SSH: Invalid Header
This protocol anomaly is an invalid SSH header. SSH headers always start with "SSH." This could indicate someone trying to tunnel through the SSH port.
Extended Description
If an SSH message does not start with the string "SSH", this could indicate an SSH configuration or implementation error. It also could indicate that an attempt to transfer tunneling traffic over an SSH port, or an attack against an SSH server or client is underway.
