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.
Suricata IDS Alert
Suricata intrusion detection flagged this IP for malicious network behaviour — including port scanning, exploit attempts, botnet activity, or known attack signatures. The specific signature is shown in the report list below.
