Critical Alert
IP 61.7.241.149 is a critical-risk address operating from Thailand's Communication Authority of Thailand (CAT) network that has generated 712 total abuse reports, primarily linked to SSH brute-force attacks targeting exposed servers worldwide. The IP carries a maximum threat level of 10/10, reflecting automated honeypot detections that confirm sustained malicious activity during September 2025. Despite a 60% confidence score, the sheer volume of reports from 20 distinct honeypot sensors validates that this address is actively engaged in credential-guessing campaigns against SSH services. The dual threat classification of Hacking and SSH activity indicates the actor is running automated intrusion tooling designed to systematically probe authentication mechanisms on a global scale.
The evidence base for this briefing derives entirely from community-sourced abuse reports and automated honeypot detections logged during September 2025. The AS9931 network operator, The Communication Authority of Thailand, routes this address within Thai infrastructure, yet the detection footprint spans multiple sensor networks. The 712 total reports break down across 16 general hacking categorizations and 4 SSH-specific incidents, with honeypot event logs specifically documenting brute-force attempt patterns. Activity frequency registers as minimal in recent intervals, but the historical report volume demonstrates persistent engagement over the reported month rather than isolated probing.
SSH brute-force attacks represent one of the most prevalent initial-access vectors in internet-facing server compromise. Threat actors deploy automated tools that cycle through username/password combinations against open SSH ports, exploiting weak or default credentials to gain shell access. Once inside, attackers typically install persistent backdoors, cryptocurrency miners or pivot to lateral movement within compromised environments. The volume of reports against IP 61.7.241.149 indicates the address is likely part of a botnet or proxy infrastructure cycling through target networks, making any exposed SSH service a potential entry point if hardening measures are not in place.
Site operators should treat IP 61.7.241.149 as a blocking candidate at the network perimeter or firewall level given its confirmed malicious history. Deploy key-based authentication exclusively for SSH access, disable root login and change the default port to reduce automated targeting. Implementing fail2ban or equivalent rate-limiting tooling will detect and auto-block repeated authentication failures originating from this address. Regular monitoring of authentication logs for entries from this IP range, combined with patch management for SSH daemons, will further reduce exposure to the intrusion techniques this actor employs.
