Attack Analysis
SSH: Login Attempt — Non-Existent User
This IP attempted to authenticate via SSH using a username that does not exist on the system. This is characteristic of automated credential-stuffing attacks cycling through common username wordlists (admin, root, ubuntu, pi, etc.).
SSH: Invalid User Flood
This IP attempted SSH logins using 5 or more invalid usernames within 2 minutes — a credential-stuffing attack cycling through common account names (admin, root, ubuntu, deploy, pi). This indicates an automated tool probing for default or common accounts.
