. Despite the substantial 746 total reports, the activity frequency score of 0/10 suggests the threat is historical rather than current, though the sustained report volume demonstrates persistent probing behaviour during the observed period.
Hacking activity as recorded by honeypot sensors typically encompasses a broad spectrum of intrusion techniques including brute-force authentication attempts, vulnerability scanning, and exploitation of unpatched services. The confidence score of 66% indicates moderate certainty that the activity observed is genuinely attributable to this IP address, though some reports may involve spoofed source addresses or relay traffic. The dominance of hacking-category reports across recent submissions signals that automated attack tools are actively targeting services exposed to this address, with the intent of gaining unauthorised access or compromising systems.
Site operators should implement automated blocking tools such as fail2ban to ban IPs after repeated failed authentication attempts, enforce strong password policies and multi-factor authentication on all accessible services, maintain regular patching cycles for exposed software to eliminate known vulnerabilities, and configure network-level rate limiting on commonly targeted ports to reduce the effectiveness of scanning and brute-force campaigns.
