Severe Risk
IP 5.182.83.231 is a maximum-threat-level address that has accumulated 318 abuse reports across 20 automated honeypot sensors over approximately seven months of activity, with its dominant behaviour pattern centred on persistent SSH brute-force intrusion attempts originating from Spanish telecommunications infrastructure.
The IP, registered to Avatel Telecom, SA (ASN AS200845) in Spain, carries a threat level of 10 out of 10 with an 84% confidence score indicating highly reliable detection data. Since first reported in October 2025 and remaining active through May 2026, this address has generated consistent alarm with an activity frequency rated at 6 out of 10. Of the 318 total reports, SSH-related activity dominates with 18 distinct categorised incidents, complemented by 7 reports of general hacking intrusion activity and 2 reports flagging the IP as an exploited host itself. The attack-pattern logs document multiple fail2ban triggers recording 25, 34 and 29 violations respectively, alongside Suricata alerts noting active SSH sessions on expected ports and ongoing brute-force credential-guessing campaigns.
SSH brute-force attacks represent one of the most prevalent and effective initial-access techniques employed by threat actors to compromise servers exposed to the internet. By systematically cycling through common username and password combinations, attackers attempt to authenticate to the target service until valid credentials are discovered. The real-world risk extends beyond mere unauthorised access to potential data exfiltration, lateral movement within networks, deployment of secondary payloads such as cryptocurrency miners or ransomware, and complete host takeover. When an IP is additionally flagged as an exploited host, it suggests the address itself may be a compromised system being weaponised by attackers, meaning its owner may be an unwitting participant in further attacks against other targets.
Site operators with publicly accessible SSH services should immediately block IP 5.182.83.231 at the network perimeter or firewall level to eliminate the threat vector entirely. Implementing key-based authentication exclusively, disabling password-based SSH login, and changing the default SSH port from 22 to a non-standard port substantially raises the barrier against automated attacks. Deploying tools such as fail2ban to dynamically ban IPs after repeated authentication failures provides an additional automated defence layer. Continuous monitoring of authentication logs and implementing intrusion detection rules that flag unusual SSH session behaviour remain essential for early identification of any successful compromise attempts.
