Notable Threat
IP 199.45.154.156 is a high-risk address originating from the United States that has accumulated 304 total reports across automated honeypot sensors since October 2025, with a current threat level of 8/10 indicating significant malicious activity. The dominant threat category is general hacking activity, accounting for the majority of recent reports, supplemented by smaller volumes of exploited-host and IoT-targeted incidents. With a confidence score of 71%, there is reasonable certainty that this IP poses a genuine threat rather than a false positive.
The IP is registered to network operator CENSYS-ARIN-03 within ASN AS398722 and has been tracked for approximately seven months, with the most recent activity occurring in May 2026. Detection sources exclusively comprise 20 automated honeypot sensors, which flagged repeated attack patterns consistent with connection attempts, IoT and industrial control system targeting, and broader malware or exploit activity. The activity frequency rating of 3/10 suggests persistent but not excessively high-volume behavior, likely representing targeted probing rather than bulk scanning. The combination of 304 total reports against this modest activity rate indicates a sustained, methodical threat presence rather than opportunistic noise.
The primary hacking activity associated with this IP aligns with general intrusion attempts, vulnerability exploitation, and unauthorized access attempts against exposed services. The presence of IoT-targeted reports suggests this address may be conducting reconnaissance or exploitation against poorly secured connected devices, industrial systems, or smart infrastructure. The exploited-host reports indicate that either this IP itself is operating from a compromised system or it is targeting compromised infrastructure, raising questions about its operational autonomy. Together, these patterns suggest an actor engaged in persistent probing of internet-facing systems with particular interest in IoT and ICS environments, potentially deploying malware or exploiting known vulnerabilities to establish footholds.
Site operators should block IP 199.45.154.156 at the firewall or network edge to prevent direct connection attempts. Implementing fail2ban or similar intrusion-prevention tools can automatically detect and respond to the observed attack patterns. Exposed services should be audited for vulnerabilities, especially those affecting IoT and industrial control systems, and unneeded services should be disabled to reduce attack surface. Continuous monitoring with updated threat-intelligence feeds will help maintain protection as this IP's activity evolves.
