Attack Analysis

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.
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: SSH Port Scan
Suricata detected automated SSH port scanning from this IP. SSH scanners map targets before launching credential brute-force attacks. This is the reconnaissance phase of a larger attack campaign.
IDS: Threat Intel — CINS Active Threat
This IP appears in the CINS (Collective Intelligence Network Security) Active Threat Intelligence feed — a real-time blocklist of IPs with poor reputation scores derived from observed malicious activity. CINS-listed IPs are actively engaged in attacks at the time of detection.
