Notable Threat
IP 81.29.142.6 is a high-risk address linked to 448 abuse reports and a threat level of 8/10, indicating sustained malicious activity originating from this Russian network operator. The dominant threat category is general hacking activity, accounting for the majority of recent reports, with additional exploitation indicators, email spam attempts, and web application probing detected over the February–May 2026 reporting window.
Automated honeypot sensors across 20 detection points logged the bulk of these reports, establishing a 93% confidence score in the malicious classification. The IP traces to AS210259, operated by LLC Applied Computational Technologies in Russia, with activity first reported in February 2026 and continued engagement through May 2026. The moderate activity frequency rating of 4/10 suggests persistent rather than burst-based behaviour, consistent with automated scanning or sustained intrusion campaigns targeting exposed services. Intrusion-detection signatures flagged application-layer anomalies, while additional reports documented SMTP abuse, web application reconnaissance, and malware or exploit-related connections.
Hacking activity detected from this address encompasses multiple intrusion vectors, including vulnerability exploitation, unauthorized access attempts, and probing of web-facing applications. The combination of application-layer alerts, SMTP spam indicators, and exploitation signatures suggests an attack platform capable of conducting credential-guessing, service enumeration, and potential secondary-stage payloads. An exposed service targeted by this IP faces risk of unauthorized access, data exfiltration, or further compromise if exploitation succeeds.
Site operators should consider implementing proactive blocking or rate-limiting for this address range at the network perimeter. Deploying stronger authentication mechanisms such as key-based authentication, multi-factor authentication, and account lockout policies reduces the effectiveness of credential-guessing attempts. Regularly reviewing intrusion-detection logs helps identify and block scanning patterns associated with this source. Operators may also wish to notify the hosting provider or network operator regarding the abuse patterns, as the address may represent a compromised host being weaponized without the owner's knowledge. Tools such as fail2ban or similar dynamic firewall rules can further mitigate repeated connection attempts from sources like 81.29.142.6.
