Critical Threat
IP 27.79.41.119 is a high-risk address linked to SSH brute-force attacks and general intrusion activity, originating from Vietnam under Viettel Group's network (AS7552), with a maximum threat classification of 10/10 and 953 cumulative abuse reports submitted by automated honeypot sensors.
The IP was first and most recently reported in December 2025, with recent submissions indicating 14 hacking-category incidents and 6 specifically categorized as SSH attacks detected across 20 distinct automated honeypot sensors. Despite the substantial historical report volume, the activity frequency metric registers at 0/10, suggesting the address may currently be dormant or operating intermittently rather than sustaining continuous aggressive behavior. The 60% confidence score reflects the certainty that this IP is actively involved in hostile scanning, though the totality of its campaign scope carries some uncertainty.
SSH brute-force attacks represent one of the most persistent threat vectors facing publicly accessible servers, whereby automated tools cycle through common username-password combinations to gain unauthorized shell access. A successful intrusion can grant attackers root-level control, enabling data exfiltration, cryptocurrency mining deployment, lateral movement across internal networks, or incorporation into botnets. The general hacking activity associated with this IP suggests additional exploitation attempts beyond credential guessing, potentially including vulnerability scanning or probing for misconfigured services.
Site operators exposing SSH services to the internet should enforce key-based authentication exclusively, disable root login, and consider relocating SSH to a non-standard port to reduce exposure. Implementing automated blocking tools such as fail2ban or comparable intrusion-prevention systems will detect and quarantine repeated authentication failures originating from this address. Continuous monitoring of abuse reports and maintaining current patch cycles for any exposed services further mitigates the risk posed by credential-guessing campaigns emanating from this Vietnamese infrastructure.
