Goal

Detect the SSH interesting hostname login notice.

Strategy

This rule monitors Zeek logs for the notice SSH::Interesting_Hostname_Login. The notice is generated if a login originates or responds with a host with a reverse hostname that looks suspicious.

Triage and response

Identify the owners of the host that has been accessed.
Work with the team to understand if this authentication was expected/legitimate.
1. If it is determined that the activity is malicious:
- Block the IP address, if it aligns with organization incident response processes.
- Begin your organization’s incident response process and investigate.
