Attack Analysis
Slow SSH Preauth Scan
This IP repeatedly connected to SSH, collected the server banner and host key, then disconnected before authenticating — multiple times over 30 minutes. This slow scan pattern maps SSH versions and keys while staying below rate-limit thresholds. It is used exclusively by botnet scanners preparing for brute-force attacks.
