Botnet InfrastructureChinaNet (AS4134, China Telecom)
ChinaNet (AS4134) is one of the highest-volume attack-originating ASNs globally, consistently ranking in SANS/DShield top-10 attacker lists. Activity ranges from compromised consumer endpoints to dedicated scan infrastructure. SSH brute-force from this network targets common username dictionaries at scale — automated, persistent credential-harvesting botnet behavior.
Attack Analysis
Port 22 Honeypot Probe
This IP connected to a fake SSH honeypot — a port 22 listener that is not a real SSH server. This is an automated scanner fingerprinting targets before launching a brute-force campaign. Legitimate systems never probe port 22 without a specific reason; this activity is virtually 100% malicious.
IDS: Database Port Scan
Suricata detected this IP scanning database ports (MySQL, PostgreSQL, Redis, MongoDB). This is reconnaissance to find exposed database services for direct exploitation or credential brute-force. Database ports should never be reachable from the internet.
