Maximum Danger
IP 103.162.15.126 is a critical-risk address originating from Vietnam that has been associated with high-volume SSH brute-force intrusion attempts, accumulating 13,612 abuse reports across automated honeypot sensors within a concentrated two-month window between October and November 2025.
The IP operates within AS135951, managed by Webico Company Limited, and ranks at the maximum threat level of 10/10 according to available telemetry, though the 59% confidence score indicates some uncertainty in attribution. The volume of reports is exceptionally high, with 20 separate honeypot sensors detecting the malicious activity. While recent first and last reported dates span only October and November 2025, the sheer number of detections demonstrates sustained, automated scanning behavior rather than isolated probes. The dominant threat signatures match SSH brute-force patterns alongside general hacking reconnaissance, suggesting the address participates in credential-stuffing campaigns targeting exposed SSH services.
SSH brute-force attacks represent one of the most prevalent pathways for unauthorized server access, with automated tools systematically attempting credential combinations against publicly accessible daemons. A successful compromise grants attackers persistent access to the target infrastructure, enabling data exfiltration, cryptocurrency mining, lateral movement within networks, or incorporation into botnets. The scale of activity attributed to IP 103.162.15.126 indicates systematic, coordinated scanning consistent with opportunistic attacks targeting internet-exposed services at volume rather than precision-focused intrusion attempts.
Operators should implement immediate blocking of this address at the network perimeter, deploy rate-limiting on SSH authentication endpoints, and enforce key-based authentication to eliminate password-based login vectors. Configuring fail2ban or equivalent intrusion prevention tools provides automated response capabilities, while disabling root SSH access and changing default ports reduces exposure. Continuous monitoring of authentication logs for patterns associated with this source address is strongly advised.
