check-host.net

check-host.net – our primary information source. We use it to find out where the target is located and how its defense mechanisms work.

FOFA example

ping.pe

ping.pe – a more advanced alternative to Check-Host. We use its MTR (multi-trace route) tool for advanced L4 testing. Sometimes the routers providing internet access to the target are more vulnerable than the target itself.
