SSHamble v0.0.3 is live with support for compromised host key detection through a data integration with Hanno Böck's lovely @badkeys project:

https://github.com/runZeroInc/sshamble

$ go install github.com/runZeroInc/sshamble@latest

$ sshamble badkeys-update

$ sshamble scan --checks=badkeys-blocklist 192.168.0.0/24

[*] 192.168.0.9:22 badkeys-blocklist found compromised hostkey: https://github.com/SecurityFail/kompromat/blob/master/src/firmware/rapid7-ssh-badkeys/host/Trendnet_tew816drm_rsa.key
